Live Q&A on COVID-19 and Omicron sub-variant BA.2 with Dr Maria Van Kerkhove and Dr Abdi Mahamud – 8 February 2022
00:00:53
AK Hello,
good afternoon, good evening and good morning to everyone joining today’s Live
Q&A or #AskWHO about COVID-19. We will answer your questions about the
current situation and, in particular, about Omicron and what we know about its
sub-lineage, BA.2. It has been there out of high interest.
My name is Aleksandra Kuzmanovic and I’m very
pleased to be joined by Dr Maria Van Kerkhove, as usual, but we also have a new
guest for the first time. He’s not a new colleague but is new in this
conversation. Dr Abdi Mahamud, who is our Incident Manager. Good afternoon, Abdi.
AM Good
afternoon, Aleks.
00:01:34
AK Thank
you for your time to be with us today and maybe you can tell us a bit about
your work and when we say Incident Manager, what does that mean in WHO? What is
your job, exactly?
AM That’s
a tall order. Thanks, Aleksandra, for having me and Maria, for doing this for
almost a third year into this and for your facilitating. In terms of when we
have an event in WHO, we have what we call the Incident Management System,
where we bring all the expertise across the house and we create different
pillars, from the epidemiology, to the technical network that Maria is leading,
in infection prevention, clinical management, to operations, logistics and
supply, all aspects are blocked together, under the Incident Management
Support. So, we have ten pillars plus one pillar, which is the research that
oversees.
So, as the Incident Manager, I’m kind of making
sure that everyone is coordinated, both the technical and overall management
and operational aspects. We have the same at a regional level and then also at
a country level, bringing all the expertise across within WHO.
00:02:41
AK Thank
you so much, Abdi. We are really pleased to have you here and I’m sure our
viewers are happy to meet you as well if they haven’t seen you in other
channels before. As usual, I would invite you to send us your questions using
the hashtag, #AskWHO, if you’re watching us on Twitter. If you’re watching us
on other platforms, please leave your questions in the comments section and I
will pass them to Maria and Abdi.
Before we start receiving some questions, maybe
Abdi you can take this question. We normally start with the epidemiological
update. Normally, Maria does it but as we have an Incident Manager, who
oversees all the operations, so maybe you can do it today. What’s the current
situation with cases, with mortality rates, and where are the hotspots at the
moment?
AM Thanks,
Aleks. Just to start, I hope one day we will see when epidemiology becomes
boring again, so that we more life saved. In terms of where we are right now,
in the last one week we have over 19 million cases reported and because of the
change in tests different countries have adopted it’s very hard to make minutes
of where those cases are. What is more important is the number of deaths
reported last week, 68,000, and that has increased by 7%.
So, while we are paying close attention to the
trend, I think what will be more important moving forward will be the number of
hospitalisations in cases because this is becoming more difficult and
challenging. In terms of if you’re dividing by the WHO regions, the main cases
we are seeing now of the deaths are in the US and I will spend some time there.
00:04:26
Within the US, where we see trends going down in
most of the places, other parts of America, particularly Southern America, have
seen an increase, so there is variation. In terms of when you move to Africa
region, where Omicron has started, it is going down.
Europe, the western side, the wave is going down
but it is picking up in the eastern side of Europe and is really affecting
places with low vaccination and a weak health system. So, Eastern Europe and
Central Asia will be something.
Then, coming down through the East Mediterranean
region, we see a big uptick in Gulf countries, countries that already had a
vaccination but also countries like Afghanistan and Somalia with very low
vaccine
Moving on to the Southeast region, SEARO, India and Thailand. We have seen the
southern part but it is now slowly shifting to East Asia, Thailand. So, we’re
seeing a mixed picture and WPR countries who have just celebrated the Lunar New
Year, are seeing an uptick of cases.
South Korea and all these have successfully managed
now. In comparison, when you’re reporting one million cases in other parts of
the world, even 10,000 cases is a big number for them.
00:05:44
So, it’s a mixed number. Countries see an
increasing trend, others steady, and others down, but unfortunately in the
third year of this we’re having more deaths reported. DG has touched on Omicron
since it was discovered, how many declared. Now, just look at the numbers,
thanks to the EPI team, 130 million cases since Omicron was declared as a VOC
and 500,000 deaths.
In the age of effective vaccine, half a million
people dying is really something. I think if there is a word beyond tragic,
it’s sad, and unfortunately out of that 500,000, 100,000 are in the US reported
since Omicron. So, while everyone was saying Omicron is milder, I think we
missed the point that half a million people have died since this was detected.
The US in the last 24 hours, I was just looking
at the number, 3,400 and someone smarter than me made a comparison, saying that
the Boeing 737 Max, two of them crashed in 2018-19, 346 people died. So, if you
take the number of just the last 24 hours in the US, that’s 18 Boeing 737s
crashing every day, so it’s beyond tragic that occurs in a country that has
free vaccine.
So, we really need to vaccine people who have
not been vaccinated and reach the 1.1 billion people in Africa but also the
millions of people in the US who are still resisting vaccination. Thank you. It
took me long but I just wanted to put it in a context.
AK Thank
you so much, Abdi. This was great. We haven’t done this session in a couple of
weeks, so we really needed a more detail update. Maria, looking into this
epidemiological situation and tragic situation, basically, where we lost half a
million people since Omicron emerged and became a Variant of Concern.
00:07:48
So, at which stage of this pandemic are we? We
have safe and effective vaccines that prevent severe disease and deaths, and we
have other tools, and now we are seeing an increase in the number of deaths.
So, where are we going and what is your advice on what we need to do urgently?
MK Well,
I think as Abdi has pointed out, it’s a very dynamic situation globally and the
sheer number of cases are astounding with Omicron. The way that Omicron has
replaced Delta around the world so quickly, the sharp peaks that we’ve seen, we
literally have had to redraw the scale of the epidemic curve that we have been
using and it makes the previous peaks look almost flat.
We know that those are underestimates of the
true number of cases and one of the things that’s important to point out is
where we are in this. We’re still in the middle of this pandemic. We’re getting
closer to the end. I hope we’re getting closer to the end of it every single day
but it’s up to us on how quickly we get there.
Many countries have not passed their peak of
Omicron yet, so while some countries are seeing a decline in cases in Omicron,
others have not yet reached that peak, so we will still continue to see a large
number of cases.
00:09:00
The more concerning thing for me, and as Abdi
has pointed out, is the number of deaths that are increasing for the fifth week
in a row, half a million people that we know about have died. The number of
people who have probably died from COVID is much higher than that because we
don’t have adequate reporting systems around the world.
But, of the last five weeks, we’ve seen an
increase in deaths and the fact that we are seeing an increase in deaths when
we have safe and effective vaccines, when more than ten billion doses of
vaccines have been administered to date, when we have diagnostics that work,
when we can get patients into the clinical care pathway and save people’s
lives, this is beyond tragic.
There’s a lot of emotions that I think all of us
have on this but it’s about what we do with those emotions and how we actually
turn that into action because we can save lives now. So, where we are in this
pandemic, the virus is circulating at a very intense level.
We have the Omicron variant, which is the fifth Variant
of Concern that WHO has classified as a Variant of Concern at the global level
but you have to remember that this virus still continues to evolve. There are
four sub-lineages of Omicron that we’re tracking. Let me say that again. There
are four sub-lineages of Omicron that we are tracking. We have the BA.1, the
BA.1.1, the BA.2, the BA.3. This is all Omicron, and it is all the Omicron Variant
of Concern but we are watching this virus evolve in real time.
00:10:33
So, with good sequencing and good detection
capacities around the world, we’re tracking what are the proportion of these
sub-variants that are circulating. Now, we already know that Omicron has a
growth advantage. It is more transmissible compared to other Variants of Concern.
It also has properties of immune escape.
But, we know some of the sub-lineages, BA.2, has
a growth advantage even over BA.1, which means that as this virus continues to
circulate, we will now see an increase in BA.2 with this increased growth
advantage over BA.1. So, for the person out there, everybody that’s out there that’s
watching this, what is important for you to know is that this virus continues
to be dangerous. This virus transmits very efficiently between people but
there’s a lot that you can do.
At a global level and as an organisation, what
we’re doing is working with governments, we’re working with our partners to do
two major things. One is to increase vaccination coverage among those who are
most at risk in all counties, not just some countries, and making sure we reach
that 70% target by June 2022.
But, we’re also trying to do everything that we
can to support the reduction in transmission. We will not be able to prevent
all transmissions. That’s not the goal. To prevent all infection and all
transmission, that’s not attainable at this point but we need to drive
transmission down because if we don’t, we will not only see more cases, more
hospitalisations, more deaths, we will see more people suffering from
post-COVID condition, long COVID, and we will see more opportunities for
variants to emerge.
00:12:07
So, it’s a very dangerous situation that we’re
in, three years in. I know everybody that’s watching doesn’t want to hear about
this anymore and wants this to be over. We do too. We would give nothing for this
pandemic to be over and for us to be able to move on and to get back to our
normal lives, but we’re still very much in this and we still need people to be
careful.
So, where you live, still take measures to
reduce your risk and your exposure to the virus. Wear a mask. Physical
distance. Wear a well-fitting mask, please, over your nose and mouth. Wearing a
mask under your chin, off of your ear is useless. Wear a well-fitting mask, the
best mask you can get a hold of, over your nose and mouth with clean hands.
Physical distance. Improving ventilation. Avoiding crowds for now.
We will not be in this situation forever. That’s
my last point. We will not be in this situation forever and the pandemic will
end but how quickly we get there is really up to us.
AK Thank
you so much, Maria. We have received a lot of questions on this BA.2
sub-lineage but I’m also seeing some comments that our sound is okay but not
perfect for everyone. So, please give us a minute or maybe even less. We will
go on slide and our AV team behind the scenes is going to fix the sound and you
can hear us even better. So, stay with us, please.
00:14:07
Thank you so much for staying with us. Chris, Mark
and Jill, behind the scenes, have fixed the problem and I really hope you hear
us even better now. Maria, a lot of questions on BA.2. How serious the variant
is? What are the symptoms? And, also, as Abdi explained and yourself, that we
have a significant increase in deaths, are these deaths linked to this
sub-lineage?
MK This
sub-lineage of BA.2 is Omicron. What we are able to do with good sequencing is
to determine which sub-lineage is circulating. We’re really in a good position
to track this virus globally. We’re working with partners around the world to
increase testing, increase surveillance, increase sequencing. That needs to
continue to improve because we need better geographic sequencing around the
world. So, I thank all of our partners who are working so hard on this to
improve sequencing capacities around the world.
BA.2 is Omicron, so it’s a Variant of Concern.
It’s already classified as a Variant of Concern. Our understanding of Omicron,
as a whole, and we have researchers around the world that are doing different
types of testing, different types of studies, different types of experimental
study on BA.1 compared to BA.2, but for the general public out there what is
important is to talk about Omicron as a whole.
Our understanding of Omicron is that people who
are infected with Omicron can have a range of symptoms. They can have no
symptoms at all and be completely asymptomatic or they can develop severe
disease and people are also dying from Omicron. On average, we know that there
is lesser risk of needing hospitalisation if you are infected with Omicron
compared to Delta, but that does not mean that it is a mild disease.
00:15:56
There’s a lot of narrative that’s out there that
suggests that Omicron is a mild disease. That is not true. It can be mild for
some individuals, as can the other variants, but we need to make sure that
people protect themselves about getting infected because everybody is at risk
of developing severe disease.
With Omicron, we know people with underlying
conditions are at an increased risk of severe disease, people of older age.
Risk of severe disease increases with age and risk of severe disease increases
if you’re not vaccinated. One of the most important things people can do to
keep themselves safe is to get vaccinated.
The vaccines are designed to prevent severe
disease and death and they are incredibly effective, even against Omicron. We
are seeing a slight reduction in efficacy but they still protect people from
developing severe disease and dying and that’s important. So, when it is your turn,
please get vaccinated. This is one of most important things that can do and
this is why WHO and partners are working so hard to make sure that there is
access to vaccines for people around the world, not just in some countries.
But, in terms of what we understand of BA.2
compared to BA.1, BA.2 is more transmissible than BA.1, so we expect to see
BA.2 increasing in detection around the world. There isn’t any indication to
suggest that there’s a difference in severity of BA.2 compared to BA.1 but it’s
still very early days.
00:17:24
The studies are really just underway and, again,
we’re working with so many people around the world and learning this
information in real time. So, for the person out there watching this, please do
what you can to get vaccinated when it is your turn, receive your full course
and also take measures to reduce your exposure where and when you can.
AK Thank
you so much, Maria. Abdi, maybe I can pass this question to you, coming from
Veronica Douglas, watching us on Facebook. Can someone be infected with more
than one variant of COVID-19 at the same time?
AM Thanks,
Veronica. That’s an excellent question and maybe a billion dollar question that
we are all trying to answer, but we go back to what we have learnt so far
dealing with the other variants, we have the way of protecting ourself and that
is the vaccine and getting vaccinated.
With other coronavirus and another variants,
unfortunately it wins or escapes with time. So, the body, when you get an infection,
you have an immediate defence that’s call natural innate immunity and then you
develop what we call the B cells and the T cells. The B cells produce
immunoglobulins. You maintain those immunoglobulins for a certain time and then
they go down after three to six months.
This is just an average and the travel, the
flows of the average. So, please take what’s true for the average may not be
true for that individual, Veronica. So, mostly between six to 12 months there’s
available data. When those immunity go down and you will get exposed, and
that’s why we’ve been saying continue protecting because your immunoglobulins
have gone down, your first line of defence have done down, you can get
reinfected.
00:19:11
But, when you’re reinfected, because you already
knew the virus or the variant, your body will kick in your second layer, your
memory B cells, your T cells and you will not get severe disease. While you may
get infection, a mild infection, these vaccines will protect you from getting
hospitalised and from getting to an ICU and, sadly, to death.
Right now, the main question from everyone, if I
got BA.1, can I get BA.2? We don’t know. We haven’t had time and, for WHO, we
use 90 days between the two infections. So, we’re still just starting the
period. So, if the question is related to if you got Omicron BA.1, can you get
BA.2? We don’t know yet.
But, the two cousins, that’s what I wanted to
say, Omicron BA.1, BA.2, these are all cousins. They share a common ancestor
some time back. Hopefully, the body, and that’s hope, it’s not a strategy, but
what we have learnt in all this Delta, Omicron, that the vaccine will protect
you from getting hospitalised and from death.
MK Can
I add something to that because I think this is important, what Abdi was
describing. When we look at reinfection, we look at this 90-day period and
there’s not really enough time. Since Omicron was first reported at the end of
November, we’re still in the early days of Omicron, even though we’ve seen this
huge spike.
00:20:31
One of the thing we’re tracking on the epidemic
curves and, of course, this is based on surveillance, we’re looking at how the
curves go up and how the curves go down. One of the things we have our eye out
on is on the decline. Countries are in very, very different situations based on
how they’ve handled this virus since the beginning and the population level
immunity, their capacity to respond, the tools that they have.
So, the decline in the latest peak will be
different, based on different countries. Some countries saw a very sharp
increase and a very sharp decrease. Now, that we see BA.2 increasing in
prevalence in terms of how much is circulating, we have to see what that
decline looks like.
If the epidemic curves go down sharply, if they
continue to go down in the trends that they’re going down, then we won’t see
this signal of reinfection, given that we don’t have the 90 days to be able to
detect with sequencing.
So, what we’re looking for is the decline
starting to slow? Is it a sharp decline or is it more of slow decline? And
that’s based on a number of different factors. As Mike always says, coming down
the mountain is quite bumpy and it takes a long time to get down.
You’ve actually heard us say that over several
peaks ago but with BA.2, we’re trying to keep an eye out very closely to detect
any signals that we may start to see an increase again. We don’t see that yet. So,
that answer, as Abdi said, we don’t know yet and I think it’s really important
for us, as we speak, we speak telling you what we know, telling what we don’t
know and telling you what we’re doing to find out.
00:22:09
I have been a little bit concerned. If I could
just take a moment to say, I’ve been a little bit concerned about some of the
public comments that we are seeing out there with people speaking with such
certainty. There’s still a huge amount of uncertainty.
We know a lot about this virus but we don’t know
everything and, quite frankly, the variants are the wildcard. We are tracking
this virus in real time as it mutates, as it changes and we have an excellent
group of people around the world who are working with us to do that, but this
virus has a lot of room to move.
Omicron is the latest Variant of Concern. It
will not be the last Variant of Concern that WHO will speak about. The next one
that will come, hopefully it will take some time to get there but with the
level of intensity of spread, the possibility that we will have other variants
is really high. So, we need to ensure that we, again, not only increase
vaccination coverage but we also take measure to reduce the spread.
AK Thanks
so much to both of you. You also answered Dianne Tenney-Adams’ question about
reinfection between Omicron and BA.2, so we got two questions answered at the
same time.
Some people are asking about if we know the
scale of infections in people who had three doses and those countries that have
introduced, heavily, booster doses. Do we see any different epidemiological
trends in those countries?
00:23:36
MK Maybe,
I could start. We do see a very significant difference in individuals who are
vaccinated with one dose, two doses and some people have had three doses as the
primary course of their series, a significant reduction in hospitalisations and
deaths. This is from Omicron, from other Variants of Concern, and I think
that’s one of the biggest factors that is really, really critical that people
hear out there.
When it is your turn get vaccinated and fight,
as much as you can, for vaccine equity around the world for others so that they
receive their first and second doses. There are some differences in terms of
the vaccines that are out there. There are several WHO Emergency Use Listing
that we have approved and there are more that are being evaluated but whatever
vaccine, if you are offered, please get vaccinated when it is your turn.
If you’re offered a booster, you’ve also heard
us say take that booster but, again, fight for what you can to ensure that
vaccines are reaching people around the world. We evaluate vaccine
effectiveness several different ways and we are working with several different
groups, our technical advisory groups who are assessing this information in
real time with the manufacturers, as data comes out from the manufacturers, as well,
and we try to summarise this each week on our website.
00:25:05
We have these very detailed tables that go out
and actually describe each study and say this is the study that was done, this
is how many people that were followed, this is what they were measuring and
this what we see in terms of efficacy.
But, bottom line, people who have been
vaccinated are significantly less likely. I don’t know the actual numbers, 20
to 97 times more likely not to need hospitalisation or die if they’re
vaccinated compared to those who don’t. So, there’s a real importance that we
still make sure that everybody receives their vaccines.
AK Thank
you so much, Maria. Abdi, please go ahead. Sorry.
AM I
just want to add on that because sometimes we mix between the individual
protection and the population protection. If you look at the individual level,
your saving account needs to go up and that’s by protection. How do you invest
in that? Getting the first dose, the second dose and some other people a third
dose.
Every time the body sees these foreign bodies,
it says this is serious, let me think on it. It puts an investment to produce
antibodies but after time it says I have thousands of other diseases that I
need to worry, it goes down. Then, you get again a second dose, it says, wow,
this is serious. Let me take it serious again. Then, when you expose it again
to the third time, it’s like, wow, this is dangerous because I need to invest
more, maintain a high level of quality antibodies, T cells, B cells because I’m
exposed to that. So, at an individual level we talk about that.
00:26:45
Then, at population level and that’s where a lot
of the discussion that is so hard to explain, talking about the epidemiology,
about the severity, it really depends how much population. So, sometimes
comparing one country to another country, it beats the whole purpose. When you
have a young population who had three waves that was not mitigated and high
level of a vaccination, like South Africa.
We’ve been saying South Africa may have a high
population level. Because of South Africa, someone else starts complaining.
Another country has an elderly population, not vaccinated well and they haven’t
been exposed to the natural illness. So, it’s a complex interplay of you’re
individual, the type of vaccine you get, the booster and the environment where
you live and other measures you do.
So, in short, it’s very hard to make a
comparison between one country to another because it’s very unique for that
country and for its population. But, at individual level, absolutely, as Maria said,
you need to get vaccinated. If you’re in a country that you are lucky unlike
the three billion of the world where you don’t have the luxury of getting even
the first dose, if you’re in those countries with the vaccine, please get as
per the recommended things to protect yourself.
00:28:06
MK It’s
not related to the actual question but it relates to something Abdi said here.
Countries are in very different situations in terms of what they are able to do
right now and they’re looking to each other to say should I follow this model?
Should I follow what the UK is doing, or the US is doing, or Denmark is doing,
or South Africa is doing?
What we are asking countries to do is to really
assess where they are. Where are they in this pandemic in terms of the amount
of infection that has circulated, population level immunity, vaccination
coverage and in particular vaccination coverage among those who are most at
risk, not just the proportion of the population but is it really the right section
of the population that is vulnerable and what is the plan?
What are their access to tools? What is the
relationship that they have with their people in terms of trust, in terms of
the society’s ability to follow and to be enabled to follow the recommendations
that are being outlined. There is no one solution fits all out of this pandemic
but we do know what works. We know the elements and the tools of what works.
The implementation is what will vary and I think
that’s what we’re trying to think through into this year. We’re not looking at
revamping the strategy for COVID-19. What we’re looking for is adjusting it and
how do we take into consideration what needs to be done, what can be done given
the massive economic livelihood toll and human toll that this pandemic and the
fact that everybody is ready to be done with it.
00:29:44
Unfortunately, this virus is not done with us,
so we have to really remain vigilant. That doesn’t mean lockdown, it doesn’t
mean shutting down societies. What it means is applying the tools that
countries have at their disposal to save people’s lives now.
At least 68,000 people died last week from
COVID-19 that we know about. They don’t have the opportunity to move on, nor do
the 5.7 million people who have died so far. Let’s turn the tide. Let’s change
the trajectory of this with the tools that we have.
Now, we may not be able to prevent all
infections but we can prevent people dying right now. So, this is what we are
asking. What the Director-General has been asking for is a recommitment to this
while we balance the response. Increase vaccination coverage, get people into
the clinical care pathway, protect our health workers, while at the same time
reducing the opportunity for this virus to thrive, not even to spread but to
thrive.
We are still allowing this virus to circulate,
in some situations, unchecked and that’s dangerous and we shouldn’t be doing
this three years into this pandemic. Now is not the time to raise the white
flag. Now, is the time to use these tools more effectively and for governments
to support people in being able to keep them and their loved ones safe.
AK Thanks,
so much Maria. We have a question from Sara Downs. Do we expect masks to still
work against this transmissible virus?
00:31:13
MK Short
answer, yes, we do, but masks need to be work properly. We have advised on the
use of masks, a three-layer mask with the right types of materials that has the
right filtration, the right breathability. Just a piece of fabric is one
barrier but if you have a three-layered piece of fabric, with the right
filtration, with the right breathability that is fit properly over your nose
and mouth, that offers more protection.
We know that respirators offer more protection,
which is why health workers are wear respirators when they’re caring for
suspected or confirmed cases of COVID-19, and they still do work against
Omicron.
Omicron is incredibly effective at transmitting
between people but these tools work. So, this is also why we are recommending
to continue to wear masks, particularly when you’re in close proximity with
other people but especially when you’re indoors, and even if you’re vaccinated
because vaccines are incredibly protective against preventing severe disease
and death but they don’t prevent all infection, so they don’t prevent all
transmission.
Even though they are effective at doing that,
they’re not 100% effective in that case. So, please continue to wear you mask
and make sure you have clean hands when you put it on and take it off.
AK Thank
you so much, Maria. Abdi, maybe this one you can take. Ella O’Neal Belch is
asking what are the best precautions to take if you can’t have a vaccination?
AM If
you can’t?
AK If
you can’t have a vaccine.
00:32:41
AM That’s
a tough one. I think there are multiple. In the first two years we didn’t have
vaccine and we were able to beat this virus, so the measures at the individual
level, at the community level, the family, there’s a lot of things that you can
do and the loved ones can do.
We have not a good proportion but a certain proportion
of the population that for the underlying reason, whether it is congenital, that
may not be able or allergic. So, what I would recommend first is discussion
with your physician because your local physician will really know your profile
and what kind of medication they can give.
The good news right now, we have good, good
medication that came down, from the monoclonal antibody, to the oral
antiviruses, a lot of things that we can offer you and the vaccine platform is
changing so much. Our advice is continue protecting yourself. As Maria says,
masks do work. Avoid those risky settings, we say crowded places, reducing that
risk and then discussing with your local clinician, out of the monoclonal
antibody, the new therapeutics, which one.
I think even among the severe immunocompromised patients
have been given vaccines, unless you are allergic to it. So, vaccine will be
the best shot for it but it’s a unique situation and I recommend to discuss
with your local physician about other measures. But, the preventive measures we
applied for 1.5 years before we had a widespread use of vaccine worked and
saved lives, so continue doing that.
00:34:24
AK Thank
you so much, Abdi. We have a next question from Ria Deshpande, asking, and
she’s not the only one actually, about the effect of Omicron on other body
organs and long COVID after Omicron, if you have any new findings from
research.
MK There’s
a lot of work underway of better understanding Omicron and the diseases that
are caused. We haven’t seen a change in disease profile in terms of the type of
science and symptoms and, as I said, on average the risk of hospitalisation is
less compared to Delta, but we still see the full spectrum of disease.
There are many clinical studies that are
underway and we encourage countries to continue to use the clinical platform
that we have established which collects standardised data, so that we can
actually look at this in a real robust way.
There’s a lot of questions that we receive every
day on long COVID, post-COVID condition. Again, Omicron has only really been
circulating for a short amount of time. It takes some time for people to be
infected, to go through the full disease and then what we’re looking at when we
look at post-COVID condition, that’s usually around 90 days after symptoms
resolve, where people are seeing a lot of longer-term effects.
00:35:41
There really isn’t any indication to suggest
that we would see a difference in the percentage of people that may suffer from
long COVID but we don’t have a full understanding of long COVID yet. There are
people that are around the world that are looking at how SARS-CoV-2, this
virus, and all of the different variants affect the body and the different
organs of the body.
We are learning that people who are suffering
from post-COVID condition, it affects all organs of the body, different organs
of the body, not all organs at the same time, and range in severity from people
not able to catch their breath, not able to exercise anymore.
We’ve seen some studies come out look at cardiac
effects a year out but this data is coming online and we need to make sure that
we have good cohorts of studies, these studies of individuals who are suffering
from post-COVID condition or may be suffering from post-COVID condition around
the world, not just in high-income countries but in countries all over, but we
don’t have a full picture of this yet.
I do think that people are starting to pay
attention more to post-COVID condition. This is something that we, as WHO, have
been working since the first six months of the pandemic and we’re very grateful
for the groups that reached out to us who said, look, we need people to
recognise that this is real.
We need good research on this. We need good
care, clinical care of dealing with the short-term and the long-term effects
and we need to make sure that there is good rehab. This is something WHO is
committed to with our Clinical Management Pillar under Dr Janet Diaz. We’ve had
a lot of seminars, we’ve had research studies established but it’s a work in
progress. We do not have the full picture of this yet.
00:37:23
This is another reason why we want people and
governments and everyone to focus on prevention of getting infected in the
first place because that is better in terms of any effect, short-term and
long-term, but we don’t have the full picture of this yet. We don’t know
everything yet on post-COVID condition.
AK Thank
you so much, Maria. Abdi, please.
AM I
just wanted to add that most of the time when people talk about COVID you think
is the upper respiratory disease. Unfortunately, COVID is a systemic disease
and that nuance a clinician can understand, someone checking. For the public,
it looks like because you just presented with sneezing or a cough, it affected there.
Unfortunately, it affects almost every part has been documented a complication.
Whether it is the virus, itself, or our immune system starts misfiring, we
really don’t know. There’s a lot of research going on.
The progression of those complications, Maria
just alluded to this excellent paper that was published in Nature. Literally,
it was affecting every part of the cardiovascular system one year down and
later. So, the risk and complication from COVID, when we see it is not as a
respiratory pathogen. Of course, that’s the way of entry, but it’s affecting
every part of your body because of the vessels. It can cause vasculitis. The
virus is so complicated, that’s why we say the only way you can do it is get
vaccinated and continue preventing it yourself, preventing it yourself with
those public health measures.
00:38:58
MK What
we have to look at is people who are infected and have COVID-19, people who are
suffering from longer-term affects that we are just learning about but those
long-term effects could be a few weeks, they could be a few months, they could
be a few years. We don’t know what that is yet.
So, as an organisation, as WHO, with governments
we need to plan for the longer-term. So, it’s not just now and, again, we’re
thinking into 2022 and how we end the emergency of this pandemic, but we have
to plan and we are planning for the longer-term and how we deal with the
effects of this.
And, we have to think not just COVID but mental
health effects and effects for people who have not received other vaccines for
vaccine-preventable diseases, people who didn’t get the care that they need for
cancer or for other treatments.
So, this is obviously quite a complex situation
that the world is in, that countries are in but this is all the more reason why
we need to end this emergency of COVID-19 and we have to end it as quickly as
possible. It’s in our hands and we need everyone out there.
Some people may think what can I do to help? You
can get vaccinated, if you have access to the vaccine. You can also take
measures to prevent you from getting infected because it’s not just even about
you and we want to protect you but we also want you to protect your family.
00:40:20
We also want you to alleviate pressure on the
health systems because if you get infected and you need clinical care, you take
up that bed, as you deserve to take up that bed, but you take that bed from
somebody else who may need it for another reason. It has a domino effect and
this is why it’s so critical that we really work to end this emergency this
year.
AK Thank
you both. Speaking of prevention and protection individuals but also protecting
populations and as Abdi explained that COVID is a systemic disease, way more
complex than we think as individuals. Last week we had some social media posts
published that Omicron is not a common cold, so our viewers are asking if it is
not a cold, why do we have countries saying that they are going to treat COVID
like a cold and from middle of February they are going to release all restrictions
including wearing masks?
MK This
is a complicated question. I think it was the Wordle.
AK Yes.
MK I
am probably the only person on the planet that doesn’t know what that is. I
apologise to my family. They keep sending me things but SARS-CoV-2 is a coronavirus
and the common cold viruses are coronaviruses, so there are people that are out
there that think that this virus may become more like the common cold in years
from now. And, that may very well be true but we’re not in that situation yet.
00:41:50
SARS-CoV-2, Omicron, the latest Variant of Concern,
is not the common cold. It still causes severe disease in many individuals and
with the huge number of cases that we’ve seen, we still too large of a
proportion of people needing hospitalisation and dying from this. So, it is not
the common cold. I forgot the second part of your question.
AK We
are seeing some countries lift all restrictions.
MK I
think countries are taking decisions based on the situation that they’re in and
countries are in very different situations. They are looking at the population
level immunity that they have from infection and from vaccination. They’re
looking at the capacities that they have to respond, to detect, to impose
measures, to lift measures.
They are looking at that adjustment and they’re
looking at different ways in which they can apply tools. We are recommending
that countries be cautious and to continue to use measures. I am not meaning
lockdown, where you shut down society, where you lock people away, that is not
what we are talking about, but to use tools to continue to drive transmission
down.
Countries have to take those decisions. We issue
guidance but the policies that countries take are up to the countries themselves.
We are working with them to ensure that they protect their own people but,
again, COVID-19 is a global problem. It’s a pandemic and it needs a global
solution. So, what we look at is, on the whole, what tools need to be applied
and we’re working with countries how they best implement them.
00:43:25
But, we are asking countries to continue to be
cautious and individuals to continue to be cautious as we go forward. Again, it
will not be forever. You will not need to wear a mask forever. We will not need
to physically distance forever but, for now, it’s really important that we be careful.
AK Sorry,
Abdi.
AM Thanks.
I just want to add why some countries can take those measures. There’s a
competition between our immune system and the virus and unfortunately the
virus, the way it is mutating, they say RNA virus, it has a good RNA enzymes
that proofreads them.
Unfortunately, Omicron has shown that whatever
our wishful thinking, it is always, so humility is required when predicting the
future because nobody knows what is going to happen and the next variant is going
to happen.
Yes, we want to build our protection, build the
population immunity to a certain level that even the next variant will not land
and not cause damage. So, it’s the key unlock, as I just alluded earlier on.
The variant will come and unlock and get a
smarter key. You have to start and design the lock again and then lock. But, if
you put fire extinguishers, and that’s what a lot of the countries are doing.
They have built every floor of their houses in the community they have fire
extinguishers. Once the variant comes and it starts, they will be able to
switch.
00:44:48
But, unfortunately, it is a copycat because what
certain countries have done, you don’t have any fire extinguishers, you don’t
have a health system, you don’t have anything but because of the pressure you
are seeing you want to take that. So, what we are calling that, still at
individual level, a country can decide but at the end of the day it’s your
individual risk that is going to matter.
Population and policy, later they will be
balancing public health, socioeconomic, all that into consideration. So, you
continue at an individual level with your measures so that you protect your
loved ones, and getting the necessary vaccination because we really don’t know
what is going to happen. I wish we knew what variant is going to come but
Omicron showed us that nature will always beat us, so we just need to build
that defence.
AK Thank
you, Abdi. Maybe you can take this question from Arsela Kuriskova. How to treat
Omicron? Just stay at home and take paracetamol and wait if it gets worse or
better?
AM For
WHO we issued several guidance. We have our Clinical Management and we also
have Home Care but I would really encourage her to get contact with her,
because we have seen a lot of young people who are healthy quickly
deteriorating. So, being in touch with your healthcare provider. It can be
managed safely at home care level by a lot of things we have in our guidance
but the first thing is to be in touch with your healthcare provider and that’s who
will guide you when you need referral because the assumption because you are
young and healthy, you can beat it, Omicron is a systemic disease that requires
close management by a physician.
00:46:30
MK It’s
important what Abdi has just said because a lot of people ask us for
individual-level advice and it’s very difficult for us to sit here to give
individual-level advice because people are different. They have their age,
their underlying conditions, whatever it may be.
So, I just want to emphasise what Abdi has just
said, to speak to your physician. We issue, as he said, clinical guidance that
works with ministries of health and hospitals to outline what is the best
course of clinical care based on what people have, if they’re pregnant, if
they’re not, if they have underlying conditions.
I get a lot of text messages from friends and
family that says I have a family member or a cousin that’s having this. Always,
my advice is to speak to your doctor because we don’t know the full situation.
So, I just wanted to highlight that we cannot give individual-level advice in a
setting like this but please to talk to your doctor because every situation is
different.
AK Thank
you both. We’re coming slowly to an end and I have maybe a question or two
before we close. We received, actually, several questions today about Omicron
and children. What are the trends? What do we know? Then, there was a question
in particular, as you touched upon long COVID. What do we know about long COVID
in children? Is it possible and how often does it happen?
MK In
general?
AK Long
COVID in children.
00:47:56
MK With
regards to what we’re learning about Omicron, again, we’re still learning every
day something new about this. We know that children can be infected with SARS-CoV-2
virus whatever variant is circulating and this is certainly also the case of
Omicron, as well.
What we tend to see, when we see a new Variant
of Concern circulating, we tend to see trends in different groups based on
social mixing patterns. We saw this with Alpha, we saw it with Beta, we saw it
with Gamma, we saw it with Delta, and we see it with Omicron.
So, the groups that are out and mixing will have
higher rates of infection, just for the sheer fact that they’re in contact with
each other. We do see this among school-age children because children are back
at school. Children overall, and including with Omicron, tend to have less
severe disease compared to adults. That’s certainly the case.
More often they have asymptomatic infection,
meaning that they don’t have any symptoms at all. Those trends still continue
but we do see children requiring hospitalisations and there have been some
instances where we’ve seen hospitalisations increase in paediatric populations,
under five.
But, as we have seen Omicron circulate, we are
also seeing other respiratory pathogens circulate, so it complicates the
picture. We see RSV that is circulating, which tends to be a respiratory virus
that infects young children or younger children, and influenza is back.
00:49:23
Through our GISRS, through our Global Influenza
Surveillance and Response System, we are tracking influenza, as we have been
for decades, and in 2020/2021 influenza circulation was minimal if not wiped
out but we are now starting to see increasing trends again.
So, this will complicate pictures and speaking
as a mom of two young boys who always seem to have something, a runny nose or
something, not COVID-19 because we have access to tests here. We are very
fortunate for that. Maybe not RSV, maybe something else.
So, it does complicate the picture in terms of
what is circulating. I mention that particularly because of kids, because kids
tend to mix and it’s very difficult for children to wear masks and keep them
on, although we are seeing that they can. I’m not saying that they can’t. To
keep their physical distance is also quite challenging.
But, we’ve seen many, many schools around the
world and I do want to emphasise how important it is for children to be in
school, for their education, for their safety, for their wellbeing, and many
around the world have shown how they can open schools and keep schools open by
taken measures of having good surveillance in schools, having good
environmental controls, of disinfection, of improving ventilation, wearing
masks, making sure that the staff are vaccinated and, as well, keeping
transmission down in the communities. So, that there is a lot that we are
learning.
00:50:46
On long COVID, we do know that children can get
long COVID. Again, we don’t have a good estimate of what proportion of children
will have these longer-term effects. We know that it is possible. That’s not to
scare parents out there but, again, it’s just to re-emphasise that we need to
do what we can to reduce the spread. Abdi?
AM Maria,
you covered it very well. In some countries vaccination is recommended, so if
it is recommended please get the vaccine because the complication of COVID, it
is far much outweighed by the vaccine that you get. So, vaccines in those countries
that is recommended, please vaccinate children.
Children do get COVID. Unfortunately and sadly,
some of them tragically have died. The death of one child is sad for everybody,
for the whole community. So, where those countries have recommended these are
safe and effective, they have been studied, and children are receiving all the
immunisation, as I say, please get vaccinated to protect your loved ones.
However young they are, they can get it and the
lottery of how the body immune system is going to react, nobody can tell. We
have seen almost 800 children I think in the US who died suddenly. So, children
can get infected, they can get hospitalised, can get severe like anyone of us.
Luckily, the vast majority of them don’t end up dead but that 0.1 in a big
population is a big number, so please, please vaccinate your children where
those countries recommend it.
00:52:21
For us, we have our criteria as WHO, with 194
countries who want to vaccinate their 3.1 billion people and others who are the
highest risk, the healthcare workers, but in some countries in the world, it is
not the same situation. So, if you’re in a country where vaccination for
children is offered, please vaccinate your kids.
AK Thank
you both for very insightful answers today and to all our viewers for their
great questions. I will summarise the last one. It kind of came from different
people, so I will put it in one. What’s the way forward? Has Omicron reached
its peak? And, will we be freer once the spring comes? Would you like to start
with that one?
AM Yes,
we can be freer if we build population immunity and solidarity. Unfortunately,
what we have seen again and again is the community and brothers and everyone
going with politicisation and the nationalism has not helped that. If the ten
billion that has been equally distributed and everyone, there was march, this
hostility against this vaccine would have been different.
So, the virus will continue. We can’t predict
with the virus. Viruses will continue doing what they do but it is the human
behaviour that can change the trajectory. I’m a firm believer in the objective.
Recently, I saw a Japanese proverb someone shared. What happens when you sit on
a rock for three years? It eventually gets warm.
So, we need to sit tight. It will get better but
it’s not the time to relax. We need to get ready and improve that. So, three
years, that’s what the Japanese said. Maybe I am misquoting there but we will
get there and we will come there and we will talk about the days of Omicron and
the days of Delta, the five movies we watch after winning the series maybe, but
the only way out is we need to have a high level of population immunity and
that is only way I can see forward.
00:54:26
AK Thank
you, Abdi. Thank you for joining us today. It was really great to have you with
us. Maria, your thoughts for the end?
MK I
think we certainly can be in a better place in the spring, Northern Hemisphere
spring, but it is up to us. We’re looking at several different scenarios going forward.
In one of the scenarios, not mutually exclusive, but what we expect to see is
that this virus, the transmission will significantly reduce. With the tools
that we have, we can significantly reduce transmission, and this virus is well
on its way to becoming endemic at a global level. We’re not there yet, but it’s
well on its way.
We expect to continue to see flare-ups in
populations who are not well-protected, whether they haven’t had the vaccine,
they refuse the vaccine, and we will still see outbreaks of people who are not
well-protected.
We could go forward and start to see seasonal
patterns with SARS-CoV-2. It’s a respiratory pathogen, so we eventually expect
to see some kind of seasonal pattern similar to what we see with influenza but,
again, we’re not there yet. The virus is taking opportunities to spread and to
thrive and we are providing it plenty of opportunities to do so.
00:55:37
But, this may mean we will need some more
vaccines in the future and there are a lot of vaccines that are still in
development and underway and that research needs to continue, but the big
wildcard right now are the variants, and that is what makes us so uncertain
about the future.
Having said that, we have incredible hope and
you hear us always speak about this hope. We have to use the tools at hand and
we have them at hand. What we need to make sure is that we have the solidarity
around the world to get the tools in the hands of everyone, not just in what we
call the haves versus the have-nots. The divergence in which people around the
world have access to tools and those who have not is getting bigger and we need
to close that gap and that is up to us.
So, two sides of the equation. Increase
vaccination coverage among those who are most at risk in all countries, not
just in some countries. Use the vaccines that we have effective, appropriately,
morally correct, ethically correct and that will have a massive impact as we go
into this year.
As we continue to go into this year, we can take
the death and disease out of COVID-19 and by the spring we could see a
significant reduction in that, tangible, saving people’s lives now. But, we
also, on the other side of that equation have to drive transmission down.
If we don’t, we will continue to see variants
and the next one could be more severe. There’s no guarantee that variants that
will continue to emerge will be less severe. They may but we can’t really sit
back and just wait for that happen. It is up to us. It continues to be up to
us.
00:57:13
So, we are cautious, we are hopeful, we are
nervous but it’s up to what we do and every single person out there has a role
to play. I’m a broken record on this and I will continue to be because what we
also want people to feel is to be empowered, to be empowered to do something
about your life and the life of your loved ones.
Get vaccinated when it’s your turn. Continue to
adhere to measures to reduce your exposure. And, we do need governments to have
policies that make sense in their countries and we are there to support governments
in implementing those and adjusting those as we enter this third year of the
pandemic.
AK Thank
you so much, Maria. It was really a great pleasure to have you both today and I
really thank all our viewers for great questions, I think it was a great
variety, and for watching us from Kenya, Cameroon, DRC, Chile, Iran, India,
Nigeria, South Africa, Luxembourg, Zambia, Poland, Canada, US, Turkey and many
others. Please, stay safe, feel empowered. There’s a lot that each of us can do
and, until next week, please follow us on our social media channels or website
for any further updates on COVID and its Variants of Concern, including Omicron
and its sub-lineage, BA.2. Goodbye.
