07 July 2017: Every day, more than 1 million sexually transmitted infections are acquired worldwide, and each year an estimated 78 million people are infected with gonorrhoea . New data from 77 countries show that antibiotic resistance is making gonorrhoea much harder – and sometimes impossible – to treat.

31 January 2017 - Neonatal herpes is a rare but potentially devastating complication of genital herpes during pregnancy, which can cause brain damage, breathing problems, seizures and even death. Neonatal herpes infection can occur when an infant is exposed to herpes simplex virus types 1 or 2 (HSV-1 or HSV-2) in a woman’s genital tract during birth. For the first time, researchers from WHO, the University of Bristol, and the University of Washington have published in new estimates The Lancet Global Health that aim to evaluate the approximate global burden of this disease.

WHO launches new treatment guidelines for chlamydia, gonorrhoea and syphilis

30 August 2016: More than 1 million sexually transmitted infections (STIs) are acquired every day worldwide. STIs present a major burden of disease and negatively affect people’s well-being across the globe. Chlamydia, gonorrhoea and syphilis are three STIs which are all caused by bacteria and which can potentially be cured by antibiotics. Unfortunately, these STIs often go undiagnosed and due to antibiotic resistance, they are also becoming increasingly difficult to treat.

Global drug shortage may put pregnant women diagnosed with syphilis at risk

19 July 2016: Pregnant women who have been diagnosed with syphilis can be cured with an injection of benzathine penicillin, a type of antibiotic which can kill the bacteria and which can also prevent mother-to-child transmission of this infection (congenital syphilis). Newly published evidence shows however, that shortages of benzathine penicillin have been reported by countries where there is high number of pregnant women and infants infected with syphilis.

Mother-to-child transmission of syphilis decreasing but mortality and morbidity remain high

19 July 2016: Syphilis is a bacterial infection caused by the spirochete Treponema pallidum, and can be transmitted sexually or from mother to child during pregnancy. Left untreated, syphilis can lead to catastrophic fetal outcomes in the second or third trimesters of pregnancy. New 2012 estimates, based on 2008-2012 data, are now available, published in an open access Lancet article. The findings show that in 2012, an estimated 930 000 maternal syphilis infections caused 350 000 adverse pregnancy outcomes including 143 000 early fetal deaths and stillbirths, 62 000 neonatal deaths, 44 000 preterm or low weight births, and 102 000 infected infants worldwide.
