About one third of the world’s population is infected with tuberculosis (TB) bacteria. Only a small proportion of those infected will become sick with TB.

People with weakened immune systems have a much greater risk of falling ill from TB. A person living with HIV is about 26 to 31 times more likely to develop active TB.

The Millennium Development Goal to reverse the tuberculosis epidemic by 2015 has been achieved. The WHO End TB Strategy, adopted by the World Health Assembly in May 2014, is a blueprint for countries to end the TB epidemic by driving down TB deaths and TB incidence.. It includes global impact targets to reduce TB deaths by 90% and to cut new cases by 80% between 2015 and 2030, and to ensure that no family is burdened with catastrophic costs due to TB.
