10 facts on tuberculosis

Reviewed September 2018

About one quarter 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 20 to 30 times more likely to develop active TB.

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, incidence and eliminating catastrophic costs. It outlines 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 expenses due to TB.
