WHO consolidated guidelines on tuberculosis. Module 1: prevention – tuberculosis preventive treatment
Publication year: 2020
About one fourth of the world’s population is estimated to be infected with the tuberculosis (TB) bacterium, and about 5–10% of those infected develop active TB disease in their lifetime. The risk for active TB disease after infection depends on several factors, the most important being the person’s immunological status. TB preventive treatment given to people at highest risk of progressing from TB infection to disease remains a critical activity to achieve the global targets of the End TB Strategy, as reiterated by the UN High Level Meeting on TB in 2018.
