This document summarizes the global burden of tuberculosis (TB) in 2011. Some key points:
- There were an estimated 8.7 million new TB cases and 1.4 million TB deaths in 2011. The majority of cases and deaths occurred in Asia and Africa.
- TB is a leading cause of death among people living with HIV, with 1.1 million new HIV-associated TB cases in 2011. 80% of the global TB/HIV burden is in Africa.
- There were an estimated 630,000 multi-drug resistant TB cases in 2011, with over 60% occurring in China, India, Russia and other countries.
- Women and children also face a large burden,

…El Cardenal tiene una salud frágil, consecuencia de una tuberculosis
que lo atacó cuando era un niño y le dejó secuelas: le falta la parte
superior alveolar del pulmón derecho… Sin embargo, físicamente es
fuerte. El mismo se esfuerza para no ser menos que los demás y practica
natación…
