Notas del editor
- India and China do not have the highest rates of TB, but due to population numbers they contribute 40% of all TB cases globally
- 2009 (from 2010 report) All forms of TB, 9.4M cases, 1.7M deaths HIV-Associated TB: 1.1M cases, 380K deaths MDR-TB: 440K cases, ~150K deaths
- The number of cases is the same estimate as last year, but mortality estimates have dropped from 400,000 in 2009 to 350,000 in 2010.
- The geographical distribution of this tragedy is uneven, as sub-Saharan Africa has to suffer 80% of the burden, with several countries reporting over 10,000 deaths for the co-infection per year, and South Africa over 80,000. However, India has a large burden as well.
- The estimated annual TB incidence per 100,000 adults increases in a proportional way with the HIV prevalence in adults, 15-49 years of age. When HIV prevalence increases by 1%, the TB incidence increases by 26/100,000 per year.
- 2010 All forms of TB, 9.4M cases, 1.7M deaths HIV-Associated TB: 1.1M cases, 380K deaths MDR-TB: 440K cases, ~150K deaths
