2. Epidemiology

There is no evidence that people living with HIV are more likely to acquire TB infection in comparison with HIV negative people at the same level of exposure. However, whereas in patients without HIV, who are latently infected with TB, the risk of developing active TB in a life-time is about 10%this risk is increased to 10% per year for patients with HIV.

8.6 million people developed TB in 2012, and an estimated 13% (1.1. million) were HIV positive. Number of HIV positive people dying from TB has been reducing since 2003, but still reached 320 000 deaths in 2012. The prevalence of HIV co-infection among TB patients is the highest in the African Region.

The global TB incidence in 2012 was 122 cases per 100,000 population, with most cases occurring in Asia (58%) and Africa (27%). In addition, according to the WHO report 450 000 patients had MDRTB in 2012, among which 170 000 died.

For this section we have used the data from the Global Tuberculosis Report 2013, WHO.

  • Identify your country on the map and estimate the TB incidence.
  • What is the TB incidence for your country?
  • If it is higher or lower than other countries explain what the reasons are for the difference in your country?
