Incidences of Tuberculosis-Worldwide

e - $10.99

The World Health Organization (WHO) estimates that the largest number of new TB cases in 2004 occurred in WHO's South-East Asia Region, which accounted for 33% of incident cases globally. However, the estimated incidence per capita in sub-Saharan Africa is nearly twice that of the South-East Asia Region, at nearly 400 cases per 100 000 population.

It is estimated that 1.7 million deaths resulted from TB in 2004. Both the highest number of deaths and the highest mortality per capita are in the WHO Africa region, where HIV has led to rapid growth of the TB epidemic, and increases the likelihood of dying from TB.

In 2004, estimated per capita TB incidence was stable or falling in five out of six WHO regions, but growing at 0.6% per year globally. The exception is the African region, where TB incidence was still rising, in line with the spread of HIV. However, the number of cases notified from the African region is increasing more slowly each year, probably because the HIV epidemics in African countries are also slowing. In Eastern Europe (mostly countries of the former Soviet Union ), incidence per capita increased during the 1990s, but peaked around 2001, and has since fallen.

Incidence - new cases arising in given period; prevalence - the number of cases which exist in the population at a given point in time.
bSmear-positive cases are those confirmed by smear microscopy, and are the most infectious cases. Pop indicates population.
