A recently released national TB survey in Tanzania showed that the disease was more prevalent in rural areas than urban, and affected more men than women. The number of TB patients increased from 62 per 100,000 in 1982 to 261 per 100,000 in 2011, and 295 per 100,000 in 2012. This made Tanzania one of the 22 countries with the highest number of TB cases, as listed by the World Health Organization. In rural areas, the number of patients is 316 per 100,000; the rate for men is 410 per 100,000, compared to the rate of 207 per 100,000 for women. Dr. Blasdus Njako, National TB and Leprosy Programme acting manager, blamed lack of education and health centers, and long distances to health centers for the high rate in rural areas and noted that his agency was working to send specialists to run screening campaigns in the remote areas of the country.
