HIV Awareness Campaign Yields Results in Tanzanian Village

None of the 2,500 out of 15,000 villagers in Rusaba Village, Kasulu District, Kigoma Region, tested positive for HIV this year between July and September. Local health workers had never come upon such results. They attribute it to an HIV/AIDS awareness campaign conducted by Tanzania Red Cross and Action Aid International, low interaction between villagers and outsiders, and close-knit family structures.

Depending on the size and diversity of the population tested, HIV infection rates can appear distorted. AIDSTanzania, for example, has tested in rural villages during our trips to the Arusha area. In one village, of 100 people tested there were zero positive tests. At face value this is great news. However, a number of factors could be at play: HIV-positive people who know of their infection are usually not going to get tested again; those who suspect they have HIV are afraid to come forward and get tested; and with only 100 tests available, tests go to the aware individuals who show up early because they are already thinking about HIV prevention.

Because the testing in Rusaba Village was of 2,500 of 15,000 people over a period of a few months, we can be confident that it was a representative sample of villagers. These results, and the influential HIV awareness campaign, are something to keep in mind as we work to prevent HIV, encourage testing, and spread education.
