What is the relationship between HIV and TB?
Together, HIV and TB are a deadly combination, each disease making the other disease progress faster. HIV makes the immune system weak, so that someone who is HIV-positive and also infected with TB becomes much more likely to get sick with TB than someone infected with TB who is HIV-negative. In Ethiopia, TB is the leading cause of death among people who have HIV. HIV is the single major reason why there has been such a large increase in cases of TB over the past decade.
