Zimbabwe: Fighting past fears to treat TB

The World Health Organization (WHO) says that because of their weakened immune system, people living with HIV are less able to fight infection and are more likely to develop active TB.

Co-infection rapidly increases the mortality rate and untreated sufferers of both HIV and TB are the most infectious, posing the greatest risk to those around them.
