A patient with HIV and tuberculosis (TB) wears a mask while awaiting consultation at the Ubuntu clinic in Cape Town's Khayelitsha township February 15, 2010. In South Africa, 5.5 million people live with HIV/AIDS ? more than in any other country - while 33 million people live with the disease worldwide. In Khayelitsha there is a saying, ?Living with HIV, dying from TB?. The weakened immune system leaves those infected vulnerable to infectious diseases like TB, which spreads easily in Khayelitsha?s poor living conditions and dense population. The TB incidence there is among the highest in the world. REUTERS/Finbarr O'Reilly (SOUTH AFRICA - Tags: HEALTH SOCIETY)
