Although hospital managers reported that occupational exposure is rare, among the study population we found five health workers who claimed to have had an exposure to blood that they thought might have put them at risk for HIV infection, either because of needle-sticks or blood that went to their eyes. They all informed us that ARV prophylaxis for prevention of occupational exposure is free of charge at an ARV site at district hospital. But only two of them took medication because the others turned out not to need prophylaxis after closer assessment of their exposure.
