UNAIDS Official Visits Zimbabwe Amid 'Moderate' Drug Shortage Columbus Mavhunga HARARE, ZIMABABWE - A top UNAIDS official is in Zimbabwe as the country faces a moderate shortage of the anti-retroviral drugs that stop the progress of the disease. The situation is bad for HIV-positive Zimbabweans, but worse for prisoners living with the virus who say they are struggling to get treatment for opportunistic infections. Zimbabwe's maximum security prison is overcrowded, officials say, and that is putting a strain on resources, including medicines for inmates who have HIV, the virus that causes AIDS. .
