Zimbabwe is rare bright spot for AIDS in southern Africa

HARARE, Zimbabwe — In southern Africa for the past two decades, casual sex helped to fuel the worst epidemics of HIV and AIDS in the world. In Zimbabwe, however, fewer people are taking chances anymore, making this otherwise beleaguered nation an unlikely bright spot in Africa's battle against AIDS...

...Experts suggest that sex has become another casualty of the country's eight-year economic depression, which has shrunk the economy by nearly half. Few men have the money to support extramarital affairs or, for bachelors, the late nights on the town often required to woo a woman.

"You have to spend to get sex," said Richard Chimbiri, who writes a column on HIV for the Financial Gazette, an independent newsweekly. "Some guys would have four or five girlfriends if they could. But the economic situation and the risk of HIV — it's all conspiring to make people change their attitudes."
