Zambia: Superinfection seen frequently in heterosexual couples

Superinfection among heterosexual couples in sub-Saharan Africa may be surprisingly frequent, according to findings from Zambia presented on Tuesday at the 48th Interscience Conference on Antimicrobial Agents and Chemotherapy in Washington DC. Researchers from the Zambia Emory HIV Research Project presented evidence that 3 out of 34 people among heterosexual Zambian couples were superinfected during the time of the study.
