Biology and epidemiology of transmission of STD pathogens, including HIV
Dr. Cohen’s research work focuses on the transmission and prevention of transmission of STD pathogens including HIV. Much of his work has been conducted at the research sites he and his group have developed in Lilongwe, Malawi and Beijing, China. Dr. Cohen and his coworkers have identified the concentration of HIV in genital secretions required for transmission of HIV ( NEJM 336:1072, 1997; AIDS 15: 621, 2001), and the effects of genital tract inflammation on HIV (Lancet 349: 1868, 1997).
