描述----------Description----------
Researchers in Kenya identified a cohort of more that 1,000 prostitutes who were known to be a major reservoir of sexually transmitted diseases in 1985. It was determined that more than 85% of them were infected with human immunodeficiency virus (HIV) in February, 1986. The researchers identified men who acquired a sexually-transmitted disease from this group of women after the men sought treatment at a free clinic. The data frame contains data on the subset of those men who did not test positive for HIV on their first visit and who agreed to participate in the study. The men are categorised according to whether they later tested positive for HIV during the study period, whether they had one or multiple sexual contacts with the prostitutes and whether they were circumcised.
