Comparative Study
Number of sexual partners, condom use and risk of human immunodeficiency virus infection.
To analyse the relation between number of sexual partners, selected sexual habits and the risk of human immunodeficiency virus (HIV) infection. ⋯ The risk of HIV infection does not increase linearly with the number of sexual partners in this population. This is reasonable, as the prevalence of HIV infection in this population is essentially determined by drug use. Caution is needed in the interpretation of these results since the analysis of role of number of sexual partners in male intravenous drug users is impaired by low statistical power.
