In the general population, 80% of new infections occur in people in monogamous relationships. According to Senegal's AIDS authority, among the newly infected, three-quarters of people engage in some high risk behavior. About one quarter of the newly infected engage in high risk behaviors themselves and about half of the newly infected have a partner who engages in high risk activities.[4] Because homosexuality is illegal in Senegal, many MSMs have long term female partners as well as male partners, so many women unknowingly have a partner who is in a high risk group.[4]
