Seroreactivity to human papillomavirus type 16 virus-like particles is lower in high-risk men than in high-risk women.

Seroreactivity to human papillomavirus type 16 (HPV-16) virus-like particles (VLPs) in men attending clinics for sexually transmitted diseases (STDs) in Denmark (n = 219) and Greenland (n = 88) was compared with seroreactivity in women attending the same clinics and was furthermore related to epidemiologic variables and concurrent HPV DNA detection. Risk factors for male seropositivity in Denmark were lifetime number of sex partners, a history of STDs, and sexual preference and in Greenland were ever having had syphilis and years at school. Although men reported significantly more sex partners, the mean seroreactivity was significantly lower in men than in women: 0.

Prevention of AIDS: free condoms to drug abusers in the Municipality of Copenhagen.

The slogan "safer sex" was presented in a questionnaire investigation carried out over an interval of 6 months among intravenous drug addicts (N = 116) attending three different outpatient clinics in Copenhagen. Despite this, many of the patients, who were mainly heterosexual and many of whom were HIV positive, continued to practice sexual and injection behaviors which exposed both them and others to HIV infection. Free condoms and advice have been offered as a part of the campaign against AIDS.
