During 33 screening sessions in Denver gay steambaths, 48 of 419 (11.5 per cent) men were found to have asymptomatic gonorrhea and six (1.4 per cent) had early latent syphilis. Questionnaires were administered to 160 men who reported a mean of 7.9 different male sex contacts per month. Female sex contacts were also reported by 30 per cent. The respondents used the baths an average of 2.2 times per month, having an average of 2.7 different sex contacts per visit, 84 per cent of whom were not previously known to the respondent. Gay steambaths are productive locations for detecting asymptomatic gonorrhea and syphilis.
