Syphilis case-finding in an Australian men's sauna club

Area of Science:

• Public Health
• Epidemiology
• Infectious Diseases

Background:

• Syphilis remains a significant public health concern, particularly within high-risk populations.
• Asymptomatic infections pose a challenge for disease control due to lack of early detection.
• Sauna clubs frequented by homosexual men represent a key venue for targeted screening.

Purpose of the Study:

• To assess the prevalence of syphilis among homosexual men attending a popular sauna club in Melbourne.
• To evaluate the effectiveness of serological testing in identifying asymptomatic syphilis cases.
• To determine the incidence of new syphilis infections within this population.

Main Methods:

• A 12-month survey involving 623 volunteers from a Melbourne sauna club.
• Serological blood tests for syphilis conducted on all participants.
• Follow-up investigations for individuals with positive test results and no prior syphilis history.

Main Results:

• A total of 114 (18.3%) participants tested positive for syphilis.
• Thirty-four (5.4%) had positive results with no prior syphilis history.
• Follow-up identified 17 new syphilis cases (2.7% incidence) among those with no prior history.

Conclusions:

• Blood testing at homosexual male sauna clubs is a highly productive method for detecting asymptomatic syphilis.
• This screening strategy is cost-effective for identifying individuals at high risk of infection.
• Targeted screening in such venues is crucial for syphilis control and prevention efforts.
