This study aimed to assess the prevalence of amoebiasis among patrons visiting gay saunas in Taiwan.
A cross-sectional survey was conducted using questionnaire interview and indirect hemagglutination assays and specific Entamoeba histolytica antigen assays of blood and rectal swab specimens, respectively, among patrons visiting 10 gay saunas between September 2006 and December 2006.
During the three-month study period, 208 blood and 120 rectal swab specimens were tested for E. histolytica infection. Amoebiasis was detected among 3.8% and 3.3% of the patrons by serologies and antigen assays, respectively. During the latest sexual encounter, more than 70% of the patrons had oral-anogenital sex, and only 20% used condoms during oral-anogenital contact.
Our findings suggest that there is a potential risk of E. histolytica transmission among the patrons visiting gay saunas who do not practise safe sex consistently in Taiwan.
本研究旨在评估台湾光顾同志桑拿浴室的人群中阿米巴病的患病率。
于2006年9月至2006年12月期间，对光顾10家同志桑拿浴室的人群进行横断面调查，采用问卷调查以及分别对血液和直肠拭子标本进行间接血凝试验和溶组织内阿米巴特异性抗原检测。
在为期三个月的研究期间，共检测了208份血液标本和120份直肠拭子标本的溶组织内阿米巴感染情况。通过血清学检测和抗原检测，分别在3.8%和3.3%的人群中检测到阿米巴病。在最近一次性接触中，超过70%的人群有口-肛门性行为，而在口-肛门接触期间只有20%的人使用了避孕套。
我们的研究结果表明，在台湾，光顾同志桑拿浴室且未始终坚持安全性行为的人群中存在溶组织内阿米巴传播的潜在风险。
