Editors choice: Worsening Epidemic of HIV and Syphilis Among Men Who Have Sex With Men in Jiangsu Province China

摘要

>Background. Epidemics of human immunodeficiency virus (HIV) and syphilis among men who have sex with men (MSM) are major public health concerns in most parts of China. A dearth of information regarding the current trend of HIV in this hard-to-reach population in several regions including Jiangsu, coupled with the reemergence of syphilis, calls for an effort to understand the dynamics of the dual epidemic in this province.>Methods. To estimate the occurrence and burden of these 2 sexually transmitted diseases and the distribution of their potential sociobehavioral correlates among MSM in Jiangsu, 2 cohort studies were conducted in Yangzhou and Changzhou cities.>Results. Among 839 participants, 48% were married, 51.7% had sex with women in the last 6 months, and 25.5% did not use condoms during their last anal intercourse. The observed incidence of HIV was 13.59 and 12.62 and that of syphilis was 7.33 and 13.25 per 100 person-years among the participants of Yangzhou and Changzhou, respectively. The baseline prevalence of HIV and syphilis was 16.0% and 29.9% in Yangzhou and 13.6% and 14.9% in Changzhou, respectively.>Conclusions. Considerably high incidence and prevalence of HIV and syphilis among participants and their potential bridging role in transmitting these infections to the general population in Yangzhou and Changzhou cities calls for urgent effective intervention strategies.
