The HIV\/AIDS epidemic in the 1980s led to a surge of new syphilis cases and revealed the potentiation between HIV and syphilis, as evidenced by a shift in the natural history of neurosyphilis. In response, MSM revolutionised their sexual behaviour by implementing community-driven seroadaptive strategies to stem HIV transmission. The Centers for Disease Control in the US called for the elimination of syphilis in the late 1990s since the rates had fallen sharply but this effort was overtaken by a resurgence of global outbreaks among MSM in the 2000s, many of which were linked to methamphetamine use and sexual networking websites. Syphilis remains highly prevalent today, especially among MSM and individuals infected with HIV, and it continues to present a significant public health conundrum. Innovative syphilis prevention strategies are warranted. MSM engaging in high-risk behaviour such as condomless anal receptive intercourse, sex with multiple partners or recreational drug use should be routinely screened for syphilis infection; they should also be counselled about the limits of seroadaptive behaviours and HIV pre-exposure prophylaxis as they relate to syphilis transmission.<\/jats:p>","DOI":"10.1071\/sh14173","type":"journal-article","created":{"date-parts":[[2014,12,16]],"date-time":"2014-12-16T17:01:10Z","timestamp":1418749270000},"page":"96-102","source":"Crossref","is-referenced-by-count":49,"title":["Evolution of the syphilis epidemic among men who have sex with men"],"prefix":"10.1071","volume":"12","author":[{"given":"Marc M.","family":"Solomon","sequence":"first","affiliation":[{"name":"AGladstone Institutes of Virology and Immunology, 1650 Owens Street, 5th Floor, San Francisco, CA 94158, USA."},{"name":"BUniversity of California, San Francisco, CA 94143, USA."},{"name":"ECorresponding author.
