Trends in Sexually Transmitted Infections Associated with the Doxycycline Post-Exposure Prophylaxis Guidelines in San Francisco.

ABSTRACT

ABSTRACT The San Francisco Department of Public Health was the first to issue guidance on the use of doxycycline for post-exposure prophylaxis against STIs in at-risk populations. We investigated the association between the issuance of these guidelines and rates of male rectal chlamydia, male rectal gonorrhea, and adult male syphilis.
