The News In a bid to stem the resurgence of sexually transmitted infections, the Centers for Disease Control and Prevention plans to recommend doxycycline, a widely used antibiotic, for use after an unprotected sexual encounter.
The antibiotic would be taken only by gay and bisexual men and transgender women who have had an S.T.I. within the previous year or who may be at risk for one.
The scientific evidence is too limited to recommend the strategy, called doxy-PEP, to all people who might be exposed to infection-causing bacteria during sex.
The agency released draft guidelines on Monday and plans to finalize them after a 45-day public comment period. Why It Matters: Rates of S.T.I.s are skyrocketing.
