The Centers for Disease Control & Prevention is now echoing the controversial call for men who have sex with men to limit their sexual partners amid the monkeypox outbreak.

The agency made the call as part of new comprehensive monkeypox guidance issued on Friday, which lists “limit your number of sex partners to reduce your likelihood of exposure” as among several ways to reduce risk, with vaccination at the top of the list. “Vaccination is an important tool in preventing the spread of monkeypox,” the guidance says. “But given the current limited supply of vaccine, consider temporarily changing some behaviors that may increase your risk of being exposed.

These temporary changes will help slow the spread of monkeypox until vaccine supply is adequate.” The call to limit partners was previously made by the World Health Organization and has been controversial as observers say it may stigmatize sex among gay and bisexual men, who are disproportionately affected by monkeypox.
