Mpox (formerly known as monkeypox)

Providing the latest updates on mpox, including cases, vaccines, and prevention strategies.


Mpox (formerly known as monkeypox) is a viral disease. The virus is mostly spread through skin-to-skin contact. A pregnant person can also pass mpox to a fetus.

Mpox isn't a sexually transmitted infection. Anyone who's exposed to mpox can get it — but some groups of Philadelphians are more likely to be exposed. The 2022 outbreak of mpox was found more often in men and transgender people who had sex with men and/or who had multiple partners.

If you believe you've been exposed, or are at risk of exposure, call (215) 685-5488 to ask about vaccines.
