The number of mpox cases in 2024 is already nearly double the number of cases that were detected in all of 2023.
The most recent data from the Centers for Disease Control and Prevention (CDC) has recorded 582 cases of mpox, formerly known as monkeypox, across all U.S. states and territories in 2024 to date. In 2023, a cumulative 299 cases were detected across the entire year.
The Middle Atlantic region — New Jersey, New York, and Pennsylvania — is currently reporting the highest number at 185 cases.
Mpox surged in the U.S. during 2022 when cases spread through the social networks of men who have sex with men. In the U.S., more than 32,000 cases of mpox were detected that year along with 58 total deaths.
The outbreak subsided through outreach and awareness as well as the use of the two-dose smallpox vaccine Jynneos, though access to this shot was hindered at first by limited supplies and poor planning.
Symptoms of the virus are flu-like and include a characteristic painful rash. It is primarily spread through skin contact, but unwashed clothing and bedsheets of an infected individual can also be a vector of transmission.
