CDC is updating webpages with the term "mpox" to reduce stigma and other issues associated with prior terminology. This change is aligned with the recent World Health Organization decision.

2022 Outbreak Cases and Data

Beginning Monday, December 5, 2022, the data below will be updated once per week on Wednesdays.

At this time, data suggest that gay, bisexual, and other men who have sex with men make up the majority of cases in the current mpox outbreak. However, anyone, regardless of sexual orientation or gender identity, who has been in close, personal contact with someone who has mpox is at risk. Take steps to prevent getting mpox. If you have any symptoms of mpox, talk to a healthcare provider.
