Mpox is a very rare disease caused by infection with the mpox virus. It is usually found in Central and West Africa and does not occur naturally in the United States. However, cases have recently been identified in the U.S.

While the state of emergency for the 2022 outbreak has been declared over, people should continue to take measures to protect themselves, get vaccinated, and get tested when needed. Those in high-risk situations should talk to their healthcare provider about treatment.

Knowledge of how the mpox virus spreads continues to evolve. 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.
