Mpox is a contagious rash illness caused by the mpox virus. It's primarily spread by close personal contact with someone who has mpox.
Mpox symptoms usually start within 3 weeks of exposure to the virus and are usually mild but can be severe. People with mpox often get a rash. For some people, the illness starts with flu-like symptoms that begin a few days before a rash appears.
While anyone can get mpox, most people infected with mpox have been gay, bisexual, or other men who have sex with men.
The best way to prevent mpox is by getting vaccinated.
