Know the Signs

People with MPX may first develop flu-like illness with fever, headache, muscle aches, exhaustion, and enlarged lymph nodes. A characteristic rash, which can appear like blisters or pimples in certain parts of the body, may occur a few days later. These blisters or pimples may be very painful. MPX may require hospitalization in rare instances. In some cases, no flu-like symptoms appear, and individuals only develop a rash. People with the virus may experience all or only a few of these symptoms. The illness may last for up to 2 to 4 weeks and usually resolves without specific treatment.

Slow & Prevent Spread

There are several measures that can be taken to prevent infection with MPX virus:

  • Avoid any physical contact like hugging, kissing, or sexual intimacy with people who have symptoms of MPX, including a rash or sores.
  • Talk to sexual partner/s about any recent illness. Be aware of new or unexplained sores or rashes on your body or a partner’s body, including on the genitals and anus.
  • Do not share eating utensils or cups with a person with MPX.
  • Do not handle or touch bedding, towels, clothing, or other fabrics that have been in contact with someone with MPX.
  • Wash hands often with soap and water or use an alcohol-based hand sanitizer.
  • Read the CDC’s latest information on safer sex, social gatherings and MPX.


If you have symptoms:

  • Reach out to a health care provider to get checked out. If you don’t have a provider or health insurance, visit a public health clinic near you.
  • Take a break from sexual and intimate contact as well as attending public gatherings.
  • Isolate from others you live with.
  • Wear a mask and cover rashes if needing to be around others and when visiting a health care provider.


Health care providers should use standard and recommended isolation precautions when caring for patients with suspected or confirmed MPX infection.
