MPX (Monkeypox)

MPX is a rare disease caused by infection with the monkeypox virus. The monkeypox virus is part of the same family of viruses as variola virus, the virus that causes smallpox.

Currently there is a multi-national MPX outbreak with infections reported in all 50 U.S. states. In the current outbreak, hospitalization and death from MPX have been rare, but symptoms can be painful and affect daily activities.

What you should know about MPX

What are the signs and symptoms of MPX?

The most common symptom is a rash or sores that can look like pimples or blisters. These may be all over the body or just in certain parts, such as the face, hands or feet, as well as on or inside the mouth, genitals or anus. The rash and sores can be very itchy and painful, and sores in the anus or urethra can make it hard to go to the bathroom. Some people also have flu-like symptoms, such as sore throat, fever, swollen lymph nodes, headache, and tiredness.

If you develop a new or unexplained rash or other MPX symptoms, contact your healthcare provider.

Testing Information for MPX

If you have symptoms of monkeypox, you should see a health care provider for testing. If you do not have a provider, contact your local public health districtTesting for monkeypox is available when ordered through healthcare providers.  

How does MPX spread?

MPX can spread from person to person through direct contact with the infectious rash, scabs, or body fluids or by touching objects, fabrics (clothing, bedding, or towels), and surfaces that have been used by someone with monkeypox. It also can be spread by respiratory secretions during prolonged face-to-face contact or during intimate physical contact, such as kissing, cuddling, or sex.

MPX can spread to others from the time symptoms start until the rash has fully healed and a fresh layer of skin has formed. Anyone in close personal contact with a person with MPX can get it and should take steps to protect themselves.

How can MPX be prevented?

In the current outbreak, the majority of infections are occurring among gay, bisexual, and other men who have sex with men. However, anyone, regardless of sexual orientation or gender identity, who has contact with another individual with MPX is at risk. People more likely to get MPX may be eligible to receive a vaccine.

Other ways to prevent MPX include:

  •  Avoid close, skin-to-skin contact with people who have a rash that looks like MPX.
  • Avoid contact with objects and materials that a person with MPX has used.
  • Wash your hands often with soap and water or use an alcohol-based hand sanitizer, especially before eating or touching your face and after you use the bathroom.

Vaccine Information for MPX

JYNNEOS vaccine is approved for prevention of smallpox and monkeypox for people 18 years of age or older when administered subcutaneously. It is authorized for the prevention of monkeypox when administred intradermally or subcutaneously among people 18 years of age and older and for use in people less than 18 years of age when administered subcutaneously. It is the primary vaccine being used in the U.S. during this outbreak.

The JYNNEOS vaccine is given as a two-dose series, 28 days apart. It is recommended to get the second dose on time, but it may be administered up to y 35 days after the first dose. It is important to get both doses of JYNNEOS vaccine.

You are considered fully vaccinated against monkeypox 14 days after the second dose. Given the unknown effectiveness of vaccination in this outbreak, people who are vaccinated should continue to protect themselves from infection by avoiding close, skin-to-skin contact, including intimate contact, with someone who has monkeypox.

You should not get JYNNEOS vaccine if you had a severe allergic reaction after a previous dose of JYNNEOS. Talk to your healthcare provider if you have a history of an allergic reaction to the antibiotics gentamicin or ciprofloxacin or to chicken or egg protein.
