  • MPV is a disease caused by a virus similar to smallpox, but symptoms from MPV are usually milder than those of smallpox. 
  • Infections with the type of MPV in this outbreak are rarely fatal, as 99% of persons are likely to survive, but symptoms can be painful.

MPV can spread to anyone through close, personal, often skin-skin contact including: 

  • Direct contact with MPV rash, scabs, or bodily fluids from a person with MPV. 
  • Touching objects, fabrics (clothing, bedding, or towels), and surfaces that have been used by someone with MPV. 
  • Prolonged contact with respiratory secretions.

MPV symptoms usually start within three weeks of exposure to the virus. 

  • Flu-like symptoms may occur initially and could include fever, headache, muscle aches and backaches, sore throat, cough, swollen lymph nodes, chills, or exhaustion. 
  • The characteristic rash will usually develop 1-4 days later, but a rash may develop with mild or no preceding symptoms. 
  • The rash may be located on or near the genitals or anus but could also be on other areas like the hands, feet, chest, or face. 
  • The rash will go through several stages, including scabs, before healing. 
  • The rash can look like pimples or blisters and may be painful or itchy. 
  • The rash may also be inside the body, including the mouth, vagina, or anus.
  • Avoid close, skin-to-skin contact with people who have a rash that looks like MPV. 
  • Do not touch the rash or scabs of a person with MPV. 
  • Do not kiss, hug, cuddle, or have sex with someone with MPV. 
  • Do not share eating utensils or cups with a person with MPV. 
  • Do not handle or touch bedding, towels, or clothing of a person with MPV. 
  • Wash your hands often with soap and water or use an alcohol-based hand sanitizer. 
  • At this time, the risk of MPV in the United States is believed to be low. MPV does not spread easily between people; however, anyone in close contact with a person with MPV can get it and should take steps to protect themselves. People who do not have MPV symptoms cannot spread the virus to others.

Please see the MPV Guide for the AU Community, which has detailed protocols and guidance for AU students, faculty and staff.

What Does MPV Look Like?

The rash evolves sequentially from macules (lesions with a flat base) to papules (slightly raised firm lesions), vesicles (lesions filled with clear fluid), pustules (lesions filled with yellowish fluid), and crusts which dry up and fall off.

The rash is often the most visible and distinct sign of MPX infection. Examples of the rash at various stages are seen above.
