What is mpox?

Mpox is a virus that is spread through close physical contact. A majority of mpox cases in King, Pierce, and Snohomish Counties have been among men who reported sexual or close intimate contact with other men.  

The main symptoms of mpox are rashes and sores. The rash can look like bumps, pimples, and blisters that may be painful or itchy. Sores can look like lesions or ulcers. Rashes and sores may appear on one’s face, mouth, hands and feet, chest, genitals and anus.

People who get mpox may also develop flu-like symptoms:

  • Swollen lymph nodes
  • Fever
  • Exhaustion
  • Headache and muscle aches

However, the symptoms of mpox vary a lot. Many people with the infection never get a flu-like illness and the first thing they notice is a rash or sores. Some people report that their first symptom is rectal pain.

Symptoms usually start within 1-3 weeks of exposure to the virus. Mpox is rarely fatal, and most people recover in 2-4 weeks.

How is mpox transmitted?

Mpox is contagious, and spreads by:

  • Direct contact with mpox rash, sores, scabs, or the mucous membranes (mouth, anus) of a person with mpox
  • Sex and other intimate skin-to-skin contact.
  • Contact with objects, fabrics (clothing, bedding, or towels), and surfaces that have been used by someone with mpox.
  • Kissing and other face-to-face contact through respiratory droplets or oral fluids (saliva).

How can I protect myself from getting mpox?

  • Gay, bisexual, and other men who have sex with men, and transgender/non-binary people who have sex with men, or with other transgender/non-binary people, should get the first and second dose of the mpox vaccine. The second dose is available to anyone 28 days after receiving the first dose. 
  • People who have already received two doses of vaccine or who have had Mpox infection are considered immune to Mpox. Currently, Public Health - Seattle & King County and the CDC do not recommend that people receive booster doses of Mpox vaccine.

Note: Two doses of Mpox vaccine are thought to be approximately 80% effective in preventing clade II Mpox. It's believed that the vaccine will also protect against clade I Mpox, though data on how much the vaccine prevents clade I are very limited. Other prevention measures should still be considered.

Other ways to reduce your risk:

  • Decrease your number of sex and intimate contact partners.
  • Avoid sex parties and public sex venues, like bathhouses, and gatherings involving skin-to-skin contact.
  • Cover exposed skin while in dense crowds. 
  • Be mindful that activities, like kissing, can still spread mpox even at events where attendees are fully clothed and unlikely to have skin-to-skin contact.
  • Use condoms to help prevent skin-to skin contact, particularly if there are sores or rashes on the genitals or anus.
  • Talk to your partner about new or unexplained sores or rashes on your body, or your partner’s body, including on the genitals and anus, and other symptoms. Follow up with your provider if you suspect mpox or have questions.

What about testing and treatment?

If you or your partners feel sick, or have any rashes or sores:

  • Avoid sex, gatherings, and prolonged skin-to-skin or face-to-face contact.
  • Visit your doctor to get tested and treated for mpox.
  • Request an STD screening to rule out syphilis or other infections.

If you don’t have a doctor or health insurance, you can get tested and treated for mpox, and STDs, at the Public Health – Seattle & King County Sexual Health Clinic at Harborview, open M/W/TH/F, 7:30 am – 6:00 pm and Tuesday 9:30 am – 6:00 pm.​​​
