Mpox (formerly known as monkeypox) is a disease that is caused by a virus. Mpox spreads from person-to-person, mainly through direct physical contact with an infected person's:

  • Scabs / skin lesions or bodily fluids
  • Materials that are contaminated with the virus, such as bedding or clothes

Mpox can also spread through respiratory droplets, like through a cough or sneeze. However, the virus does not spread efficiently this way.


  • Fever
  • Chills
  • Sweats
  • Headache
  • Muscle aches and pain
  • Swollen lymph nodes, such as in the neck and groin
  • Fatigue
  • Sore throat
  • Rash that usually starts one to three days after other symptom onset. However, it can also be the first symptom. The rash can then turn into scabs and lesions.

Mpox is usually mild and typically goes away on its own within two to four weeks.

If you have been exposed to a suspected or confirmed case of mpox, monitor for signs and symptoms for 21 days. If you develop symptoms of mpox, self-isolate and contact your health care provider or Public Health.
