Mpox (formerly known as monkeypox) is a viral disease that usually spreads from animals to humans, though the animals that spread it (such as certain rodents and monkeys) are not found in Canada. Mpox can also spread from person-to-person, mainly through direct physical contact with an infected person's:

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

Mpox can also spread through respiratory droplets. However, the virus does not spread efficiently this way.


  • Fever
  • Chills
  • Headache
  • Muscle aches and pain
  • Swollen lymph nodes, such as in the neck and groin
  • Fatigue
  • Rash that usually starts one to three days after the symptom onset. 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, immediately self-isolate and contact your healthcare provider.
