The illness usually begins with the following symptoms:

  • Fever
  • Chills
  • Headache
  • Muscle aches or pains
  • Swollen lymph nodes (e.g., in the neck and groin)
  • Fatigue

Within 1 to 3 days after the onset of symptoms, individuals often develop a rash on their face, limbs (including palms of the hands and soles of the feet), genitals, and/or mucous membranes (such as the mouth or nose).

Most often, individuals will recover from a monkeypox infection without requiring treatment. Vaccination against smallpox can provide some protection against monkeypox. If you have been exposed to a confirmed or probable case of monkeypox, you may be eligible to receive a post-exposure dose of the Imvamune® vaccine.

If you have been exposed, and/or are experiencing any signs or symptoms of monkeypox, contact your healthcare provider for medical assessment.
