When Masks Are Recommended:

  • For people diagnosed with mpox
  • For those living with or caring for someone with mpox
  • For healthcare workers treating mpox patients
  • Not typically necessary for the general public

Mpox Transmission:

  • Primary spread through skin-to-skin contact
  • Can spread through contaminated objects and surfaces
  • Possible respiratory transmission during prolonged close contact
  • Contagious from rash appearance until complete healing

Common Symptoms:

  • Rash (often resembling pimples or blisters)
  • Fever and chills
  • Fatigue
  • Muscle aches
  • Headache
  • Respiratory symptoms
  • Swollen lymph nodes

Prevention Strategies:

  • Avoid contact with infected persons
  • Practice good hand hygiene
  • Clean and disinfect shared surfaces
  • For caregivers: use N95 or surgical masks when in close contact
  • Launder bedding and clothing of infected persons frequently
  • Follow safer sex practices if sexually active

When to Seek Medical Care:

  • If you develop a suspicious rash
  • After exposure to someone with mpox
  • If you have symptoms
  • To discuss vaccination if you're in a high-risk group

The virus typically resolves on its own within 2-4 weeks, but infected individuals should isolate until all lesions have healed completely and new skin has formed. While masks play a role in specific situations, the primary focus should be on avoiding skin-to-skin contact and maintaining good hygiene practices.
