How it Spreads

2022 U.S. Monkeypox Cases

CDC is closely tracking cases of monkeypox recently detected in the United States. CDC urges healthcare providers in the U.S. to be alert for patients who have rash illnesses consistent with monkeypox.

Monkeypox spreads in different ways. The virus can spread from person-to-person through:

  • direct contact with the infectious rash, scabs, or body fluids
  • respiratory secretions during prolonged, face-to-face contact, or during intimate physical contact, such as kissing, cuddling, or sex
  • touching items (such as clothing or linens) that previously touched the infectious rash or body fluids
  • pregnant people can spread the virus to their fetus through the placenta

It’s also possible for people to get monkeypox from infected animals, either by being scratched or bitten by the animal or by preparing or eating meat or using products from an infected animal.

Monkeypox can spread from the time symptoms start until the rash has fully healed and a fresh layer of skin has formed. The illness typically lasts 2-4 weeks. People who do not have monkeypox symptoms cannot spread the virus to others. At this time, it is not known if monkeypox can spread through semen or vaginal fluids.
