Monkeypox (cont.)

Is monkeypox fatal?

Studies of human monkeypox in rural central and west Africa - where people live in remote areas and are medically underserved - have reported case-fatality ratios of as high as 10%.

How do people get monkeypox?

Monkeypox can spread to humans from an infected animal through an animal bite or direct contact with the animal's lesions or body fluids. The disease also can be spread from person to person, although it is much less infectious than smallpox. In human transmission, the virus is thought to be transmitted by respiratory droplets during direct and prolonged face-to-face contact. In addition, it is possible monkeypox can be spread by direct contact with body fluids of an infected person or with virus-contaminated objects, such as bedding or clothing.

Is there a treatment for monkeypox?

Currently, no treatment is available for monkeypox. Smallpox vaccine has been reported to reduce the risk of monkeypox among previously vaccinated persons in Africa. CDC is assessing the potential role of postexposure use of smallpox vaccine as well as therapeutic use of the antiviral drug cidofovir.
