Monkeypox is caused by the monkeypox virus, a member of the Orthopoxvirus genus.  It is usually a self-limited disease with symptoms lasting two to four weeks.  It is transmitted by direct skin-to-skin contact with someone who has the monkeypox rash (or scabs) or through materials contaminated with the virus, such as clothing, bedding, towels, or surfaces.
