Symptoms of this condition may include fever, muscle aches, and swollen lymph nodes.
Monkeypox is a rare illness, sometimes described as a milder form of smallpox, that is caused by a virus.
Monkeypox occurs mainly in the rain forest countries of central and west Africa. It was first discovered in laboratory monkeys in 1958. Blood tests of animals in Africa later found evidence of monkeypox infection in a number of African rodents. The virus that causes monkeypox was recovered from an African squirrel. Laboratory studies showed that the virus could also infect mice, rats, and rabbits. In 1970, the disease was reported in humans for the first time.
In June 2003, monkeypox was reported in prairie dogs and humans in the United States.
Monkeypox is caused by Monkeypox virus. The Monkeypox virus is within the family Poxviridae and the genus Orthopoxvirus. Other orthopoxviruses that cause infections in humans include:
Monkeypox transmission can happen either from animal to human or less commonly, from human to human.
