California State – Monkeypox – General Information

About Monkeypox 

Monkeypox is a rare disease that is caused by infection with the monkeypox virus. Monkeypox virus belongs to the Orthopoxvirus genus, which includes the variola (smallpox) virus as well as the vaccinia virus, which is used in the smallpox vaccine. Monkeypox is of public health concern because the illness is similar to smallpox and can be spread from infected humans, animals, and materials contaminated with the virus. Monkeypox is less transmissible and usually less severe than smallpox.

Symptoms 

Monkeypox might start with symptoms like the flu, with fever, low energy, swollen lymph nodes, and general body aches. Within 1 to 3 days (sometimes longer) after the appearance of fever, the person can develop a rash or sores. The sores will go through several stages, including scabs, before healing. They can look like pimples or blisters and may be painful and itchy. 

The rash or sores may be located on or near the genitals (penis, testicles, labia, and vagina) or anus (butt) but could also be on other areas like the hands, feet, chest, and face. They may also be limited to one part of the body. 

People with monkeypox may experience all or only a few of these symptoms. Most with monkeypox will develop the rash or sores. Some people have reported developing a rash or sores before (or without) the flu-like symptoms. Monkeypox can spread from the time symptoms start until all sores have healed and a fresh layer of skin has formed. This can take several weeks.
