Sacramento County, California, officials say they have a suspected monkeypox case.
Public Health Officer, Dr. Olivia Kasirye, says the individual is doing well and is not hospitalized. The person has recently returned from Europe.
She says the county is waiting for final confirmation from the Centers for Disease Control and Prevention.
Monkeypox is a virus that originates in wild animals like rodents and primates, and occasionally jumps to people. It belongs to the same virus family as smallpox.
Health officials are still investigating, but a top adviser to the World Health Organization said this week that the leading theory is that monkeypox was likely spread after sexual activity at two recent raves in Europe.
