Mpox in Alameda County

Mpox — pronounced /m·pox/ — is formerly known as Monkeypox. Mpox is a rare disease that is caused by infection with the Mpox virus. Mpox can cause fever, headache, body aches, swollen lymph nodes, and a rash. The rash typically begins as flat spots that turn into bumps that fill with fluid. Some people develop spots that look like pimples or blisters before having any other symptoms. The bumps eventually crust and fall off as they heal.

The Mpox virus is not new, but there is a recent significant increase in reported cases where Mpox is not commonly seen, including in the United States, California, and Alameda County.

While it’s good to stay alert about this new local epidemic, the current risk of Mpox for the general public is low.
