MPX in Alameda County

Here is the latest information on MPX.

MPX pronounced /m·pox/ is formerly known as Monkeypox. MPX is a rare disease that is caused by infection with the MPX virus. MPX 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 MPX virus is not new, but there is a recent significant increase in reported cases where MPX 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 MPX for the general public is low. 

To learn about preventing infection, visit our FAQs webpage. If you are experiencing symptoms or were exposed to someone who is suspected or confirmed to have MPX, contact your health care provider right away to be connected to testing, and vaccine or treatment. If you don’t have a health care provider, email monkeypox@acgov.org.
