Mpox Case Counts (Placer & other counties) I Mpox FAQs
Since May 2022, there has been an uptick in mpox (monkeypox) cases in many countries around the world including the U.S., and here in California.
Mpox is spread by close physical contact with someone who has symptoms or by touching contaminated items, like clothing and bedding. It can cause flu-like symptoms and/or a distinct rash that can be bumpy or fluid-filled on the face, body, genitals, arms, and legs. It may also be limited to one part of the body.
Our current allocation of mpox vaccine is reserved for close contacts and is not available to the general public in Placer County at this time. If you have concerns about symptoms, please contact your healthcare provider. Currently, the risk of getting mpox is very low.

Some commercial laboratories are now offering Mpox testing. Specimens sent to commercial laboratories do not require Public Health approval for testing. However, if testing is being performed for mpox, Placer County Public Health requests a Confidential Morbidity Report (CMR) be sent via secure fax to: 530.886.2945, Attn: Mpox.
If commercial testing is not an option, you may collect specimens. However, Placer County Public Health must determine if epidemiological and clinical criteria is met and approve specimens for testing.
