What is MPX (formerly known as Monkeypox):

MPX is a rare disease that is caused by infection with the MPX virus. MPX is a public health concern because the illness is like smallpox and can be spread from infected humans, animals, and materials contaminated with the virus. MPX is less transmissible and usually less severe than smallpox.¹

First identified in 1958 The MPX virus is not new and occurs primarily in Central and West African countries. However, 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 any emerging public health outbreaks, the current risk of MPX for the general public is low.

What are the symptoms of MPX:

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. ²

How does MPX Spread:

By very close and/or prolonged contact with someone with symptoms, including through:

    • Close physical/intimate skin-to-skin contact, including sex
    • Contact with contaminated materials (towels, bedding, and clothing)
    • Respiratory droplets spread by close and prolonged face-to-face interaction
