Chronic hepatitis C can result in serious, even life-threatening health problems like cirrhosis and liver cancer. To learn more about Hepatitis C, click HERE.

Mpox is a viral illness closely related to smallpox, but which causes much less severe disease. Person-to-person transmission of the virus in some countries, including the United States, is fairly new. Mpox usually starts with symptoms like fever, headache, sore throat, swollen glands, and fatigue followed by rash. Not everyone with mpox will develop and show these symptoms; some may only develop a rash. The risk to the general public for mpox is low. Currently, a high proportion of cases are occurring among people who identify as gay and bisexual men. It is important that those at high-risk are aware of mpox and the steps they can take to reduce their risk of infection.  Click HERE to learn more.  


There is a vaccine for mpox, however supply is limited. St. Louis County Public Health is working with the Minnesota Department of Health and our local healthcare systems to distribute and administer vaccine to individuals recommended for vaccination. To learn more about who is recommended, click HERE.
