34.1 Epidemiologic Review

34.1.1 Disease Information

Overview: Mpox is caused by an Orthopox virus that causes rash and other symptoms.

Symptoms: Rash on the hands, feet, face, chest, mouth or near the genitals. Other common symptoms include fever/chills, swollen lymph nodes, exhaustion, muscle aches and backache, headache, and flu-like respiratory symptoms (cough, sore-throat, and congestion). Symptoms range widely. Symptoms occur between 3-17 days post-exposure. A person is considered recovered once their rash is fully healed and a new layer of skin has formed.

Transmission: Close contact, including skin-to-skin contact or contact with saliva, respiratory secretions, or genital areas. It can also rarely be transmitted by contact with contaminated objects, fabrics, or surfaces. A person can transmit mpox until their rash has fully healed and a new layer of skin has formed.

Treatment: Treatment is supportive to help alleviate symptoms. In severe cases or cases likely to be severe, tecovirimat may be considered.

Prevention Receiving a full vaccination course is the best measure.

34.1.3 Outbreaks

Salt Lake County was part of a global outbreak of mpox related to intimate contact. Historically, most cases of mpox were from human interaction with infected rodents and sustained human infections were unique to this outbreak. This outbreak disproportionately impacted men who have sex with men (MSM). The first cases were in May, with cases peaking in August, and the outbreak resolving in December. The highest weekly case count was 15.

In response, SLCoHD delivered information and vaccines to populations at-risk of experiencing an outbreak, and the local outbreak ended.
