Oak Park Health Department announces first presumptive case of MPV

July 26, 2022 – The Oak Park Health Department announced today the first reported presumptive case of monkeypox virus (MPV) in an Oak Park resident.

Based on initial epidemiologic characteristics, health officials consider this a probable MPV infection. Confirmatory testing for MPV is pending at the Centers for Disease Control and Prevention (CDC).

While MPV is a rare disease and does not spread easily between people without close contact, health officials urge the general public to be aware of the small but growing number of cases that have been identified. The threat of MPV to the general U.S. population remains low.

The Oak Park resident who contracted the presumptive MPV case remains isolated, and their close contacts are being identified by the Oak Park Health Department and will be offered post-exposure vaccination per the CDC and Illinois Department of Public Health recommendations.

MPV is a rare, but potentially serious, viral illness which belongs to the orthopoxvirus family. Infection typically begins with flu-like symptoms and swelling of the lymph nodes and progresses to a rash on the face and body.

Symptoms of MPV can include fever, headache, muscle aches and backache, swollen lymph nodes, chills, exhaustion and a rash that looks like pimples or blisters that appear on the face, inside the mouth and on other parts of the body, like the hands, feed, chest, genitals or anus.

Transmission occurs through close physical contact with body fluids, monkeypox sores, items that have been contaminated with fluids or sores (clothing, bedding, etc), or through respiratory droplets following prolonged face-to-face contact. This includes anyone with prolonged skin-to-skin contact and bodily fluids, such as through crowded settings or sexual contact. Anyone who has been in close contact with someone who has monkeypox is at risk.

More information about MPV is available on the Village website at The page includes information about ways to protect yourself and what to do if you contract the virus.
