WOODSTOCK IL – The McHenry County Department of Health (MCDH) reports an outbreak of six (6) mumps cases at the McHenry County Corrections Facility.

The Health Department is working closely with the Illinois Department of Public Health (IDPH), McHenry County Correctional Facility, and U.S Immigration and Customs Enforcement (ICE) authorities. Infectious detainees are being isolated and exposed detainees are being quarantined. Signage and educational materials, made available by MCDH, have been provided to detainees, inmates, staff, and jail visitors.

According to Susan Karras, RN, Director of Public Health Nursing for MCDH, “Mumps is a contagious viral disease that spreads through saliva or mucus from the mouth, nose, or throat when infected people cough or sneeze. Sharing food or utensils also spreads the disease.” Karras added, “Mumps usually starts with fever, headache, muscle aches, tiredness, and loss of appetite. Then most people experience a swelling of their salivary glands, which causes puffy cheeks and a tender, swollen jaw. Symptoms usually appear 16-18 days after infection, but this period can range from 12-25 days. Persons with mumps should stay home until at least five (5) days after symptoms appear. Most people with mumps recover completely in a few weeks.”

Mumps is a vaccine-preventable illness. Vaccinated children and adults can occasionally become infected with mumps; however, the disease is less likely to be severe. MCDH encourages children and adults to be current with their immunizations. Children should receive the first dose of mumps-containing MMR vaccine at 12 to 15 months, and the second dose at four to six years. All adults born during or after 1957 should have one (1) dose of MMR. Adults at higher risk, such as university students, healthcare personnel, international travelers, and persons with potential mumps outbreak exposure should have documentation of two (2) doses of mumps vaccine or other proof of immunity to mumps. Persons born before 1957 are thought to be immune, since they were likely infected naturally.

In recent years, mumps outbreaks have occurred in schools, colleges, and camps, according to facts obtained from the Centers for Disease Control and Prevention (CDC). For more information, log onto or or call the MCDH Communicable Disease Program at 815-334-4500.
