Washtenaw County Health Department Alerts Public to Second Local Measles Case

Washtenaw County Health Department is reporting a second case of measles and alerting the public to the possibility of exposure. This second case is in an adult without prior immunity to measles who was exposed to the Washtenaw case reported on March 3, 2024.

Anyone potentially exposed to this second case should monitor themselves for symptoms consistent with measles for 21 days after the exposure date. Since more than 72 hours have passed, it is too late for immediate vaccination to prevent infection.

The measles virus can live for up to two hours in the air, and individuals who were present at the following places at the specific times and dates listed may have been exposed:

Anyone present at one of the locations at the above times and dates should monitor themselves for symptoms for 21 days. If symptoms develop, call ahead before visiting a doctor, urgent care, or emergency room so they can take precautions to avoid exposing others.

“This situation illustrates why we work so hard to contain measles,” says Juan Luis Marquez, MD, MPH, medical director with Washtenaw County Health Department. “People without immunity from vaccination or a prior illness are very likely to become ill if exposed, and about 1 in 5 will require hospitalization.”

If vaccinated against measles, infection is unlikely. About 3 of every 100 vaccinated people exposed to measles will become ill if exposed to the virus according to the Centers for Disease Control and Prevention (CDC).

“This alert is more urgent for anyone potentially exposed to the confirmed case,” continues Dr. Marquez. “But it is also a critical reminder for everyone to check their vaccination status and confirm protection against measles.”

Measles

Measles is a highly contagious, vaccine-preventable disease that is spread by direct person-to-person contact, and through the air. Symptoms of measles usually begin 7-14 days after exposure, but can appear up to 21 days after exposure and may include:

• High fever (may spike to over 104˚F)
• Cough
• Runny nose
• Red, watery eyes (conjunctivitis)
• Tiny white spots on the inner cheeks, gums and roof of the mouth (Koplik Spots) two to three days after symptoms begin
• A rash that is red, raised, blotchy; usually starts on face, spreads to trunk, arms and legs three to five days after symptoms begin

If symptoms develop, call your doctor, urgent care, or hospital before seeking treatment.
