Potential Measles Exposure Locations Released and Call Center Opened

Update Information as of August 25, 2026​

The Kane County Health Department (KCHD) is reporting a confirmed case of measles in a Kane County resident. The individual was unvaccinated against measles and is no longer infectious as of August 25, 2026.

Potential Exposure
KCHD has identified the following locations and dates where individuals may have been exposed to measles:

• Kaneland High School, 47W326 Keslinger Road, Maple Park, IL 60151 on August 18, 2026: Exposure may have occurred throughout the school day.
• Next Generation Pediatric Clinic, 107 S. McLean Blvd., Suite B, South Elgin, IL 60177 on August 21, 2026: Exposure may have occurred between 12:30 and 4 p.m.

Additional exposure information may be released as the investigation continues and information is confirmed.

What You Should Do If You May Have Been Exposed
If you were at one of the identified locations during the potential exposure period:

• Determine whether you are protected against measles. Evidence of immunity may include documentation of the recommended doses of MMR vaccine, laboratory evidence of immunity, or laboratory confirmation of previous measles infection. If you were born before 1957, you may also have evidence of immunity based on your birth year, although your healthcare provider may recommend vaccination depending on your circumstances.
• If you are unprotected and were potentially exposed, stay home and quarantine for 21 days from the date of potential exposure unless you can provide evidence of immunity. KCHD or another public health authority may provide specific quarantine instructions based on your circumstances.

• If you cannot locate your vaccination records, contact your healthcare provider, school, previous healthcare providers, or IDPH's vaccination records portal, Vax Verify. Your provider can discuss whether vaccination or blood testing is appropriate.

• Contact your healthcare provider if you are unsure whether you are protected against measles.
• Monitor for symptoms for 21 days after your potential exposure.
• If you develop symptoms and believe you may have been exposed to measles, call your healthcare provider before going to a medical office, urgent care or emergency department. This allows the healthcare facility to make appropriate arrangements to protect other patients and healthcare workers.

Know the Symptoms
Measles is a highly contagious respiratory illness that can spread easily from person to person. Symptoms may include:

• Fever
• Cough
• Runny nose
• Red or watery eyes
• Rash

The rash typically begins on the face and spreads to other parts of the body. Measles can cause serious complications, particularly in young children and other people at increased risk.

“We understand that news of a confirmed measles case may be concerning, particularly when there are potential exposures in schools and other community settings," said Michael Isaacson, KCHD Executive Director. “Our priority is identifying people who may have been exposed, making sure they receive timely guidance, and providing the community with accurate information as the investigation continues."

Protect Yourself Against Measles
The best way to prevent measles is vaccination. The MMR vaccine is highly effective at preventing measles, and two doses are approximately 97% effective.

KCHD encourages residents to review their vaccination records and talk with their healthcare provider if they are unsure whether they are protected.

If you are in need of vaccinations, contact:

• Your physician
• Your pharmacy
• Area health centers that often accept Medicare/Medicaid or offer free or sliding-scale services for low-income families
• The Kane County Health Department provides immunizations for children with Medicaid plans or who are uninsured or underinsured until their 19th birthday. We also provide vaccines for adults who are uninsured or underinsured. To learn more about eligibility, schedule an appointment, or obtain a referral, please call 630-208-3801.
