WASATCH COUNTY, Utah — The Wasatch County Health Department has confirmed five measles cases among Wasatch High School students and is investigating two additional suspected cases, officials announced Saturday. Two of the confirmed cases involved vaccinated students.

Health officials said one or more infected students attended school or school activities while contagious. Potential exposures may have occurred at Wasatch High during school hours on Nov. 14, 17 and 18, and at a school play on Nov. 15. The district has notified families with a letter outlining guidance and precautions.

“We did have a wastewater test indicate the presence of measles in the community on November 6th, and with cases existing in other parts of the state, we weren’t surprised to see cases here,” health department director Jonelle Fitzgerald said. She added that the confirmed cases at the high school are not connected, suggesting additional cases may emerge in the community.

Measles is one of the most contagious viruses known. It spreads through the air when an infected person coughs or sneezes and can linger for up to two hours. Symptoms typically appear one to three weeks after exposure and may include a high fever, cough, runny nose, red eyes and a rash that begins on the face.

With Thanksgiving gatherings approaching, WCHD spokesperson Lana North urged residents to be cautious. “Please be aware that measles is around. Keep your friends and family healthy by staying home if you’re sick,” she said.

Health officials emphasized that vaccination remains the best protection. The MMR vaccine is 97% effective after two doses.

Families were advised of the following guidance:

Children 12 months or older who have not received their first MMR dose should be vaccinated as soon as possible.

A second dose provides full protection and may be given as early as 30 days after the first.

Children who have only received one dose and it was more than 30 days ago should schedule their second dose promptly.

“Receiving two MMR immunizations will give your child 97% protection against measles for life,” the department noted. Immunizations are available through the health department, local pharmacies and medical providers.

Anyone experiencing measles symptoms — especially unvaccinated individuals or those with known exposure — should contact a healthcare provider before visiting a clinic or emergency facility to reduce the risk of exposing others.
