Community members and staff who visited the store and are not fully vaccinated against measles should watch for signs or symptoms of infection.

WESTERVILLE, Ohio — Franklin County Public Health is warning the public about a potential measles exposure at a CVS store in Westerville earlier this week. 

Health officials said someone with a confirmed case of measles visited the store located at 620 S. Cleveland Ave. between 9:30 a.m. and 12:30 p.m. on Tuesday. 

The health department noted that those who are fully vaccinated have a very low risk of getting sick, but community members and staff who visited the store and are not fully vaccinated against measles should watch for signs or symptoms of infection until April 7. 

Symptoms of measles include fever, rash, cough and red, watery eyes. The rash usually lasts from five to six days and begins at the hairline before moving down the body. Complications can include ear infections, diarrhea, pneumonia and brain inflammation.

Those who develop symptoms should stay home and contact their health provider, the health department said. 

Measles mainly spreads through the air after a person with measles coughs or sneezes, health experts say. 

The U.S. has been considered measles-free since 2000, meaning that enough of the country’s population is vaccinated that widespread outbreaks are prevented. However, the rising number of unvaccinated people in the country could threaten that status. Last month, the Ohio Department of Health warned the public about a potential exposure to measles at John Glenn Columbus International Airport.

According to the Centers for Disease Control, two doses of the MMR vaccine are about 97% effective at preventing measles, while one dose is about 93% effective. 

Last year, Ohio had 45 reported cases of measles, according to the state’s department of health. In 2024, the state had 45 cases. 

Across the United States, 1,362 confirmed measles cases have been reported in 2026 as of March 12, according to the CDC. In 2025, a total of 2,284 cases were confirmed across the country.Â
