Collin County is warning about a measles exposure in Frisco earlier this week, amid an outbreak of cases in Texas.
In a Friday news release, Collin County Health Care Services said there was an exposure at a Walmart store, located at 16066 State Hwy 121, on Tuesday, April 29. The timing, they said, was between 1:30 p.m. and 6:30 p.m.
Walmart didn’t immediately respond to a comment request Friday night.

Anyone who visited the store during this time should monitor for symptoms until May 20, according to the news release. Symptoms could include fever, dry cough, runny nose, sore throat, inflamed eyes, skin rash, as well as small white spots with blueish-white centers inside the mouth.
The county also advised immunocompromised people or those who are unvaccinated and pregnant to immediately contact health care providers if they believe they were exposed to measles.
Measles is considered one of the most contagious viruses in the world. It spreads through the air when an infected person coughs, sneezes or simply breathes. Particles can linger in a room up to two hours after an infected person has gone.
The illness spreads mostly through unvaccinated people, as the two-dose measles-mumps-rubella vaccine is highly effective at preventing the illness.

Earlier Friday, the Texas Department of State Health Services reported that there have been 683 confirmed cases since the outbreak began in January.
Collin County also saw a confirmed measles case in a middle school student earlier in April — the first child case reported in the Dallas-Fort Worth area. Though it currently appears in the state public health department’s list of “other 2025″ cases, instead of being tied to the West Texas outbreak.
