A woman in her mid-20s has tested positive for measles in Dallas County, Texas, sparking concerns of widespread exposure in one of the most populous counties in the U.S.
Vaccinated But Contagious
Despite being fully vaccinated, the woman was contagious between May 30 and June 7. During that period, she visited Lemma Coffee in Plano on May 31 and attended First Baptist Church on June 1. Health officials are now working to identify and alert anyone who may have been exposed.
First Case in County Amid Ongoing Outbreak
This is the first confirmed case in Dallas County during a broader Texas outbreak, which has already seen 744 infections and two child deaths since January. Across the U.S., more than 1,100 cases have been confirmed this year, with three reported deaths.
CDC Issues Travel Warning
The CDC has warned travelers about potential exposure to measles in airports, public transportation, and crowded events. It strongly recommends full vaccination before any international travel to reduce the risk of infection and community spread.
What to Watch For

Early symptoms of measles include a high fever, cough, runny nose, and white spots inside the mouth, followed by a red rash that spreads from the head down. In severe cases, measles can cause pneumonia or even death.
Vaccination Rates Falling Below Safe Levels
While the measles vaccine offers 97% protection, the country’s overall vaccination rate has dropped to 91%, below the 95% threshold needed to prevent outbreaks. A study by Johns Hopkins University warned that falling vaccination rates could bring back measles as a common U.S. illness.
Health Officials Urge Action
Dallas officials are urging residents who may have been exposed to contact their healthcare providers and watch for symptoms. The source of the woman’s infection remains unknown, and the case is considered isolated for now.
