Health officials are investigating two confirmed cases of measles, the first in Tarrant County in 17 years.
Both cases involve adults, one a female in her 30s and the second a male who had household contact with the woman.
Early indications are the woman was likely exposed during a trip to Orlando, Fla., in early March, said Dr. Anita Kurian, chief epidemiologist for Tarrant County Public Health.
Measles symptoms include fever, runny nose, cough and a reddish rash all over the body. Measles is transmitted through the air by breathing, coughing and sneezing. It is so contagious that any person who is exposed to it, and not immune, will probably get the disease.
Anyone with symptoms should contact their physician as soon as possible.
Measles is prevented with a vaccine. Children should get two doses; adults who might not have been immunized should contact their physician to see if they need to be vaccinated.
