On Mar. 4, 2025, the Texas Department of State Health Services reported an outbreak of measles in the South Plains region of Texas. At this time, 159 cases have been identified since late January. Twenty-two of the patients have been hospitalized. There has been one fatality in a school-aged child who lived in the outbreak area. The child was not vaccinated and had no known underlying conditions.

Measles is a highly contagious respiratory illness, which can cause life-threatening illness to anyone who is not protected against the virus. Measles can be transmitted by direct contact with infectious droplets or by airborne spread when an infected person breathes, coughs, or sneezes. People who are infected will begin to have symptoms within a week or two after being exposed.

Early symptoms include high fever, cough, runny nose, and red, watery eyes. A few days later, the telltale rash breaks out as flat, red spots on the face and then spreads down the neck and trunk to the rest of the body. A person is contagious about four days before the rash appears to four days after. People who could have measles should stay home during that period.

The best way to prevent getting sick is to be immunized with two doses of a vaccine against measles, which is primarily administered as the combination measles-mumps-rubella (MMR) vaccine. Two doses of the MMR vaccine are highly effective at preventing measles.
