Measles Outbreak Spreads to 25 States: What Parents Need to Know

The measles outbreak is no longer confined to West Texas—it’s spreading throughout the US. As of mid-April, measles cases have been reported in 25 states, according to the CDC, including Alaska, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Indiana, Kansas, Kentucky, Maryland, Michigan, Minnesota, New Jersey, New Mexico, New York City, New York State, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont and Washington.

The multi-state spread most likely brought on by travel marks the widest spread of the virus in recent years. This outbreak has already surpassed the total number of measles cases in 2024, with the largest cluster still tied to the orginal outbreak centered in Texas.

That outbreak, which began in Gaines County, has now grown to 800 confirmed cases. While the majority of the cases are still happening in Texas with 597 cases, multiple states are reporting new cases weekly. Health officials warn that the situation remains fluid—and that low vaccination rates in some communities may fuel further spread.

Measles is a highly contagious viral infection that spreads through coughing, sneezing and even lingering airborne particles. It often starts with cold-like symptoms—fever, cough, runny nose and red, watery eyes—before a telltale red rash appears. While it may seem mild at first, measles can lead to serious complications, especially in young children, including pneumonia, brain swelling and in rare cases, death.

Most infections involve children ages 0 to 19, including 249 cases in children under 5 and 304 cases in those aged 5 to 19. Eighty-five people have been hospitalized, and two deaths have been confirmed with one under investigation. CDC data shows that only 3% of cases this year have been reported in people who have gotten one or two doses of the measles-mumps-rubella (MMR) vaccine.

Low Vaccination Rates Fueling the Outbreak

Health officials warn that the number of cases may continue to rise, especially given low vaccination rates in the area. Nearly 1 in 5 incoming kindergartners in Gaines County weren’t vaccinated against measles for the 2023-24 school year. Other affected counties—Lynn, Lubbock, and Yoakum—also fall short of the 95% vaccination rate recommended by the US Department of Health and Human Services to prevent outbreaks. Nationally, the US has failed to meet this benchmark for four consecutive years.

In response, local health departments are hosting free vaccination clinics. The South Plains Public Health District, which covers Gaines County, has administered more than 100 Measles Mumps and Rubella (MMR) vaccines and expanded clinic hours to seven days a week.

Why Measles Is Making a Comeback

Measles was nearly eradicated in the US by the 1980s thanks to widespread vaccination. Before the measles vaccine was introduced in 1963, an estimated 3 to 4 million Americans contracted the virus annually. Vaccination efforts led to a 99% drop in cases, but recent years have seen a resurgence.

While the CDC says the risk of widespread outbreaks remains low due to overall population immunity, pockets of low vaccination coverage leave some communities vulnerable. To prevent future outbreaks, the CDC urges parents to ensure their children are fully vaccinated.

How to Protect Your Family

The MMR (measles, mumps, rubella) vaccine remains the most effective defense. The CDC recommends children receive the first dose between 12 and 15 months of age and a second between 4 and 6 years old. Two doses are about 97% effective at preventing measles.

If you live near an affected area or your child isn’t up to date on their vaccines, contact your pediatrician or local health department. As the outbreak grows, health officials emphasize that vaccination and community awareness are key to stopping the spread of this preventable disease.
