Resurgence of Measles Sparks Concern in the United States Amid Texas Outbreak
While generally uncommon in the United States, measles is generating increased apprehension among Americans due to a concerning rise in cases, particularly in rural West Texas.
Texas Measles Outbreak: Unvaccinated Child Dies
Tragically, an unvaccinated child succumbed to the virus last week amidst an ongoing outbreak involving nearly 200 confirmed cases. This incident marks the first reported measles fatality in the U.S. since 2015, according to the U.S. Centers for Disease Control and Prevention (CDC).
The CDC announced on Tuesday via social media platform X that it is “on the ground in TX,” confirming that federal assistance has been requested by the state to aid in the investigation and containment of the outbreak.
Understanding Measles: Key Facts and Prevention
Here’s essential information about measles and effective protective measures:
Measles Cases Beyond Texas
Although Texas is experiencing the highest number of measles cases in the nation this year, New Mexico has also reported 30 cases. However, the New Mexico health department has indicated no direct link to the Texas outbreak at this time.

Additional measles cases have been documented in Alaska, California, Georgia, Kentucky, New Jersey, New York, Pennsylvania, and Rhode Island, demonstrating a wider spread of the virus.
Defining Measles Outbreaks and Transmission
The CDC defines a measles outbreak as the occurrence of three or more related cases. In 2025, three clusters have already met the criteria for outbreaks. Within the U.S., measles cases and outbreaks are typically linked to individuals who contracted the illness while traveling internationally. The disease can then propagate, especially within communities where vaccination coverage is low.
Measles: A Highly Contagious Respiratory Illness
Measles is a respiratory illness caused by an exceptionally contagious virus. This airborne virus spreads readily when an infected individual breathes, coughs, or sneezes. Children are most frequently affected by measles.
“On average, a single infected person can transmit the virus to approximately 15 others,” explained Scott Weaver, director of a center of excellence for the Global Virus Network, a worldwide coalition of virology experts. “Very few viruses exhibit such a high rate of contagiousness.”
Measles Symptoms: Recognizing the Signs
Measles initially infects the respiratory system before disseminating throughout the body. Initial symptoms include:
- High fever
- Runny nose
- Cough
- Red, watery eyes
A characteristic rash is also a hallmark symptom of measles.
The Measles Rash: Progression and Appearance
The measles rash typically emerges three to five days following the initial symptoms. It begins as flat, red blemishes on the face and subsequently spreads downwards to the neck, torso, arms, legs, and feet. Upon the rash’s appearance, fever may escalate to over 104 degrees Fahrenheit, according to the CDC.
Measles Treatment and Management
There is no specific antiviral treatment for measles. Medical care focuses on alleviating symptoms, preventing secondary infections, and ensuring patient comfort during the illness.
Measles Immunity and Potential Dangers
Individuals who have recovered from measles develop lifelong immunity, health authorities confirm.
While measles is not typically fatal, severe complications can arise.
Measles Complications and Vulnerable Groups
Common complications associated with measles include ear infections and diarrhea. Alarmingly, approximately 20% of unvaccinated Americans who contract measles require hospitalization, according to the CDC. Pregnant individuals who are unvaccinated against measles face risks of premature birth or delivering infants with low birth weight.
Among children with measles, about 1 in 20 will develop pneumonia, the CDC reports. Furthermore, approximately 1 in 1,000 children with measles experiences encephalitis, a dangerous swelling of the brain, which can result in seizures, deafness, or intellectual disability.
Measles is fatal in “slightly less than 1% of cases, primarily in children,” stated Weaver. “Children are more likely to develop severe illness. Pneumonia and its complications are the usual causes of death in these cases.”
Measles Prevention: The MMR Vaccine
The most effective method for preventing measles is vaccination with the measles, mumps, and rubella (MMR) vaccine. The recommended immunization schedule includes a first dose for children between 12 and 15 months of age and a second dose between 4 and 6 years old.
“Prior to the introduction of the measles vaccine in the 1960s, nearly everyone contracted measles,” Weaver noted. “The vaccine was a revolutionary advancement and stands as one of the most successful vaccines in medical history.”
Extensive data supports the safety and efficacy of the MMR vaccine, as it has been utilized for decades, he added.
“Any measles outbreaks we are observing are readily preventable through increased community vaccination rates,” he emphasized. “Maintaining a 95% vaccination rate within the population would effectively prevent future outbreaks. Unfortunately, vaccination rates have fallen below this critical level in many areas of the country.”
Declining Vaccination Rates and Public Health Concerns
Vaccination rates have decreased across the nation since the COVID-19 pandemic. Most states currently have kindergarten vaccination rates below the 95% threshold necessary to ensure community protection against measles outbreaks.
Measles Vaccination Recommendations for Adults
Healthcare professionals are sometimes screened for measles antibodies and receive booster doses if needed, even if they received the standard two doses in childhood, Weaver mentioned.
Generally, adults with “presumptive evidence of immunity” do not require measles vaccination, according to the CDC. Criteria for presumptive immunity encompass:
- Written documentation of adequate vaccination history
- Laboratory confirmation of prior measles infection
- Birth before 1957 (indicating likely natural infection)
Furthermore, individuals documented to have received a live measles vaccine in the 1960s do not need revaccination, the CDC added. However, those vaccinated before 1968 with an inactivated (“killed”) measles vaccine, or those uncertain of the vaccine type received, should receive at least one dose of revaccination, the agency advises.
Weaver suggested that individuals at high risk of measles exposure who were vaccinated many years ago may consider a booster if they reside in an outbreak area. High-risk groups include household contacts of measles patients and those with underlying medical conditions that increase vulnerability to respiratory infections.
“I don’t believe everyone needs to rush to their doctors for a booster immediately if they received two doses as children,” he clarified. “If people would simply adhere to the standard vaccination schedule, these outbreaks would be entirely preventable.”
