Texas Measles Outbreak Nears 150 Cases — Low Vaccination Rates Fuel Spread
Twenty people are in Texas hospitals. The state’s measles count now stands at 146 confirmed infections across nine counties. Those numbers, current as of February 28, 2025, mark a serious public health breach in a disease that was declared eliminated in the United States in 2000.
The outbreak has concentrated in areas with low vaccination coverage. That is the hard pattern public health officials see again and again. Measles finds the unvaccinated. It spreads fast. It lands people in hospital beds.
Dr. Jennifer Shuford, an infectious disease expert, put it bluntly: “Measles is a highly contagious and vaccine-preventable disease, and it’s essential that we take immediate action to prevent further spread.” The key word there is “highly.” One infected person can pass the virus to nine out of ten unvaccinated people they contact.
The Texas Department of State Health Services is working with local authorities to trace the outbreak’s source. They are also trying to contain it. Whether they can depends on how many people remain unprotected.
Measles does not announce itself dramatically at first. Ten to twelve days after exposure, symptoms begin: fever, cough, runny nose, inflamed eyes. Those look like a bad cold. Then the Koplik spots sometimes appear — small white marks inside the mouth, two or three days after symptoms start. Then the rash comes. It starts on the face. It spreads downward, covering the body. That flat red rash is the unmistakable signature of the disease.
Dr. Peter Hotez, a leading expert in vaccine development, stressed what should be obvious by now: “The measles vaccine is highly effective in preventing the disease, and it’s crucial that we maintain high vaccination rates to prevent outbreaks like this from occurring.” The measles, mumps, and rubella (MMR) vaccine is about 97 percent effective after two doses. It has been used safely for decades.
The stakes are concrete. Measles can cause pneumonia. It can cause encephalitis — brain swelling that can lead to deafness or intellectual disability. It can kill. Before the vaccine was introduced in 1963, the United States saw three to four million cases annually, with 48,000 hospitalizations and 500 deaths. Those numbers collapsed after widespread vaccination. Now, pockets of resistance to vaccination are bringing the disease back.
Texas is not an isolated problem. Outbreaks in recent years have hit New York, California, Ohio, and Minnesota. Each follows the same pattern: a traveler brings measles in from abroad, the virus lands in a community with low immunization rates, and it burns through susceptible people. The current Texas outbreak spans nine counties. It could easily spread further.
The virus itself is called morbilli. Its formal medical names include rubeola and English measles. None of those matter to the people coughing in hospital rooms. What matters is that a disease we know how to stop is moving again.
Health officials are not waiting. They are identifying cases, tracing contacts, urging vaccination. But the window for containment narrows with each new infection. Measles is airborne. It can linger in a room for up to two hours after an infected person leaves. You do not need to touch anyone to catch it.
What happens next in Texas will depend on how many people choose vaccination. The numbers so far — 146 cases, 20 hospitalized — are still small by historical standards. But they are growing. And in a highly mobile population, today’s Texas outbreak is tomorrow’s problem for another state.
