Measles Updates: 800 Cases In U.S. As Illness Spreads To Louisiana, Missouri And Virginia

Louisiana, Missouri and Virginia this weekend reported their first measles cases of the year, not long after the Centers for Disease Control and Prevention reported 800 confirmed cases of the illness in the U.S. so far in 2025, making the announcement as the highly contagious illness reached at least half of the states in the country—though most cases remain in Texas.
Health officials in Louisiana, Missouri and Virginia confirmed their first measles cases of the year Friday and Saturday, with all three of the respective cases being linked to international travel.
The Louisiana resident is an unvaccinated adult, while the Missouri and Virginia residents are both children with unverified vaccination statuses.
Excluding the cases from the three states, there have been 800 confirmed cases of measles across 25 states so far this year, according to the latest update from the CDC on Friday, far surpassing the 285 measles cases reported in the entirety of 2024 (the CDC does not provide data on how many cases are actively infectious).
The Texas Department of State Health Services reported its measles outbreak had grown to 597 cases as of Friday, with 62 of the patients having been hospitalized and two school-aged children confirmed dead from the illness.
Less than 30 of the confirmed cases are estimated to be actively infectious, according to Texas health officials.
The Texas health department said 22 of the cases were in vaccinated people, with the remainder of the 575 sick patients being unvaccinated or having an unknown vaccination status.
In New Mexico, which has the second-highest number of measles cases in the country, Lea County is home to 59 of the state's 63 confirmed cases, and is about 47 miles from Gaines County, Texas, where the majority of Texas' measles cases have been detected.
The Kansas Department of Health and Environment reported 37 confirmed cases as of Friday, and Jill Bronaugh, the department's communications director, previously told Forbes genetic sequencing of one case is 'consistent' with a link to outbreaks in Texas and New Mexico.

There have been 371 measles cases confirmed in Gaines County, a rural area about an hour-and-a-half west of Lubbock. Cases have reached double digits in Terry County (52), Lubbock County (42), Dawson County (24), Yoakum County (19), Lamar County (11) and Cochran County (12), with a total of 25 Texas counties confirming cases of the illness.
An eight-year-old girl died in Lubbock, Texas, of 'measles pulmonary failure' after contracting the disease, the New York Times first reported, with the hospital where she died, UMC Health System, confirming the death to media outlets, noting the child was unvaccinated and did not have any underlying health conditions. An unvaccinated six-year-old also died of measles in February, marking the first death from measles in the U.S. in a decade.
Some 219 of the cases have been among people aged five to 17, while 182 cases were among children younger than five and 172 were reported among adults aged 18 and above. The ages of 24 patients have not been stated.
Outside of Texas, New Mexico, Kansas and Ohio, anywhere from one to nine cases have been confirmed by the CDC in Alaska, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Indiana, Kentucky, Maryland, Michigan, Minnesota, New Jersey, New York City, New York State, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Vermont, and Washington.
Symptoms of measles include a fever, rash, cough, fatigue, runny nose and red eyes. The symptoms do not appear until 10 to 14 days after someone is exposed to the virus and can appear as late as 21 days after exposure.
Measles is highly contagious and can spread from one person to nine out of 10 people close to them, according to the CDC, which notes a person infected with measles can spread it to others four days before through four days after the rash appears. Measles can spread through coughing, sneezing and infected surfaces and linger in the air and on surfaces for up to two hours after infected people leave a given area.
People infected with measles should isolate for four days after they develop a rash, with the day of rash onset being considered day zero.
Yes, and it is highly effective and safe, according to the CDC. The measles, mumps, and rubella vaccine, which has been available for over half a century, is about 97% effective at preventing measles with the standard two doses and 93% effective with one dose. The vaccine is typically given to people when they are children, with one dose administered between 12 to 15 months and another administered between four to six years old. The vaccine generally provides long-term or lifelong protection. There is no problem with getting the vaccine if you are an adult unsure of their vaccination status, Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University Medical Center, told NPR. Adults born after 1957 and vaccinated before 1968 should consider getting revaccinated, NPR reported, noting early measles vaccines are not as effective.
After initially claiming the measles outbreak was 'not unusual,' Kennedy changed his stance and considered it 'serious,' saying in a since-removed March 3 statement the outbreak 'is a call to action for all of us to reaffirm our commitment to public health.' On April 6, Kennedy said the 'most effective way to prevent the spread of measles is the MMR vaccine.' In a separate follow-up post, the HHS leader touted 'two extraordinary healers' who treated measles-sickened children in Texas with budesonide, an anti-inflammatory steroid, and clarithromycin, an antibiotic used on bacterial infections. Dr. Paul Offit, director of the Vaccine Education Center at the Children's Hospital in Philadelphia, told NPR that budesonide has no role in treating measles while clarithromycin is not the correct antibiotic for treating secondary bacterial infections from measles. Kennedy furthered his support for the vaccine in an interview with CBS News, saying, 'The federal government's position, my position, is that people should get the measles vaccine,' though he did not say the government should mandate the vaccine. Kennedy, a vaccine skeptic, has also supported the use of vitamin A under the supervision of a physician to treat people with measles, creating concerns among health experts who have cautioned about the vitamin's effectiveness. Sue Kressly, president of the American Academy of Pediatrics, told The Washington Post that solely relying on vitamin A instead of the MMR vaccine is 'dangerous and ineffective' and can put children at risk, noting too much vitamin A can 'cause serious health problems, including liver damage.'
'Due to the highly contagious nature of this disease, additional cases are likely to occur in the outbreak area and the surrounding communities,' according to The Texas Department of State Health Services.
The Texas measles outbreak began in late January with just two cases and has become the state's largest outbreak of the virus in 30 years. The Texas Department of State Health Services said in a report of student immunization status for the 2023-2024 school year that 5.64% of Texas kindergarten students were not vaccinated for measles, while 2.34% of seventh graders had not received the vaccine. Measles was fully eliminated from the U.S. in 2000, according to the CDC, meaning the virus was not spreading within the country and new cases only came from people who contracted measles abroad and returned to the U.S. In 2024, a total of 285 measles cases were reported across 33 states.
