First two positive cases of the measles confirmed in Tarrant County

Two individuals tested positive for measles in Tarrant County, according to Tarrant County Public Health (TCPH).

The two people to test positive are an adult and a child, who are household members and are unvaccinated, according to a media release from TCPH.

It's unclear where the student may have contracted the virus.

Officials said the individuals visited the Methodist Mansfield ER on Broad Street on April 29 from 8 p.m. to 3 a.m. while contagious.

Anyone who was at the location should monitor themselves for symptoms until May 20, according to officials.

Cook Children's warned patients of the reported infections Saturday.

The health care system posted on social media that no cases have been reported at Cook Children’s Medical Centers in Fort Worth or Prosper.

It urged those who suspect their child may have measles to call their doctor or Urgent Care Center before arriving so arrangements can be made to minimize potential exposure.

What is measles?

Measles is a respiratory virus that can survive in the air for up to two hours. According to the U.S. Centers for Disease Control and Prevention, up to nine out of 10 people who are susceptible will get the virus if exposed.

Most kids will recover from measles if they get it, but infection can lead to dangerous complications like pneumonia, blindness, brain swelling, and death.

Is the vaccine safe?

Yes, the measles, mumps and rubella (MMR) vaccine is safe and highly effective in preventing measles infection and severe cases of the disease.

The first shot is recommended for children between 12 and 15 months old, and the second for children between 4 and 6 years old. The vaccine series is required for kids before kindergarten in public schools nationwide.

Before the vaccine was introduced in 1963, the U.S. saw some 3 million to 4 million cases per year. Now, there are usually fewer than 200 in a normal year.

There is no link between the vaccine and autism, despite a now-discredited study and health disinformation.

Why do vaccination rates matter?

In communities with high vaccination rates — above 95% — diseases like measles have a harder time spreading through communities. This is called “herd immunity.”

But childhood vaccination rates have declined nationwide since the pandemic and more parents are claiming religious or personal conscience waivers to exempt their kids from required shots.

The U.S. saw a rise in measles cases in 2024, including an outbreak in Chicago that sickened more than 60. Five years earlier, measles cases were the worst in almost three decades in 2019.

Gaines County has one of the highest rates in Texas of school-aged children who opt out of at least one required vaccine, with nearly 14% of K-12 children in the 2023-24 school year. Health officials said that number is likely higher because it doesn’t include many children who are homeschooled and whose data would not be reported.

What are public health officials doing to stop the spread?

Health workers are hosting regular vaccination clinics and screening efforts in Texas, as well as working with schools to educate people about the importance of vaccination and offering shots.
