What You Need to Know About the Measles Outbreak in Texas

As of March 3, 2025, the Texas Department of State Health Services (DSHS) has reported 146 confirmed cases of measles since late January. This marks one of the largest outbreaks in the U.S. since measles was declared eradicated in 2000. Unfortunately, the recent decline in childhood vaccination rates has contributed to this resurgence.

What is Measles?

Measles is a highly contagious viral infection that typically causes a full-body rash and flu-like symptoms. In some cases, it can be life-threatening, with a mortality rate of approximately 3 in 1,000. While serious, measles primarily affects individuals who are unvaccinated or have weakened immune systems.

Who is at Risk?

While most healthy adults have been vaccinated, certain groups remain vulnerable:

• Unvaccinated Children: Infants and young children who have not yet received the Measles-Mumps-Rubella (MMR) vaccine are at the highest risk.

• Individuals with Weakened Immune Systems: People undergoing cancer treatment, those with autoimmune diseases, and individuals taking immunosuppressant medications may be more susceptible.

• Travelers: Those visiting areas with active outbreaks are at a higher risk of exposure.

The MMR vaccine is highly effective at preventing measles. One dose is 93% effective, while two doses offer 97% protection and provide lifelong immunity. The first dose is recommended between 12-15 months, with a second dose administered between 4-6 years.

What You Can Do to Protect Yourself

If you’re unsure whether you’ve been vaccinated, we can perform a simple blood test (titer) to check your immunity. If your immunity is low, we can provide an MMR booster to ensure you’re fully protected. Staying informed and up to date on vaccinations is key to preventing measles and other contagious diseases.
