The Southwest United States is currently grappling with a severe measles outbreak, with Texas and New Mexico experiencing the highest number of reported cases. As of March 4, 2025, health officials have confirmed at least 168 cases and one reported fatality. Experts attribute the outbreak to declining vaccination rates, increased travel, and delayed public health interventions.
Measles, a highly contagious viral infection, can cause severe complications, including pneumonia, brain swelling, and death. The Centers for Disease Control and Prevention (CDC) and local health departments are working tirelessly to contain the outbreak and prevent further spread.
What is Measles?
Measles is an airborne disease caused by the Measles morbillivirus. It spreads when an infected person coughs, sneezes, or comes into direct contact with others. The virus can remain in the air for up to two hours, making it extremely contagious.
Symptoms of Measles
The initial symptoms of measles typically appear 7–14 days after exposure and include:
- High fever
- Cough and runny nose
- Red, watery eyes
- White spots inside the mouth (Koplik spots)
- A red rash that spreads from the face to the rest of the body
Severe complications can occur, especially in young children, pregnant women, and immunocompromised individuals. According to the World Health Organization (WHO), measles-related complications lead to over 100,000 deaths globally each year.
Causes of the Southwest Measles Outbreak
Health experts have identified three primary causes for the 2025 measles outbreak in Texas and New Mexico:
1. Declining Vaccination Rates
In recent years, vaccine hesitancy has increased across the United States. Misinformation about the Measles, Mumps, and Rubella (MMR) vaccine has led to lower immunization rates, especially in rural and underserved communities.
According to the CDC, measles vaccination rates have dropped below 90% in some areas, making outbreaks more likely. The American Academy of Pediatrics warns that herd immunity requires at least 95% of the population to be vaccinated to prevent widespread transmission.

2. Increased Interstate Travel
Texas and New Mexico have seen a surge in domestic and international travel, increasing exposure to measles-infected individuals. Many unvaccinated travelers have unknowingly spread the virus to schools, childcare centers, and public places.
3. Delayed Public Health Response
The initial response to the outbreak was slow, allowing the virus to spread before containment measures were implemented. Some state health departments struggled with limited resources and delayed reporting.
Efforts to Contain the Outbreak
Health officials in Texas and New Mexico have taken several urgent steps to contain the outbreak:
1. Emergency Vaccination Clinics
The Texas Department of State Health Services and the New Mexico Department of Health have launched free measles vaccination clinics in affected communities.

2. School Immunization Requirements
Schools in high-risk areas are requiring proof of MMR vaccination for students and staff. Non-compliant students may be required to stay home until the outbreak subsides.
3. Public Awareness Campaigns
Officials are using social media, television, and community outreach to counter vaccine misinformation and encourage immunization.
How to Protect Yourself
The best way to protect yourself and your family from measles is to get vaccinated. The MMR vaccine is 97% effective at preventing measles and is safe for children and adults.
Who Should Get Vaccinated?
- Infants: First dose at 12–15 months, second dose at 4–6 years
- Unvaccinated adults: At least one dose of MMR vaccine
- Healthcare workers & travelers: Two doses for full protection
