Health officials in New Mexico confirmed the second U.S. measles-related death in the ongoing outbreak that continues to spread across the American Southwest. The deceased was an unvaccinated adult residing in Lea County, approximately 50 miles from Gaines County, Texas, the reported epicenter of the outbreak.
This development follows the first measles fatality in the U.S. since 2015, involving an unvaccinated six-year-old child in Texas, reported on February 27.
Although the New Mexico Department of Health did not disclose the deceased adult’s age or gender, officials reiterated the seriousness of measles complications. According to the department, one in every five infections leads to hospitalization, and approximately three in every 1,000 cases result in death.
Measles Cases Climb Across the U.S. and Canada
The spread of measles has intensified significantly:
- Texas reported 198 cases as of Friday, an increase of nearly 30 cases in just three days.
- New Mexico's caseload tripled, reaching 30 confirmed cases during the same timeframe.
- Additional cases have been documented in Alaska, California, Florida, Georgia, Kentucky, New Jersey, New York, Pennsylvania, Rhode Island, and Washington, according to the Centers for Disease Control and Prevention (CDC).
As of March 2025, the CDC confirmed more than 220 cases nationwide... a concerning figure given that the total number of U.S. measles infections for all of 2024 was 285.
The CDC attributes the current outbreak to an initial cluster in a rural Mennonite community in Texas, an area known for low vaccination rates.
Measles in Canada: Infections Outpace Previous Year
The Public Health Agency of Canada (PHAC) also reported a spike in measles infections. As of Thursday:
- 227 confirmed cases have been documented in 2025, already exceeding Canada’s total count for 2024.
- Cases have appeared in Ontario, Quebec, and British Columbia.
- Chief Public Health Officer Dr. Theresa Tam stated the majority of infections are linked to travelers returning from abroad, introducing the virus into local populations with insufficient vaccination coverage.
Vaccination Remains the Primary Defense
Medical experts emphasize that the MMR (Measles, Mumps, Rubella) vaccine remains the most effective safeguard against the disease. The CDC and other health bodies reiterate the following facts:
- The MMR vaccine is 97% effective after two doses.
- Vaccination significantly reduces the risk of complications such as pneumonia, encephalitis (brain swelling), and death.
- The vaccine also contributes to community (herd) immunity, protecting vulnerable individuals unable to receive vaccinations for medical reasons.
Public Health Officials Urge Action Amidst Rising Concerns
The recent deaths have reignited discussions around vaccination skepticism and the dangers posed by declining immunization rates. In an opinion editorial published on Fox News, U.S. Health and Human Services Secretary Robert F. Kennedy Jr. who has historically expressed vaccine skepticism.. acknowledged the public health threat posed by the outbreak.
“Vaccines not only protect individual children from measles, but also contribute to community immunity, protecting those who are unable to be vaccinated due to medical reasons,” Kennedy wrote.
Background: Measles Declared Eliminated in 2000, But Outbreaks Persist
Although measles was declared eliminated in the U.S. in 2000, meaning the disease was no longer continuously transmitted, sporadic outbreaks have occurred.. usually sparked by international travel and unvaccinated clusters.
The last reported measles death in the U.S. prior to 2025 occurred in 2015, and before that, in 2003. By contrast, the current outbreak has claimed two lives within a matter of weeks, raising concerns among epidemiologists and public health agencies.
An outbreak is officially defined by the CDC as three or more linked cases in a given area... a threshold now significantly surpassed in several states.
Conclusion: Urgency for Immunization and Surveillance
Health agencies across North America are intensifying efforts to contain the spread, urging residents to ensure vaccination status is up-to-date, particularly for children and international travelers.
Experts warn that without rapid immunization outreach and improved public awareness, the current outbreak may continue to expand... reversing decades of progress in disease prevention.
