Why Measles Is Especially Dangerous
Measles is among the most contagious viruses known, spreading through the air and remaining infectious for hours after an infected person leaves an area. Complications can include pneumonia, brain swelling, and death, particularly in young children and immunocompromised individuals.
Medical experts emphasize that the measles, mumps, and rubella (MMR) vaccine remains highly effective. One dose provides strong protection, while the recommended two-dose series offers near-complete immunity.
International health agencies are expected to reassess measles elimination status for the U.S. later this year. Canada lost its status recently after sustained outbreaks, and experts warn the United States could face the same outcome if transmission continues.
Public health leaders stress that losing elimination status would signal deeper vulnerabilities in disease prevention systems and could open the door to the return of other previously controlled illnesses.
What the Public Can Do
Health officials urge parents and caregivers to verify vaccination records, especially for children attending school or daycare. Individuals experiencing symptoms such as fever, cough, runny nose, or rash are advised to seek medical care and avoid public spaces to prevent further spread.
Experts agree that vaccination remains the most effective defense against measles and a critical tool in preventing future outbreaks.
