Measles outbreaks have been reported throughout the country, with a notable number of cases emerging in regions where vaccination rates are currently low. In the previous year, 285 cases were recorded by the US Centers for Disease Control and Prevention—the highest count since 2019. Recent weeks in 2025 have already seen cases in metro Atlanta, New Mexico, West Texas, as well as additional instances in Alaska, Rhode Island, and New York City.
Measles is a highly contagious respiratory virus that spreads via airborne particles, and it can lead to symptoms such as a rash, fever, red eyes, and cough. In more severe cases, individuals may develop complications like pneumonia, blindness, encephalitis, or other critical health issues. Historically, before the advent of the vaccine in 1963, measles caused millions of deaths worldwide, a stark contrast to the relatively lower fatality count in recent years primarily due to vaccination efforts.
Vaccination remains the most effective protection against measles, with the MMR vaccine boasting a 93% efficacy after one dose and 97% with two doses. Health officials recommend that children receive their first dose between 12 and 15 months and a second dose around the age of four, creating a protective barrier not only for the individual child but also for the broader community.
For those unsure of their vaccination history, titer tests can assess the level of antibodies against measles. These tests might be particularly useful for people who lack their vaccination records or for immunocompromised individuals, although many doctors note that if someone has received both doses of the MMR vaccine, additional testing may not be necessary. Experts stress the importance of maintaining high vaccination rates, warning that declining coverage can pave the way for further outbreaks and vaccine-preventable illnesses.
