Measles cases in the United States have soared to their highest level in 33 years, with around 1,300 incidents recorded over the last seven months, as reported by the Centers for Disease Control and Prevention.
The total number of confirmed measles cases has reached at least 1,288, marking the highest figure since 1992. More than 90% of those infected are either unvaccinated or their vaccination status is unknown, according to the CDC’s latest update.
This significant surge in measles cases, which was once thought to be eliminated due to a nationwide vaccination campaign, largely stems from an outbreak in West Texas, where most of the cases have been reported.
The ongoing outbreak in 2025 has resulted in hundreds of hospitalizations due to the disease, along with the first measles-related death in a decade—an unvaccinated child who passed away in February.
Currently, measles cases have been reported in 38 states, including New York and New Jersey, with 88% of the infections tied to this outbreak.
This situation echoes the anxiety experienced during the 2019 outbreak, which saw a sharp rise in cases and even a spike in lawsuits related to vaccination policies in the U.S.
Two and a half decades ago, the U.S. was celebrating its progress in controlling diseases like measles. However, declining vaccination rates have created vulnerable communities, allowing the virus to resurface.
The outbreak began in areas of Texas where vaccination rates are particularly low, with over 750 cases already noted in 2025.
In a concerning development, health officials in Kentucky announced their own outbreak this week after identifying 11 new cases, all linked to individuals who were not fully vaccinated.
The CDC has emphasized that to effectively prevent measles outbreaks, at least 95% of the population needs to be vaccinated.
While children are typically required to receive both doses of the measles vaccine to enroll in public schools, numerous states permit parents to opt out through non-medical exemptions—a trend that has grown since 2010.
Last year, only 92.7% of kindergarteners nationwide were fully vaccinated, and some areas are reporting even lower rates, which raises alarm for public health officials.
The current outbreak has prompted renewed scrutiny of Robert F. Kennedy Jr.’s role as the Secretary of Health and Human Services, as he has faced criticism for promoting controversial views on vaccines and unproven treatments for measles.
Healthcare providers are also warning about the potential rise in subacute sclerosing pan encephalitis (SSPE), a rare, progressive neurological condition associated with the measles virus.
According to the National Institutes of Health (NIH), SSPE usually develops 7 to 10 years after a measles infection, and treatment options remain unknown. Almost all cases of SSPE are fatal, according to health authorities.
