Measles outbreak looms in US as cases surge, health officials warn

The United States is on track to see the highest number of measles cases in 35 years, with the current total nearing last year's figures despite it being only halfway through 2026. This surge is a serious public health warning, according to epidemiologist Dr. Syra Madad.

This is a serious public health warning. The United States is already very close to last year's total number of cases, even though only about half the year has passed.

The highly contagious virus spreads through respiratory droplets and can linger in the air for up to two hours. Symptoms include high fever, cough, runny nose, and red, watery eyes, followed by a characteristic rash. Infected individuals are contagious for about four days before and after the rash appears.

Measles can cause pneumonia, encephalitis, hospitalization, and death, especially in young children and people with compromised health.

Dr. Madad highlighted that measles can lead to severe complications such as pneumonia, encephalitis, hospitalization, and even death, especially in young children and individuals with underlying health conditions. Data from the U.S. Centers for Disease Control and Prevention (CDC) indicates that 93% of this year's cases involve unvaccinated individuals or those with an unknown vaccination status. Children aged five to 19 constitute over half of those infected.

Measles will continue to find susceptible communities next year, and in the years after that. This means more epidemics, more quarantines, more disruptions to classes in schools and kindergartens, greater pressure on already overburdened health services, and continued risk of severe forms of the disease and death from a disease we know how to prevent.

If vaccination gaps persist, the future could be even more concerning, Madad warned. Measles will continue to find susceptible communities, leading to more outbreaks, quarantines, and disruptions to schools. This places a significant burden on healthcare systems and maintains the risk of severe illness and death from a preventable disease. The U.S. has successfully eradicated measles before and can regain control by increasing MMR vaccination rates, strengthening surveillance, and responding swiftly to new cases.

The United States has already managed to eradicate measles once and can again bring the disease under control by increasing vaccination with the MMR vaccine, strengthening the surveillance system, and responding quickly to every new case.
