US Measles Cases Hit 35-Year High
Over 2,300 infections confirmed in 2026 as vaccination rates plummet to 92.7%
The United States has recorded its highest number of measles cases in 35 years, with more than 2,300 infections confirmed in 2026. This surpasses the total number of cases in 2025, which was 2,286, according to the US Measles Tracker run by the Johns Hopkins Bloomberg School of Public Health.
The number of measles cases in the US has been rising, with 2,321 reported cases by mid-July 2026. Declining vaccination rates are contributing to the surge in infections, with only 92.7% of kindergartners in the US vaccinated against measles during the 2023-2024 school year, down from 93% in the 2021-2022 school year.
The US has held measles elimination status since 2000, but is at risk of losing it due to ongoing outbreaks. Dr. Jay Bhattacharya, director of the National Institutes of Health, has expressed his trust in the science behind vaccines, saying 'I trust the science' as measles cases have risen to their highest levels in 35 years.
## Why it matters The rise in measles cases has significant implications for public health in the US. Measles is a highly contagious virus that can cause lasting harm or death, and the fading memories of the once-common disease have left too many people unaware of its dangers. Experts warn that the growing pockets of susceptible people due to declining vaccination rates have created an environment where the virus can spread easily. The US is now at risk of losing its measles-elimination status, which it has held since 2000.
## What happens next The surge in measles cases is expected to continue, with the virus spreading from one susceptible community to another within the US. This has led to concerns that the US will not be able to stop measles virus transmission or outbreaks as it has in the past. The significance of reaching this milestone is that the US has not been able to contain the spread of the virus, and it is now a major public health concern.
The situation highlights the importance of vaccination in preventing the spread of measles. With the virus being highly contagious and able to spread before symptoms appear, it is crucial that people are vaccinated to prevent outbreaks. The US needs to take measures to address the declining vaccination rates and prevent further outbreaks, or risk losing its measles-elimination status.
