BREAKING: US Measles Cases Just Hit a "Grim Milestone". Here's What You Need to Know
US measles cases have reached 2,295 in 2026, surpassing the total for all of 2025 and marking the highest numbers seen since 1991. Public health experts describe the outbreak as a preventable crisis driven by declining vaccination rates.
Why it matters
The resurgence of a highly contagious, vaccine-preventable disease poses a significant threat to public health and highlights the consequences of vaccine hesitancy.
Add ScienceAlert on Google Measles cases in the United States have just passed a "grim milestone", reaching numbers that haven't been seen in 35 years.
In 2025, the Centers for Disease Control and Prevention reported a total of 2,289 measles cases.
Today, 21 July 2026, that number was officially breached, reaching 2,295 at the time of writing.
The last time US measles cases exceeded this 2026 number was in 1991, when 9,643 cases were reported, following 27,808 cases in 1990.
Annual cases dropped in the following years, to just 312 in 1993, after a second vaccine dose was recommended and school vaccination programs began.
Since then, measles case numbers have remained low.
Public health experts are deeply concerned. Last year, three people died from the disease. No deaths have yet been reported in 2026, but with each new case, the odds are getting worse.
