The US Has 44 Days to Prove It Still Beat Measles

On April 13, a committee in Washington will vote on whether the United States is still a country that eliminated measles.

The answer, almost certainly, is no.

The numbers

The CDC confirmed 1,136 measles cases in 2026 as of February 26. That's under two months. All of 2025 had 2,281. All of 2024 had 285.

The US is on pace to shatter every record since declaring measles eliminated in 2000.

South Carolina alone: 632 cases. Utah: 117. Florida: 64. Twenty-eight states have reported infections. Three people died from measles in 2025 — two of them children in Texas.

The week ending February 26 saw cases jump 7.9%. The curve isn't flattening. It's steepening.

What "elimination" actually means

Elimination doesn't mean zero cases. It means no continuous chain of the same virus strain spreading domestically for 12 months. Imports are expected. Sustained local transmission breaks the designation.

PAHO certified the US measles-free in 2000 — the result of decades pushing MMR coverage above 95%, where herd immunity stops the virus cold.

Now PAHO's invited the US to an April 13 review. The question: are the 2025 and 2026 outbreaks linked by the same strain spreading domestically? If yes, certification's gone.

The BMJ reported this week that experts expect yes.

The slow erosion

This didn't happen overnight. It took five years, one percentage point at a time.

MMR vaccination among US kindergartners dropped from 95.2% (2019-2020) to 92.5% (2024-2025). Below the 95% herd immunity line. That left roughly 286,000 kindergartners unprotected.

The national number hides worse pockets. Briscoe County, Texas — ground zero of the 2025 outbreak — had 80% coverage. Childress County: 70.5%. Three in ten kids entering school with no measles protection.

Thirty-nine states now fall below 95%. In 2019-2020, that number was 28.

The confidence collapse

Adult support for the MMR vaccine dropped from 90% to 82% in a few months during 2025, per CIDRAP. That's a massive shift for a vaccine with decades of safety data.

Robert F. Kennedy Jr., now leading HHS, overhauled the childhood vaccine schedule shortly after taking office. His Advisory Committee on Immunization Practices includes members with vaccine-skeptic histories. HHS's outbreak response emphasized vitamin A and cod liver oil — not vaccination.

Politico reported this week that the administration is quietly pivoting away from vaccine messaging as midterm calculations shift. The damage is already baked in.

When the person running public health casts doubt on vaccines, some parents listen. The numbers show exactly how many.

What losing elimination means

Losing the status doesn't trigger policy changes. No borders close. No new mandates.

But it sends a signal. The US joins countries that beat measles and then lost it — the UK (2019), Albania, Czech Republic, Greece. Canada's also under review.

For a country that spent billions building the world's best public health system, it's a symbolic gutting. We had this. We let it go.

Practically, it means the virus has re-established itself. Outbreaks won't be imports that burn out. They'll be domestic chains that keep spreading. More hospitalizations. More deaths. More school closures.

Measles is one of the most contagious diseases known. One infected person spreads it to 90% of unvaccinated people nearby. It lingers in the air two hours after they leave. There's no treatment — only prevention, and prevention means a needle before exposure, not after.

The math ahead

The US adds 3.6 million kindergartners every year. At 92.5% coverage, that's 270,000 unvaccinated kids entering the population annually. The gap compounds.

Rebuilding to 95% means reaching families who actively opted out — not those who forgot, but those who made a choice based on information they trusted.

That trust took decades to build. Eroding it took months.

Forty-four days

PAHO meets April 13. By then, the US will likely have over 2,000 cases — surpassing all of 2025 before spring.

The committee won't make a political decision. They'll read the epi data and ask one question: is measles spreading continuously within the United States?

The data already answers that. The vote's a formality.

Twenty-five years ago, the US proved measles could be beaten with science, funding, and public trust. April 13 will show what happens when one of those three breaks.
