Health experts have criticized the Trump administration for not taking decisive actions to curb the spread of measles, as the number of cases in the United States has now exceeded 1,000.

According to these experts, the administration’s approach to managing the highly contagious virus has been notably lax, both in terms of public messaging and the allocation of funds.

Alonzo Plough, a seasoned public health official and chief science officer at the Robert Wood Johnson Foundation, pointed out that a senior CDC official described the alarming rise in measles cases and related deaths in some states as merely the “cost of doing business.”

Plough was referring to remarks made by Dr. Ralph Abraham, who held the position of CDC principal deputy director starting in December 2025 and resigned by late February. For Plough, such comments from CDC leadership indicate a lack of seriousness in addressing the issue.

However, Andrew G. Nixon, a spokesperson for the Department of Health and Human Services, refuted claims that the CDC has downplayed the importance of tackling measles.

“The CDC remains committed to measles prevention and treatment education, focusing on targeted public health interventions to safeguard communities and deliver clear, accurate information to the American public,” Nixon stated.

Florida’s former surgeon general and a current professor at Brown University’s school of public health, Dr Scott Rivkees, said that current messaging on public health is causing “tremendous confusion to the public”, with “individuals in senior positions who are advocating for things that the medical community will take issue with”, like “alternatives” to the measles vaccine, which is known to be safe and effective.

But while Rivkees says messaging has been confusing on the national level, he added that the local health department in Spartanburg county, South Carolina, which is experiencing the most severe US measles outbreak, is doing everything it should, including ramping up vaccination clinics and posting billboards urging people to vaccinate.

An HHS spokesperson said: “CDC has provided support to some jurisdictions experiencing large outbreaks based on requests for additional support from them.” South Carolina specifically requested “non-CDC reinforcements” in its battle against measles, Reuters reported.

Previously, the CDC would have issued regular reports, alerts and social media posts to help people protect themselves during outbreaks like these. But CDC communications about measles outbreaks over the last year have been minimal.

For several months after the first 2025 outbreak, the CDC rarely posted about measles on its X account. One of the few measles-related posts went on the defensive, telling followers that “framing measles as an American policy failure is inaccurate and misleading” while linking to a letter to the Wall Street Journal by former CDC principal deputy director Abraham.

In it, Abraham wrote that “we can’t rely exclusively on vaccination [to prevent measles]”. Ninety-four percent of measles cases have occurred among individuals who are unvaccinated or whose vaccination status is unknown. Earlier this month, the CDC’s X account posted a video of CDC acting director Jay Bhattacharya, wherein he encourages people to get vaccinated, though the text of the post does not mention vaccines.

Some experts said that the Trump administration’s significant cuts to CDC funding streams, which help public health officials track and contain health problems at the local, state and national levels, last year have greatly contributed to the lack of public communication from the government about measles.

“Disease surveillance is a bit of a pyramid,” said Jennifer Nuzzo, director of the pandemic center at Brown University.

At the bottom of the pyramid, Nuzzo said, are hospitals that track when children arrive with possible measles symptoms and when they test positive. They share this information with local health departments, and the data sharing goes all the way up to the national CDC level. But cuts have slowed that entire process.

“What we’ve seen in the past year is just an erosion of all capacities due to broader funding cuts, not necessarily specifically targeting measles,” Nuzzo continued.

Plough echoed Nuzzo on the impact of the cuts to core CDC staff. Those cuts have coincided with delays in reports on morbidity and mortality that the CDC used to release on a routine basis, indicating that the reporting on health data from the CDC “has been severely compromised” Plough said.

The experts agree that due to the cuts and the delays in reporting, Americans likely do not know the full gravity of the current measles outbreaks. Nuzzo says that because the US has seen three measles fatalities so far, it suggests a much higher number of total cases than the approximately 1,100 that have been tracked so far.

One cost-effective way to fill in those gaps would be to ramp up wastewater surveillance, says Nuzzo. Wastewater data can help estimate cases before they’re detected clinically, and can even be used as a substitute for clinical detection in areas that are lagging behind. Funding streams dedicated specifically to Covid-19 ramped up the country’s wastewater surveillance system, but that supplemental funding expired last year. Additionally, the Trump administration has proposed cuts for this type of surveillance from $125m to $25m annually. Nuzzo said that if the administration took measles containment seriously, it would expand that funding instead.

Rivkees believes that US public health systems will be restored to their past efficacy, as Congress recently restored much of CDC’s funding. Plough is less certain.

“Yes, some money has been restored,” he said, but “money being restored and money being out into the right areas are two different things”.

Since Congress replenished the CDC’s funding package, the Trump administration has looked for other ways to pull dollars from state and local health departments.

“I’m usually a big glass-half-full guy, but not particularly on this one,” Plough said.

If people more widely vaccinated their children, Nuzzo said, conversations about surveillance funding wouldn’t be needed: “No amount of surveillance is going to end this, unless people get vaccinated, because the only thing that ends this is immunity.”
