FORT LAUDERDALE, Fla. — All full-time employees in the Centers for Disease Control and Prevention’s Vessel Sanitation Program were laid off this week, even as a cruise ship arrived in Miami with another norovirus outbreak among passengers and crew.

The CDC employees whose jobs were cut were responsible for monitoring, tracking and assisting with gastrointestinal outbreaks on cruise ships. The epidemiologist tasked with leading the federal agency’s outbreak response on cruise ships also was included in the layoffs, CDC officials told CBS News.

The cuts are problematic for Florida, where passengers disembark from cruise ships with gastrointestinal viruses and often travel through airports. The CDC documented a dozen outbreaks on ships in just the first four months of 2025, mostly from norovirus. Ten of those ships departed from, or docked in, Florida or both. The outbreaks involved as many as hundreds of passengers and crew members falling ill with symptoms like vomiting, diarrhea, and abdominal cramps.

On Wednesday, Seaborn Cruise Lines Encore arrived in Miami after a 3½-week voyage. Thirty-five of the roughly 800 people on board had become ill with norovirus. The cruise line reported that it consulted with Vessel Sanitation Program officials about sanitation cleaning procedures. “VSP remotely monitored the situation, including review of the ship’s outbreak response and sanitation procedures,” the CDC website says.

Employees in the Vessel Sanitation Program were cut as part of Health and Human Services Secretary Robert F. Kennedy Jr.’s major layoffs in public health.

A CDC spokesperson told the South Florida Sun Sentinel, “Critical programs in the CDC will continue under Secretary Kennedy’s vision to streamline HHS to better serve Americans.”

The spokesperson also said that unannounced sanitation inspections, monitoring and assisting with gastrointestinal outbreaks and tracking and reporting illnesses on cruise ships has not stopped and the work will now be done by U.S. Public Health Service officers.

CBS reported that only one epidemiologist remains on the Vessel Sanitation Program’s team to investigate outbreaks and that individual is still in the early stages of training.

Florida and many areas of the U.S. have been battling a record surge of norovirus in recent months, driven mainly by a new strain of the gastrointestinal virus.

Wastewater samples throughout Florida — home to seven major cruise ports — show high levels of norovirus as of April 7. Verily’s wastewater program provides surveillance of norovirus and other pathogens at 11 sites in Florida, including two in Miami-Dade County and one in Jupiter. Wastewater testing at all three tracked high levels of norovirus.

“In all three South Florida wastewater treatment facilities in which Verily monitors pathogens, we’ve seen persistently high levels of Norovirus GII since November/December 2024,” said Amy Lockwood, Verily’s Public Health Partnerships Lead. “While an uptick during this season is expected, the levels we are seeing are significantly higher than the same time period in 2024 and 2023.”

Also, high levels of norovirus were reported in three of the four Central Florida (Orange County) wastewater sites. The fourth has a medium level. The site closest to Port Canaveral, which hosts multiple Disney cruises, has a high level.

“These early warning signs help officials get ahead of outbreaks, and right now, the data suggests an increased transmission risk as travelers come and go,” Lockwood said.
