Nearly 120 people aboard a cruise ship that set sail from Florida this month have fallen ill with norovirus, according to the Centers for Disease Control and Prevention (CDC).

The CDC’s Vessel Sanitation Program has identified Holland America Line cruise ship ms Rotterdam as the latest vessel to experience an outbreak this year. The ship is currently on a 12-night Panama Canal cruise that departed from Port Everglades on February 2 and is set to return on February 14.

According to the CDC, 107 of 2,614 passengers (4.1%) and 12 of 969 crew members (1.2%) have reported symptoms of illness since the first case was identified on February 7. These numbers represent cumulative cases throughout the cruise and do not indicate that all individuals were sick at the same time. Reported symptoms include diarrhea and vomiting.

In response, the ship’s crew has ramped up cleaning and disinfection procedures in accordance with the cruise line’s outbreak prevention plan. Specimens from both passengers and crew have been collected for testing, and the CDC is remotely monitoring the situation while consulting with the cruise line.

Ms Rotterdam is the seventh cruise ship with reported outbreak by the CDC in 2025 and the fourth confirmed to be caused by norovirus. It follows a recent outbreak of an unidentified illness with similar symptoms on Royal Caribbean’s Radiance of the Seas, which sailed from Tampa. That outbreak affected 160 of 2,164 passengers (7.4%) and eight of 910 crew members (0.9%) before the ship returned on February 8. The CDC has yet to determine the cause of that incident.
