Norovirus Infects More Than 100 Cruise Passengers On Board, Details Inside

<strong><span rel="noindex">Norovirus Outbreak</span>: </strong>In a globe-hopping cruise ship, more than 100 guests and crew reported being sick with <span>norovirus</span> outbreak. As per the Centers for Disease Control and Prevention (CDC), the 21st outbreak of gastrointestinal disease on a cruise ship monitored by the agency this year. 

AIDA Cruises alerted the CDC to the outbreak aboard the AIDAdiva on November 30, confirmed the agency. So far, the outbreak has impacted 95 passengers out of the 2,007 onboard, and 6 out of 640 staff members, noted CDC. 

The passengers also suffered symptoms like diarrhea and vomiting on voyage, which had begun on November 10 and is slated to last through December 16. The cruise line responded by stepping up cleaning and disinfection efforts, separating sick passengers and crew from others, working closely with the CDC’s Vessel Sanitation Program, and collecting stool samples for testing, the agency said.

<h2>What Are The Cruise Officials Doing About The Ship Outbreak?</h2>

“Seasonal illness peaks between November and April, and the AIDAdiva report mirrors what we’re seeing on land,” AIDA told People. “We’ve increased hygiene measures onboard, and cases are already declining.”

The Independent reports that AIDAdiva is currently midway through its 133-day voyage from Hamburg, Germany, with planned stops across North America. According to CruiseMapper, the ship is now in Costa Rica.

This outbreak is the 21st recorded this year on a CDC-regulated cruise ship, most of them caused by norovirus. That’s higher than the recent yearly totals: 18 outbreaks in 2024 and 14 in 2023. While cruises are often linked with norovirus, only a small share of overall cases actually occur at sea. In most years, ship outbreaks simply mirror seasonal spikes happening on land.

Officials say it’s too soon to say why numbers are up.

“Although cruise ship outbreaks have been higher than in pre-pandemic years, we don’t yet know if this is a lasting trend,” the CDC told USA TODAY in April. They added that a newly dominant norovirus strain is driving many land-based outbreaks this season, and ships usually follow the same pattern.

Norovirus is the leading cause of vomiting, diarrhea, and foodborne illness in the U.S. It triggers acute gastroenteritis, an inflammation of the stomach or intestines. Most people recover within one to three days, but they can remain contagious even after symptoms improve.

The virus spreads easily through contaminated food, surfaces, or close contact. Regular handwashing, proper cooking and cleaning of produce and shellfish, and routine disinfection of surfaces are key steps to prevent infection.

Often called the “stomach flu” or “stomach bug,” norovirus is not related to influenza. It causes acute gastroenteritis, an inflammation of the stomach and intestines. Most people recover within 1 to 3 days, but the virus can still be contagious for several days afterward. In 2025 alone, the CDC has recorded 19 gastrointestinal outbreaks on cruise ships, 14 of which were caused by norovirus. The CDC notes that such illnesses spread quickly in enclosed environments like cruise ships.

<h2>Unique Symptoms Observed on This Cruise</h2>

Norovirus symptoms usually appear 12 to 48 hours after exposure. While diarrhea, vomiting, nausea, and stomach cramps remain common, this outbreak has shown some unusual signs:

<ul><li>Dehydration</li><li>Reduced urination</li><li>Dry mouth and throat</li><li>Feeling dizzy when standing</li><li>Crying with few or no tears</li><li>Unusual sleepiness or irritability</li></ul>
