Norovirus outbreak cruise ship: The Centers for Disease Control and Prevention (CDC) confirmed that almost 100 passengers became ill during a 13-day Royal Caribbean cruise, according to NBC Miami on Thursday, October 2, 2025. The ship, Serenade of the Seas, departed from San Diego on September 19, 2025 and docked at the Port of Miami after the outbreak was reported to the CDC’s Vessel Sanitation Program. Passengers who fell sick began experiencing several notable symptoms, which we break down below.

The CDC reported that 94 of 1,874 passengers and 4 of 883 crew members fell ill during the voyage, with the most common symptoms being diarrhea and vomiting. Passenger Bob Pettit, 87, shared his experience: “It really hits you hard, violently. I’ve been on twenty-five cruises, and this is the first time I’ve been this sick in my life.”

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.

Norovirus outbreak cruise ship: Unique Symptoms Observed on This Cruise

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>

According to the CDC, anyone can contract norovirus, but some groups are more vulnerable. Young children, older adults, and people with weakened immune systems may experience more severe symptoms. Genetics may also play a role in susceptibility. Eating raw shellfish, such as oysters, can also increase the risk, as they may contain harmful viruses or bacteria.

Symptoms typically last 1 to 3 days and generally improve with rest and hydration. However, people remain contagious for at least 48 hours after symptoms stop, and children with diaper rash may shed the virus for up to 7 days. Seek medical care if severe dehydration develops or if symptoms persist beyond a few days.

According to CDC, Norovirus spreads very easily, starting from the moment symptoms appear and continuing for at least three days after recovery, and sometimes up to two weeks. Even after symptoms disappear, the virus can still be passed to others for several weeks, and in some cases, people may carry and shed the virus for months.
