In late September 2025, nearly 100 passengers and crew aboard Serenade of the Seas were sickened by norovirus, according to the CDC. While the outbreak has since passed, it’s a reminder of how quickly gastrointestinal illnesses can spread at sea and what you can do to keep your family safe.
What is Norovirus?
Norovirus is a highly contagious virus that causes stomach and intestinal inflammation (gastroenteritis). Symptoms usually appear 12–48 hours after exposure and include:
- Diarrhea
- Vomiting
- Nausea
- Stomach pain
- Sometimes fever and body aches
It only takes a very small number of viral particles to cause infection, and people can still spread norovirus for a couple of days after symptoms improve.
Why Cruises See Outbreaks
Cruise ships aren’t riskier than hotels or schools but the close environment means illness can spread faster. Norovirus is tough because:
- It spreads through contaminated food, water, or surfaces.
- It survives for days on objects like door handles, railings, and elevator buttons.
- It isn’t killed by alcohol-based hand sanitizer alone.
- Outbreaks are tracked and investigated by the CDC’s Vessel Sanitation Program.
What Cruise Lines Do During an Outbreak
When illness is reported, Royal Caribbean and other lines take immediate action:
- Step up cleaning and disinfecting high-touch areas.
- Collect stool samples to confirm norovirus.
- Isolate ill passengers and crew.
- Transition buffets to crew service instead of self-service.
- Communicate with the CDC and follow public health protocols.
What You Can Do to Protect Your Family
Here are the best prevention strategies, straight from the CDC and seasoned cruisers:
- Wash your hands with soap and water for 20 seconds, especially before eating or after using the restroom. Hand sanitizer alone isn’t effective.
- Disinfect your cabin and dining area: wipe down handles, light switches, TV remotes, and tables.
- Avoid touching your face after using shared railings or elevator buttons.
- Stick to cooked foods and crew-served buffets. Skip raw oysters and other risky foods.
- Use your own water bottles and utensils if your child is prone to sharing.
- Rest and hydrate: a strong immune system helps fight off illness.
- Isolate quickly if sick and contact onboard medical staff. Early action prevents further spread.
- Monitor symptoms for 48 hours after disembarkation. Norovirus can appear even after you’re home.
FAQs
Is norovirus only on cruise ships?
No. Norovirus is the leading cause of gastroenteritis worldwide. Cruise ships are just required to report outbreaks to the CDC, so they make headlines.
Will my whole family get sick if one person does?
Not always. Good hygiene and quick isolation reduce the chance of spreading it within your cabin.
Is it safe to eat at the buffet?
Yes, but practice caution. During outbreaks, crew often serve food instead of self-service. Stick to hot, cooked items.
Does travel insurance cover trip interruptions from norovirus?
Most policies cover medical treatment onboard and trip interruption if illness prevents you from traveling. Always read your plan’s fine print.
Bottom Line
Cruising with kids should be fun, not stressful. By practicing a few extra hygiene steps and staying alert, you can greatly reduce your family’s risk of picking up norovirus at sea.
