# What I Tell Every Cruiser About Avoiding Norovirus (and the Other Bugs Most Don't Mention) *By James Hills, cruisewestcoast.com — Updated April 2026* Written by: [James Hills](https://cruisewestcoast.com/james-hills.html) Published: 30 April 2026 Last Updated: 30 April 2026 Evergreen BlogHits: 10055Reading time: 12:37 Most people I know who cruise regularly have had something on a cruise. Not always norovirus, but something - a stomach bug, a head cold, a few bad hours after a too-rich dinner, food that disagreed, a sun-and-cocktail combination that felt a lot like the flu the next morning. The news headlines about "200 people sick on a Carnival cruise" make norovirus sound like a rare disaster, but the reality on cruise ships is more pervasive and a lot less dramatic. The good news is that the same handful of habits that protect you from norovirus also protect you from most of the other ways a cruise vacation can go sideways. Here is what I tell every cruiser I know. #### #### Honest Advice I Give Clients About Staying Healthy On A Cruise Skip the noise, do these instead: - **Wash your hands first, then use sanitizer.** Soap and water actually destroy norovirus. Alcohol gel is a backup, not a substitute. The "Washy Washy" crew at the buffet entrance exists for a reason - use the station, not just the gel. - **Pick less-crowded ships and venues.** Norovirus needs density to spread. I love Virgin Voyages because there isn't really a buffet at all. Lines like Carnival and Norwegian have so many specialty venues that you don't need to pile into one room. - **Look up your ship's CDC score before you book.** The Vessel Sanitation Program inspection database is public at wwwn.cdc.gov/inspectionquerytool. Anything below 85 is failing. - **Be honest on the embarkation health questionnaire.** They can deny boarding, yes - but lying gets you and other people sick, and most travel insurance covers the alternative. - **If you see something that looks off, don't justify it.** Skip the grilled veggies somebody just sneezed on. Don't talk yourself into "it's probably fine." - **If you start feeling off, tell the medical team.** Don't tough it out in the dining room. The crew wants to stay healthy too. - **Planning a cruise and want a hand sorting through ships?** [Heather Hills at Flow Voyages](https://flowvoyages.com/) can [book a cruise](https://cruisewestcoast.com/book-a-cruise.html) with the kind of ship and itinerary that fits how you actually like to travel. #### Article Index [Norovirus on a Cruise: What the Headlines Get Wrong](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#norovirus-on-a-cruise-what-the-headlines-get-wrong)[Read the Ship's CDC Score Before You Book (and Know What Has Changed)](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#read-the-ships-cdc-score-before-you-book-and-know-what-has-changed)[What the 2025 CDC Cuts Mean for Cruise Health Reporting](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#what-the-2025-cdc-cuts-mean-for-cruise-health-reporting)[What I Actually Do on a Cruise to Stay Healthy](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#what-i-actually-do-on-a-cruise-to-stay-healthy)[What the Best Cruise Lines Do (and Where Even the Originator Has Wandered)](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#what-the-best-cruise-lines-do-and-where-even-the-originator-has-wandered)[When the Captain Calls Code Red](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#when-the-captain-calls-code-red)[The Embarkation Health Questionnaire is Not a Trick](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#the-embarkation-health-questionnaire-is-not-a-trick)[If You Get Sick on the Ship, Be a Good Cruiser](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#if-you-get-sick-on-the-ship-be-a-good-cruiser)[The Bigger Picture](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#the-bigger-picture)[If You Do Get Sick](https://cruisewestcoast.com/how-to-avoid-norovirus-on-a-cruise.html#if-you-do-get-sick) ## Norovirus on a Cruise: What the Headlines Get Wrong The "200 people sick on Carnival!" cable-news headline is real, and 2024 and 2025 have been a genuinely bad stretch - the CDC's Vessel Sanitation Program logged 19 gastrointestinal outbreaks across cruise ships by fall 2025, the worst single-year run in roughly 18 years. Specific ships took hard hits: Cunard's Queen Mary 2 had 224 passengers fall ill on a single April 2025 voyage; Holland America's Eurodam logged 148 cases; Royal Caribbean's Serenade of the Seas saw 94 cases in September 2025. Silversea's Silver Ray had a different one in January - an E. coli outbreak rather than norovirus. So yes, norovirus is real and it has been worse lately than it was a few years ago. That said, the news framing makes it sound like a rare catastrophe that strikes one ship in a thousand. The honest version is that [norovirus](https://cruisewestcoast.com/what-new-cruisers-need-to-know-about-avoiding-norovirus.html) and its close cousins - other gastrointestinal viruses, garden-variety food-borne bacteria, common respiratory bugs - are present on plenty of sailings without rising to the level of a CDC report. A cruise ship is essentially a Golden Corral with thousands of people sharing the same air, the same handrails, and the same ice scoop. The buffet is not inherently dirtier than your local hometown buffet. The difference is that when something does spread, it goes big fast. And it is not just norovirus. On any given cruise, a handful of people are dealing with food-borne illness from something they ate before they boarded, dehydration from drinking in the sun, exhaustion from staying up too late, or a stomach reacting to weeks of richer food than usual. They all feel a little like norovirus from the inside. The behaviors that protect you from one tend to protect you from most of them. ## Read the Ship's CDC Score Before You Book (and Know What Has Changed) The CDC Vessel Sanitation Program inspects every ship that calls a U.S. port and carries 13 or more passengers, twice a year, on an unannounced basis. Each ship starts with a score of 100 and loses points for every infraction the inspector documents - cracked ice machine, food held below temperature, broken sanitizer dispenser, dirty galley counter. Anything 85 or lower is a failing inspection. In 2025, 13 percent of inspected ships scored a perfect 100, and only one ship received a failing score across the whole year. What most cruisers do not realize is that the entire database is public. Every score, every report, every corrective action statement is on the CDC's website. Before I help anyone choose between two ships, I look up both. The query tool is at [wwwn.cdc.gov/inspectionquerytool](https://wwwn.cdc.gov/inspectionquerytool/InspectionSearchBasic.aspx) - search by ship name, cruise line, or date. A score in the 90s with consistent history is the comfort zone. Anything in the 80s warrants a second look at the report itself, not just the number, because some 86s are technical paperwork issues and some are actual sanitation breakdowns. ## What the 2025 CDC Cuts Mean for Cruise Health Reporting This is the part of the story that has changed in 2025 and that most cruisers are not aware of yet. In April 2025, the Trump administration's mass layoffs at the Department of Health and Human Services hit the CDC hard - more than 2,400 employees were terminated, and the entire Division of Environmental Health Science and Practice, which housed the Vessel Sanitation Program, was eliminated. Every full-time civilian VSP staff member lost their job. The program has gone from roughly 24 employees down to 12 U.S. Public Health Service officers expected to handle every cruise ship inspection at every U.S. port. The cuts were criticized across the political spectrum partly because the VSP is funded by fees the cruise lines pay, not by taxpayer dollars - eliminating the staff did not save the federal budget anything. Senator Richard Blumenthal and Representative Doris Matsui issued a formal joint protest. Erik Svendsen, who led the eliminated CDC division, told reporters: "None of the civilian staff are there to support them. So I don't know how long they will be able to sustain their mission alone without any support." What this means for cruisers in practical terms: - **Inspections are continuing**, but with half the prior staffing and no civilian support team behind the line officers doing the work. - **Outbreak investigations are degraded.** When a ship reports a GI illness cluster, the team that used to coordinate with state and local health departments, follow up on lab-confirmed cases, and track viral strains has been gutted. Outbreaks may still be reported, but the depth of analysis behind those reports has dropped. - **Public communications and database upkeep have been deprioritized.** The inspection query tool still works, but staff who maintain the website, post outbreak summaries, and answer media and public inquiries are largely gone. - **Reported numbers may understate reality.** A 3-percent threshold for outbreak reporting was already a high bar; with reduced investigation capacity, smaller outbreaks may not get documented at all. None of this means the system is broken or that you should avoid cruising. It does mean that the public reporting layer cruisers have leaned on for years is less reliable than it was a year ago. The practical advice: still look up your ship's most recent inspection score, but trust your own eyes and judgment on the ship more than you used to. The honest "every cruise has something" framing I opened with is a better mental model now than it was when the federal oversight system was fully staffed. ## What I Actually Do on a Cruise to Stay Healthy My personal protocol is not complicated, and it is the same protocol I tell every cruiser I know: - **I always carry hand sanitizer** - a small bottle in a pocket, refilled from the bigger one in the cabin. But I treat it as a backup. The handwashing stations at the buffet entrance are the actual job. - **I pick cruise lines and ships where the dining is spread out.** Virgin Voyages is the standout for me precisely because they made the choice not to have a real buffet at all. Their dining is across a half-dozen specialty venues, and you cannot wedge yourself into a single space sharing one tray of serving spoons with two thousand other people. Carnival and Norwegian also do well here on their newer ships - the buffet exists but there are so many other venues that you can simply avoid the peak-time crush. - **I avoid the buffet at peak times.** The 30-minute window right after passengers come back from a port day is the highest-density moment of any sailing. I either eat earlier, eat later, or eat somewhere else entirely. - **I do not justify suspect food.** If somebody sneezed on the grilled veggie tray ten seconds before I got to it, I skip the grilled veggies. The instinct to think "it is probably fine" is the wrong instinct on a cruise. Pass on it. There is more food a hundred feet down the line. - **I still wear a mask in crowded areas sometimes.** Not at the level we did right after the pandemic, and not at the dinner table - but in a packed elevator or a tight muster drill, sure. The social weirdness of it has mostly worn off, and nobody on a cruise ship is paying as much attention as you think. ## What the Best Cruise Lines Do (and Where Even the Originator Has Wandered) Norwegian Cruise Line deserves the original credit here. NCL launched the "Washy washy, happy happy" buffet-entrance greeter concept around 2008, turning what had been a finger-wagging reminder into something passengers actually engaged with. The whole industry's "make sanitation fun, not a nag" approach traces back to that NCL idea. Where it has gone since is a different story. Royal Caribbean adopted the concept and built it into a cultural moment - their "Mr. Washy Washy" crew members at the buffet entrance are now the most famous version of the bit, and one of them, Argel Symbol, became a minor internet celebrity for parodying pop songs into hand-washing reminders. The energy and the showmanship feel like a natural extension of what NCL started. Meanwhile, on a recent Norwegian sailing I had a guitar-wielding crew member roaming the buffet area, which I will charitably call... a creative interpretation of the original. The thing that made "Washy washy, happy happy" work is that it was brief and friendly: a smile at the door, you wash, you go. Trying too hard moves it from genuine reminder into background entertainment people tune out. NCL's heart is in the right place; the execution has wandered from the simplicity that made it effective in the first place. Carnival is solid on the operational side - hand sanitizer at every dining venue entrance, attentive crew at the buffet utensil swaps, fast cleanup of food spills. They do not have the showmanship of either line, but they get the job done. What frustrates me about all of this is that no matter how many good systems are in place, a meaningful chunk of cruisers walk straight past the handwashing station, give the sanitizer dispenser a quick squirt, and sit down to eat. Sanitizer is not enough on its own. Norovirus is a non-enveloped virus, which makes it stubbornly resistant to alcohol-based hand gels - the CDC has stated outright that alcohol sanitizer is largely ineffective against norovirus. Soap and twenty seconds of friction physically remove the virus from your skin in a way that alcohol cannot. The Washy Washy crew is not theater - they are an attempt to fix the chokepoint where the most cross-contamination happens, and the choice they are nudging you toward (the sink, not the dispenser) is the one that actually works. ## When the Captain Calls Code Red If a confirmed outbreak crosses the ship's threshold, the captain announces a Code Red - or whatever the line's specific term is for that level - and the operational picture shifts visibly within an hour: - The buffet stops being self-service. Crew take over every serving spoon. You slide a tray, point at what you want, and a gloved crew member plates it. - A dedicated crew member appears at the drinks station, handing out glasses of water, iced tea, or coffee so passengers are not touching the dispensers. - Salt and pepper shakers come off the tables and are replaced by single-serve packets. - The minute you leave a table, a crew member is on it with a bleach cloth. - Extra hand-sanitizer dispensers appear at every elevator, restaurant entrance, and choke point. - Public-area cleaning frequencies multiply. Every handrail, every doorknob, every elevator button gets sanitized on a much shorter cycle. - The captain comes on the PA system every few hours reminding guests to wash hands and report symptoms. If you are on a sailing when this happens, the right move is to fully cooperate. The crew is working overtime to get the ship back to baseline; the protocol works only if the passengers participate. It is also the moment to be most disciplined about your own hand-washing. The shipboard team can sanitize every surface twice a day, but they cannot wash your hands for you. ## The Embarkation Health Questionnaire is Not a Trick Every cruise line asks you to fill out a short health questionnaire at embarkation - have you had vomiting, diarrhea, fever, or respiratory symptoms in the last 24 to 72 hours. Cruise contracts give the line explicit authority to deny boarding to anyone presenting symptoms of norovirus, H1N1, or other communicable illness. People sometimes lie because they are afraid of losing the trip. Lying is the wrong call. If you are actively symptomatic, you are about to spread whatever you have to two thousand people in a confined space, and the math will catch up to you when you go to the medical center on day two. Most cruise lines will offer some form of future cruise credit if you self-disclose at the port. More importantly, this is exactly what travel insurance is for. A standard travel insurance policy will reimburse a missed cruise due to documented illness - and "documented" means a medical clearance you would have anyway. Honesty at embarkation is the cheaper outcome almost every time. ## If You Get Sick on the Ship, Be a Good Cruiser Twice in my own cruising history I have ended up at the ship's medical center, including a recent [Virgin Voyages](https://www.virginvoyages.com/book/voyage-planner/find-a-voyage?agentId=20843&agencyId=422) sailing on Brilliant Lady where several passengers came down with what looked like a food-borne illness. The medical team handled it well - thorough, calm, clear communication, no judgment. Cruise medical staff are excellent and they have seen everything. The right thing to do if you start feeling off is to go talk to them. The wrong thing is to hide it, hope it passes, and keep walking around the ship. Reporting yourself isolates the spread early. The crew can quarantine you in your cabin (yes, that part is real), bring you room service, monitor symptoms, and most importantly stop the chain of infection before it doubles. Cruise lines are not punishing - the protocols exist because the industry learned the hard way over decades. The crew genuinely wants to stay healthy too. They live on the ship. ## The Bigger Picture Cruise buffets are not inherently more dangerous than the buffet at your local Golden Corral. The pathogens are the same; the hand hygiene is the same; the opportunities for cross-contamination are the same. The difference is scale. When something starts spreading on a 4,000-passenger ship in international waters, it goes big fast and the news cycle picks it up. When the same thing happens at a roadside buffet in suburbia, twenty people get sick and nobody calls CNN. That asymmetry is exactly why cruise lines have invested so heavily in sanitation infrastructure that most land-based restaurants have not. Twice-yearly CDC inspections, dedicated handwashing crew, escalation protocols when an outbreak crosses a threshold, full-ship deep cleans between sailings. The system works when the passengers participate. Almost every cruise is uneventful. You can avoid the bugs you do encounter by doing the simple things consistently. ## If You Do Get Sick For what to actually do when you have already caught something on a cruise - cabin protocol, when to call the medical team, the cabin-cough phenomenon, post-cruise recovery - see our companion piece: [What to do if you get sick on a cruise ship](https://cruisewestcoast.com/what-to-do-if-you-catch-a-cold-on-a-cruise-ship.html).
