The most recent occurred in June on a Viking Cruises ship from Iceland that docked in New York, where 110 passengers and eight crew members fell ill. Secondly, clean and disinfect high touch surfaces such as doorknobs, faucets, handles, and that statue of Dwayne “The Rock” Johnson in the dining hall. Use either a chlorine bleach solution that has a concentration of at least 1,000 to 5,000 parts per million or use a disinfectant that’s registered with the Environmental Protection Agency (EPA) as being effective versus norovirus. And this year’s outbreaks represent the highest number since cruises began sailing again in the summer of 2021 after being suspended due to COVID-19.

In January 2016, the CDC issued travel guidance on affected countries and suggested using enhanced precautions and even postponing travel. Similar travel warnings were issued by other health agencies and governments. The ship includes multiple kitchens, grills and even an interactive space where guests can cook with Compton.
The Looming Marburg Crisis: How Virus Outbreaks Escalate and Spread
Such viral/bacterial outbreak incidents affect the vacation experience of thousands of people, being packed up in a floating resort for many days on end. In confined spaces with frequent passenger turnover (like big capacity cruise ships), it is easy for diseases to spread - whether food- or air-borne, or otherwise. There have currently been 13 norovirus outbreaks on cruise ships in 2023. The most recent outbreak occurred on a Viking Cruises ship, which traveled from Iceland and docked in New York City. About 13% of its passengers and several crew members became ill with the virus while on board.
Environments Where Norovirus Spreads Quickly
Once you have been exposed to Norovirus, it takes anywhere from one to three days for its symptoms to appear. Symptoms typically last only 24 to 48 hours but keep up the good hygiene for longer; people may be contagious for as long as two weeks after recovery. While having the symptoms of norovirus can be uncomfortable, they tend to be very short-lived and something that many people recover from in just a few days with over-the-counter medications. “Norovirus is one of the few viruses that doesn’t get deactivated by alcohol. You actually need to use soap and water to physically destroy it and remove it from your hands,” Ostrosky previously told TODAY.com. Norovirus can also get into food before, during or after preparation, and it's the top germ causing foodborne illness in the U.S., per the CDC.
The CDC's "Vessel Sanitation Program" is for monitoring illness outbreaks on passenger ships carrying 100 or more guests on sailings from 3 to 21 days in length. This is done 24 hrs prior to arrival at any US port of call from a foreign port. Norovirus can be especially challenging to control on cruise ships because of the close living quarters, shared dining areas, and rapid turnover of passengers. When the ship docks, norovirus can be brought on board in contaminated food or water or by passengers who were infected while ashore. Repeated outbreaks on consecutive cruises may also result from infected crew or environmental contamination.

Norovirus outbreaks 2023 reports
Coast guard helicopter teams fly to the ship, hoist the passenger (accompanied by a spouse/relative and a crew nurse) and fly them to the nearest land hospital. Norovirus on ships is spread through contaminated water, foods and surfaces (public restrooms, railings, doorknobs, handles, board games-cards-puzzles-toys, etc). Norovirus withstands chlorine, prolonged exposure outside the body, as well as temperature extremes. Like a virus, Norwalk can't be effectively treated with antibiotics, making it extremely difficult to eliminate in closed environments - like cruise vessels. The most recent outbreak hit passengers and crew members on board a Viking Cruises trip from Iceland that docked in New York on June 20. More than 13% of passengers on the Viking Neptune — 110 of 838 in total — reported being ill while onboard, according to the CDC.
“The health and safety of our guests, crew, and the communities we visit are our top priority,” a spokesperson for Silversea Cruises told The Post in a statement. Nearly 30 people aboard a luxury cruise liner known for its phenomenal cuisine have fallen ill thanks to a gastrointestinal outbreak that swept through the ship. Even though you may be tempted to conceal your illness, you would be doing a great disservice to the other passengers and the crew on the cruise by keeping it a secret. She noted that hand sanitizers do not work well against norovirus and that they are not a substitute for handwashing. Typically, norovirus lasts for one to three days, though you can spread the illness for a few days after. Cruise lines employ crews dedicated to keeping public areas and high-touch surfaces clean.
At the cruise ship's Infirmary, and also at Reception Desk is provided (free of charge) Meclizine. Also, motion in midship-located areas (including staterooms) is highly reduced in comparison to forward and aft areas. To try to help prevent the spread of stomach viruses at sea, the CDC randomly inspects cruise ships and scores them on a scale of 0 to 100 through the Vessel Sanitation Program. Inspection scores of 85 and lower are considered "not satisfactory" by the agency. The CDC estimates only about 1% of all annual U.S. norovirus cases happen on cruise ships. The numbers are greatest in nursing homes, hospitals, schools and restaurants, which collectively account for about 91% of cases.

Each company has its own standards provided for its passengers' healthcare. The symptoms are nausea, vomiting, diarrhea, indigestion, abdominal cramps. The illness lasts 1 to 4 days, but some people (especially elderly) may be contagious for up to 2 weeks after recovery. In the past 10 years, only three other cruise ships have received sanitation scores below 70, CDC records show.
The Centers for Disease Control and Prevention said 28 of Silver Nova’s 633 guests reported being ill during a voyage that began on March 31, along with one of the vessel’s crew members. If you have norovirus illness, the CDC recommends you drink plenty of liquids to replace fluid lost from vomiting and diarrhea and help prevent dehydration. Cruise lines are not required to compensate passengers who fall ill on a voyage; however, cruise lines will generally compensate passengers whose voyage is altered or canceled due to an outbreak. Norovirus is named after an outbreak that occurred in Norwalk, Ohio, in the late 1960s. “While many viruses and illnesses cause a fever, norovirus does not always cause one,” said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center in Tennessee.
In response to the reported cases onboard, crew members aboard Silver Nova have immediately implemented enhanced sanitation and other measures to minimize any further spread. Norovirus outbreaks also frequently occur in schools, childcare centers, colleges, and universities. Norovirus outbreaks on school and university campuses have even led to campus closures. Close quarters, shared spaces, and high-touch surfaces make it easy for norovirus to spread in schools.
Most of these outbreaks occur in food service settings like restaurants. Infected food workers are frequently the source of outbreaks in food-service settings, often by touching ready-to-eat foods, such as raw fruits and vegetables, with their bare hands before serving them. However, any food served raw or handled after being cooked can get contaminated with norovirus.
Numerous studies confirm that a quick application of hand sanitizer doesn't kill the Norovirus. It takes about 30 sec of hard rubbing with hot water and soap (including under the nails) to wash it. Most vessels have received scores in the high 90s — only one cruise ship, the MSC Seaside, has failed the CDC's sanitation inspection so far this year. The vessel received an unusually low score of 67, nearly 20 points below the agency's passing grade.
The total number of infected was 2535 (of those 2450 passengers and 85 crew). In 2018, the number of reported illness outbreaks on cruise ships was 15. The total number of infected was 1177 (of those 1099 passengers and 78 crew). In the following table, you can see all 2019-reported Norovirus outbreaks on cruise ships.
That means data for norovirus on cruise ships is more readily available than for other entities. It's easy to make norovirus case numbers sound alarming, but context matters. For example, 100 cases on a single ship might seem like a lot, but on a vessel like Oasis of the Seas, which carries more than 5,400 passengers, 100 cases are only about 2% of the onboard population.
First and foremost, wash your hands often with hot water and soap; the CDC recommends hitting the sink before and after eating and smoking, after touching your face, after using the restroom, and whenever your hands are dirty. Limit person-to-person contact as much as possible (we're not saying you absolutely must refuse the captain a handshake at his cocktail party ... just use your judgment throughout the cruise). It only takes a small number of virus particles for norovirus to spread, which is why norovirus causes so many explosive outbreaks, Ko previously told TODAY.com. Some cruise lines offer hand-sanitizer dispensers near the ship's restaurants, Lido/pool deck areas and other more crowded public spaces in their effort to keep a lid on sickness outbreaks. There's nothing like a stomach virus to ruin your vacation, as hundreds of cruise ship passengers have unfortunately learned this year.
