That’s the highest tally in 10-years, ever since 16 such outbreaks occurred in 2012, according to the Centers for Disease Control and Prevention (CDC) Vessel Sanitation Program. And with half of 2023 still to go, there’s a good chance that the 2012 count will be surpassed sometime later this year. Norovirus is a highly contagious virus that causes acute gastroenteritis, which is inflammation in the stomach or intestines, according to the CDC. Health officials say norovirus is the most common cause of vomiting and diarrhea as well as the most common type of foodborne illness.

Learn more about illnesses and outbreaks reported to VSP and find information about outbreaks of gastrointestinal illness on cruise ships. In 2012, the number of reported illness outbreaks on cruise ships was 34. The total number of infected was 5542 (of those 5079 passengers and 463 crew). In 2013, the number of reported illness outbreaks on cruise ships was 22. The total number of infected was 2385 (of those 2249 passengers and 136 crew).
How does norovirus spread on cruise ships?
According to the Cruise Lines International Association, cruise passenger volume is estimated to reach 106% of 2019 levels this year, with 31.5 million passengers expected to set sail. Norovirus infects between 19 million and 21 million Americans annually, the CDC reports. 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.

What do cruise ships do to prevent norovirus outbreaks on board?
The confined environment of a cruise ship, combined with the virus’s highly contagious nature, creates a significant challenge. It’s crucial for cruise lines, passengers, and health officials to remain vigilant, proactive, and informed to prevent and contain potential norovirus outbreaks. 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. This protocol only confirms that the CDC knows everything about it.

2024 Is Already Shaping Up to Be the Year of Cruise Ship Norovirus Cases - Matador Network
2024 Is Already Shaping Up to Be the Year of Cruise Ship Norovirus Cases.

The navies of USA, UK, Australia, China, France, Italy, Spain, Argentina, and Japan have some classes of military ships fitted with onboard hospitals. Most hospital ships are navy vessels (operated by military forces) which are specifically built for use in war zones. Based on the math, you have less chance of catching a gastrointestinal illness on a ship than at many places you're likely to visit on land.
Norovirus outbreaks 2022 reports
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. An excessive number of news reports exist for norovirus cases on ships, making it seem to the unsuspecting public that cruise vessels are dirty or you're likely to get sick if you sail. The Centers for Disease Control and Prevention (CDC) reported a gastrointestinal viral outbreak that sickened several cruise ship guests earlier this week.
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). It’s really not that surprising that norovirus outbreaks have already reached a high water mark this year.

This includes sharing food/utensils and poor hygiene (not washing hands after bathroom use). The virus also spreads fecally, so you can catch it into the onboard laundry, or while changing diapers, etc. However, many passengers likely can blame a sick crewmember for the virus. According to a survey based on 170 inspection records on ships that docked in Florida ports in 2012, on 59 cruises violations of the required illness reporting laws were reported. A total of 130 crew had gotten sick on those voyages and didn't report their illness in the required time period. There are more than 21 million US cases reported annually, of which 1 mill related to kids.
How to avoid Norovirus on cruise ships?
In some cases, nearby ships with better medical facilities may assist. There are no internationally specified regulations governing ship infirmaries and medical staffing. Each company has its own standards provided for its passengers' healthcare.
Outbreaks happen mostly during winter months and mainly in more crowded places with close quarters. Among those are schools, hospitals, nursing homes, dormitories, prisons, big resorts, bigger passenger ships (including cruise ferries). Norovirus is often branded as "cruise ship virus" simply because on ships health officials are required to report every gastrointestinal illness incident. This means Norovirus outbreaks are reported more quickly on ships than on land.
Of those 127 million cruisers, 26,450 reported symptoms of gastrointestinal illness while on board. It sounds like a large number, but it amounts to just 0.02% (two one-hundredths of one percent) of cruisers throughout those 14 years, with the total number of cases decreasing from 4,507 in 2006 to 1,201 in 2019. On cruise ships, health officials are legally required to track any illnesses that occur, while this same reporting is not required on land. For this reason, the Centers for Disease Control and Prevention note that outbreaks are reported more frequently on sea than on land. The Centers for Disease Control and Prevention is reporting the highest number of norovirus outbreaks in over a decade and it is impacting hundreds of passengers and crew members onboard some of the most prominent cruise lines. Outbreaks of the stomach bug have surged on cruise ships this year, reaching the highest levels seen in 10 years.
In the following table, you can see all 2019-reported Norovirus outbreaks on cruise ships. The listed statistical data is based on CDC or news media reports. It shows the number of sick passengers and crew (with the respective percentage to all), along with the corresponding CDC report pages (if available) as outgoing links. Among 410 reported cases during November 2022–January 2023 (voyages 1–5), 356 (87%) occurred in passengers and 54 (13%) in crew members. The index case likely occurred in a food and beverage crew member sailing on a crew-only voyage (voyage 1).
