During its June 6 to June 20 voyage, 110 of the ship’s 838 passengers, or 13.1 percent, were infected. The bug thrives in crowded conditions and is spread through food and by touching contaminated surfaces. The easiest way to avoid the ailment is to wash your hands with soap and water after using the bathroom, before eating and after touching surfaces touched by others.
As the Cruise Industry Makes a Comeback, Norovirus Outbreaks Are on the Rise
The following "health advisory" list of recommended actions is often issued during gastrointestinal illness outbreak or on embarkation day (of the next scheduled voyage). It has important suggestions on how to avoid spreading the cruise ship virus infection. CruiseMapper's Norovirus survey is based on official data from CDC.gov (USA's "Centers for Disease Control and Prevention"). CDC's "Vessel Sanitation Program" assists the cruise tourism industry in preventing and controlling the transmission and spread of gastrointestinal illnesses (Norovirus, ETEC) on passenger ships calling on US seaports. If you feel ill from Norovirus while on a cruise ship, visit the ship's doctor.
Norovirus Cases Surging on Cruise Ships, What are the Signs and Symptoms
This step helps them minimize the risk of spreading the disease to others. Some people find getting tested for norovirus embarrassing, while others only have stomach virus symptoms for a few days and do not seek medical care during that time. In April 2023, a multistate norovirus outbreak was linked to raw oysters from Texas, according to the CDC.
When was the most recent norovirus outbreak on a cruise ship?
This alarming number marks the highest incidence of such outbreaks since 2012 when there were 16 across eight lines over the entire year. The allure of the open sea, captivating itineraries, and the luxurious promise of a carefree escape have long made cruising a popular choice for vacationers. However, this industry’s lustrous appeal has recently been overshadowed by a surge in outbreaks of a particularly stubborn and contagious pathogen — Norovirus. 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 disinfecting product and technology were developed by the Danish company ACT Global AS (Copenhagen). The spray is chemical-free, odourless, transparent and can be applied to all surfaces. 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. Quarantining the ill passengers and crew to their cabins is mandatory (at least for 48 hours) to slow the outbreak's spread.
Norovirus Cases Are Rising on Cruises. Here’s How You Can Stay Safe
Stick to bottled water, and don't share drinking glasses and eating utensils. We'll be in your inbox every morning Monday-Saturday with all the day’s top business news, inspiring stories, best advice and exclusive reporting from Entrepreneur. An MSC Cruises representative told Insider at the time that the cruise line had launched an internal investigation based on the inspector's concerns and taken immediate corrective actions. Norovirus is very contagious, but you can take steps to stop it from spreading. Symptoms usually last one to three days and most people recover, according to the Mayo Clinic. So if you're planning to set sail this summer, here's everything you need to know about the norovirus.
On ships where outbreaks occur, the crew conducts a deep cleaning of the ship after passengers have disembarked and before the next sailing begins. In cases where outbreaks are particularly severe, subsequent sailings could be canceled to allow for more thorough sanitization. "The opportunities for close person-to-person spread are so intense on a cruise ship that once this virus is introduced into that population, it has many, many opportunities to spread," Schaffner warned. Even when compared to pre-pandemic levels, the number of outbreaks in 2019 was eight for the entire year — a figure that 2023 has already surpassed with five months still remaining.
In 2016, the number of reported illness outbreaks on cruise ships was 23. The total number of infected was 2504 (of those 2378 passengers and 126 crew). In 2017, the number of reported illness outbreaks on cruise ships was 21. The total number of infected was 2535 (of those 2450 passengers and 85 crew).

Norovirus Cases On Cruise Ships Skyrocket: Here’s Why—And How To Avoid Getting Sick.

A total of 130 crew had gotten sick on those voyages and didn't report their illness in the required time period. The threat of norovirus on cruise ships is a serious issue that has both health and economic impacts. 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.
During that time frame, approximately 127 million passengers sailed on the 252 cruise ships under VSP jurisdiction. 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. Hand hygiene is key to prevent the spread of the highly contagious virus — but the way you clean your hands matters, experts note. It has to be with soap and water, because alcohol-based hand sanitizers are not effective against norovirus.
Though generally moderate, symptoms are often flu-like (in fact, Norovirus is often called the "stomach flu," even though it is not related to influenza). Symptoms include nausea, vomiting, diarrhea and abdominal cramps; children often vomit more than adults. Infected passengers who don't wash their hands after coughing, sneezing or using the restroom are the reason those surfaces become contaminated in the first place. 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.
You might also hear it generically called a stomach bug or the stomach flu despite the fact that noroviruses are not the same as flu viruses. 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. The following statistics show the number of cruise ship illness outbreaks in recent years. You can compare the number of reports (CDC and news media sources) and the total number of infected (passengers and crew). Norovirus spreads easily in close quarters, such as those found on cruise ships.
While this virus tends to be short-lived, treatment is based on symptomatic care. And recent data from the CDC has noted that over 15% of norovirus tests are coming back positive. Surfaces or objects that are contaminated with norovirus can be cleaned with a high-level disinfectant like bleach, per Ostrosky. Attacking a hospital ship is considered a war crime, but enemy forces have the right to board them for inspections. Seasickness is physical disorientation as a result of conflicting signals received by the brain from different body senses. Our inner ear senses the ship's irregular motion, which our eyes can't see because the floor and walls are stable.
The most effective way to prevent norovirus on a cruise is with regular and thorough handwashing. It is particularly important that you do this after using the bathroom and before and after eating, drinking or smoking. As the world emerges from the pandemic, the cruise industry is experiencing a resurgence in demand.
