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. However, there's a tendency to cover up the severity of this issue.
Outbreaks 2016 reports
Norovirus is typically spread by ingesting small particles of fecal matter, eating contaminated food, touching contaminated objects or surfaces and then touching the mouth or eyes, or having direct contact with an infected person. An infected person is the most contagious when symptoms are present and within the first few days of feeling better. According to the Minnesota Department of Health, symptoms of norovirus infection include vomiting, nausea, diarrhea, stomach pain, muscle aches, low-grade fever and headache.

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. What’s more, the CDC has established a rigorous Vessel Sanitation Program (VSP) to help prevent the overall spread of illnesses on cruise ships. Not only do they inspect a cruise ship’s medical center, but they also monitor their portable water systems, dining rooms, housekeeping procedures, heating, ventilation, air conditioning (HVAC) systems, and more. The most common symptoms of norovirus are vomiting, nausea, diarrhea and abdominal pain, Dr. Albert Ko, infectious disease physician and professor of public health, epidemiology and medicine at Yale School of Public Health, tells TODAY.com. The number of outbreaks in the first six months of 2023 is higher than the yearly total during every year since 2012, when there were 16 outbreaks on cruise ships reported to the CDC.

The United States is not alone in this increase in norovirus cases. Ferry's train deck was reconstructed and converted into a hospital. The ship project started in March 1999 with the vessel's acquisition through a donation from Balcraig Foundation (UK), which purchased the boat for US$6,5 million. Search for medical assistance - consult the ship's physician if no actions provide relief.
Norovirus outbreaks spiked on cruise ships this year, with data showing more outbreaks happened between January and June than over the course of any other full calendar year in the last decade. Thirteen norovirus outbreaks have been reported on cruises so far in 2023, according to the U.S. Centers for Disease Control and Prevention, which keeps a record of annual case counts dating back to 1994. 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.
Why do I only hear about Norovirus outbreaks on cruise ships?
When Norovirus outbreaks can't be contained, cruise lines might also pull the ship out of service for a few days for sanitizing. 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. Here are listed latest cruise ship Norovirus outbreaks on passenger ships, with information what is and how to avoid Norovirus on cruise ships, CDC reports, and news updates.
Norovirus Cases On Cruise Ships Skyrocket: Here’s Why—And How To Avoid Getting Sick
Similarly, you’ve got to be careful about anything that could explode in your pants. The key to preventing norovirus, and most other illnesses is simply washing your hands well. According to the CDC, the most common symptoms of norovirus are diarrhea, vomiting, nausea and stomach pain. This may explain why so many people of all ages get infected during norovirus outbreaks. A norovirus outbreak can cause significant disruption to the planned activities and itineraries of a cruise.

If you feel ill from Norovirus while on a cruise ship, visit the ship's doctor. Additionally, be sure to drink plenty of water, as dehydration is a common side-effect. If passengers report symptoms, they are typically quarantined to their cabins to prevent spreading the illness to others -- not an ideal situation, but necessary. The CDC regularly inspects cruise ships and monitors the number of outbreaks. This year, norovirus also has been reported on cruises operated by Royal Caribbean International, Celebrity Cruises, Princess Cruises, Holland America and P&O Cruises. The worst year for norovirus was 2006, when 32 ships reported infections, according to the CDC.
“You must be diligent beyond your common understanding of when to wash your hands, because there are millions of norovirus particles spreading in various areas,” Boden-Albala says. “We believe the gastrointestinal illness originated from a shoreside restaurant in Iceland where a group of guests dined during their free time,” the cruise line said in a statement. After docking in New York, the ship was thoroughly cleaned and disinfected, and continued its scheduled sailings. Mathis says older passengers and others traveling with family face a risk from others in their party. For example, if grandchildren aren’t careful hand-washers, they can easily infect their grandparents and others. As 95 of the world's top 100 largest megapolises are port cities, "hospital ships" could provide healthcare very quickly and more efficiently to large numbers of people.
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. They are located on upper decks and include cabins for families, couples and single cabins. Attacking a hospital ship is considered a war crime, but enemy forces have the right to board them for inspections. In January 2016, the CDC issued travel guidance on affected countries and suggested using enhanced precautions and even postponing travel.
The CDC has tracked outbreaks of gastrointestinal illness on cruise ships through its Vessel Sanitation Program (VSP) since 1994. It’s really not that surprising that norovirus outbreaks have already reached a high water mark this year. As many Covid-19 precautions went the way of sweater vests in late 2022, it’s probably not a coincidence that this past winter saw a surge of norovirus cases in general, as I reported for Forbes on February 10, 2023. On top of that, cruise ships returned to full operations for the entire calendar for the first time since early 2020.
VSP inspectors board ships and conduct thorough checks to ensure compliance, and the standards are high. You can find a list of the most recent inspection scores and lists of violations for each ship on the VSP website. Be sure to read your contract -- on the back of your cruise documents or ticket -- very carefully.
Zika virus (aka ZIKV) is a Flavivirus - from the genus of the viruses named West Nile, dengue, tick-borne encephalitis, yellow fever. These plus several other viruses may cause encephalitis (acute brain inflammation). In humans, Zika virus causes the Zika fever which is known to occur only within some equatorial regions.
