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. The simple answer is that cruise ships are required to report cases of acute gastroenteritis to the CDC, even when the numbers are low.

These reports are requested by completing the Cruise Ship Cumulative Acute Respiratory Illness (ARI) Reporting Form. Access to the online reporting form has been provided to cruise lines by CDC. Norovirus is a highly contagious virus that causes acute gastroenteritis, which is inflammation in the stomach or intestines, according to the CDC.
Norovirus Cases Are Rising on Cruises. Here’s How You Can Stay Safe
Cruise experts say several factors may be contributing to the rise in cases. For one, cruising has soared this year, with the number of passengers expected to surpass the total that sailed in 2019, according to the Cruise Lines International Association. 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. [2] Confirmed influenza means laboratory confirmation for influenza A or B by viral test. 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.
How common is it?
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). 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).
Outbreaks 2018 reports
Passengers sensitive to nausea or motion sickness should consult their doctors for medical recommendations prior to departure. 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. Norovirus on ships is spread through contaminated water, foods and surfaces (public restrooms, railings, doorknobs, handles, board games-cards-puzzles-toys, etc).
Each company has its own standards provided for its passengers' healthcare. Shipboard hospitals as facilities and equipment vary by cruise line and vessel. Clinic's size usually depends on the ship's capacity (passengers plus crew). Generally, bigger and newer ships offer larger and better-equipped medical facilities and are served by bigger infirmary staff. If seasickness symptoms are accompanied by diarrhea or fever, passengers should immediately seek medical treatment for Norovirus and avoid spreading the illness to others. So it comes as no surprise that when CDC reports an illness outbreak on some vessel, big media sources do not immediately (or ever) respond to the news.

In general, molecular tests are recommended over antigen tests because of their greater sensitivity; multiplex assays are available that can detect SARS-CoV-2, influenza A and B, and RSV. Cruise ship operators should consider performing viral testing (e.g., COVID-19, influenza, RSV) for passengers with ARI before they embark. The CDC says crew on the ship, which can carry more than 2,100 passengers, increased cleaning and disinfection procedures and collected stool specimens to send to a lab to confirm the cause. On most vessels, the medical facilities are located midship on a lower deck (for easier access and better stability) and usually among other crew facilities. Every passenger stateroom has the Infirmary's number - posted or by the cabin's phone.
The CDC writes that people who are infected "can shed billions of norovirus particles that you can't see without a microscope," and exposure to just a few norovirus particles can make someone sick.

There's nothing like a stomach virus to ruin your vacation, as hundreds of cruise ship passengers have unfortunately learned this year. As part of the program, ships are required to adhere to stringent health and safety protocols that dictate everything from the cleaning of high-touch areas to how food is stored in freezers, refrigerators and galleys. 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.
How to prevent seasickness on cruise ships (tips)
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. During COVID, the options for cruises were limited, but now that restrictions have been lifted, more people are deciding to take that cruise they had been putting off.
The illness lasts 1 to 4 days, but some people (especially elderly) may be contagious for up to 2 weeks after recovery. A norovirus outbreak can cause significant disruption to the planned activities and itineraries of a cruise. Infected individuals must be isolated, common areas may need to be closed for cleaning, and in severe cases, the ship may even have to return to port.
Usually, a pre-embarkation health advisory is distributed to all boarding passengers. Additional med staff is sent to the ship in port to assist the disembarkation of infected passengers. Another possibility is the cruise ship to cancel all the itinerary's foreign ports of call and to return to its US home-port before the end of the voyage.
P&O Cruises also reported an outbreak on its Arcadia cruise ship this year. 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. 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.
Vessel captains may request assistance from CDC to evaluate or control ARI outbreaks as needed. If the ship will not be arriving imminently at a U.S. seaport, CDC maritime staff will provide guidance to cruise ship officials regarding management and isolation of infected people and recommendations for other passengers and crew members. 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 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 design and operation of cruise ships often involve large groups of people living in close proximity, sharing dining areas, entertainment spaces, and public restrooms.
