You can also get a low-grade fever, chills, a headache, and muscle aches. Such symptoms tend to emerge rather suddenly about one or two days after the virus has gone down your pie hole. 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. An "illness outbreak" is considered when 3% or more of all passengers report symptoms to the ship's med staff.

Hospital ships are designated as floating medical facilities (hospitals). Seasickness manifests in different ways and is always a result of the body's attempt to correct for the conflicting inputs received from its senses. Common symptoms are cold sweat, dizziness, drowsiness, headache, nausea. When such symptoms are noticed, passengers should take precautions to prevent intensifying the disorientation.
CDC cruise ship Norovirus reports
Data on outbreaks on cruises is available starting from 1994, and the rate of incidence has diminished significantly since it reached a peak in the early 2000s, when outbreaks regularly surpassed 20 per year. Shipboard medical service fees vary and are usually set by medical practitioners. In most cruise ship hospitals, some supplies and medications are provided to passengers and crew for free - like aspirin, seasickness pills, small bandages. A cruise ship's medical facility can treat only passengers experiencing minor health issues - seasickness, scrapes, sunburns, etc.
Norovirus outbreaks on cruise ships
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. Norovirus is highly contagious and can spread directly through sick people and contaminated surfaces, food, or drinks.

The most severe outbreaks were reported in Brazil, with an alarming surge in newborns with microcephaly. If the mother is infected, the virus may cause microcephaly in newborns. This is a neurodevelopmental disorder - babies are born with an underdeveloped head. Quarantining the ill passengers and crew to their cabins is mandatory (at least for 48 hours) to slow the outbreak's spread.
Basic medical care on cruise ships
What causes Norovirus on cruise vessels is mainly contaminated food/water. When it comes to ships, it spreads mostly through physical contact with sick people or handling contaminated objects. This includes sharing food/utensils and poor hygiene (not washing hands after bathroom use).

Yeah, even though norovirus is known as the “Winter vomiting bug,” it’s activity is not necessarily confined to the colder months. There have already been an unlucky 13 recorded norovirus outbreaks on cruise ships under U.S. jurisdiction so far in 2023. 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. 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.
Purchasing cruise travel insurance with health coverage (medical clauses) is highly recommended. If seasickness symptoms are accompanied by diarrhea or fever, passengers should immediately seek medical treatment for Norovirus and avoid spreading the illness to others. 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. VSP may also post information on gastrointestinal illness outbreaks of public health significance that do not necessarily meet the above criteria.
Seasickness on cruise ships
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. You may hear about it on your local radio station, or on your local cable operator, but not necessarily on ABC, CNN, and often not even on Yahoo and MSN news online. It's not about the passengers' health (never been) - it's about the big money that rules our world.
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. 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.
Virus particles can contaminate drinking water that isn't treated properly or pools when people poop in the water. However, as travel surges this summer, travel-related illnesses are expected to surge, as well. “I think our travel frenzy after COVID is partially fueling this continued spread (of norovirus),” says Ostrosky.
Close living quarters, shared bathrooms, populated pools, busy buffet lines and rapid turnover of passengers make it difficult to control the spread of the virus once it hits a ship. “It’s just really the perfect scenario for transmission of highly contagious GI [gastrointestinal] pathogens,” Lucar says. The New York Post reported that the Silversea outbreak was the fourth this year, including one that saw 130 people struck with diarrhea and vomiting and another that saw 104 passengers fall ill on a Holland America liner. The cause of the outbreak is still unknown, but the agency noted that noroviruses are typically caused by eating contaminated food or drinking contaminated water. The cruise industry shut down during the pandemic, and as such there were no outbreaks of gastrointestinal illness reported in 2020, and one in 2021 as trips started up again. As part of its Vessel Sanitation Program (VSP), the Centers for Disease Control and Prevention (CDC) tracks occurrences of gastrointestinal disease on board, which cruises are required to report.
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. In 2014, Zika spread across the Pacific Ocean to French Polynesia, and soon to Easter Island. In 2015, Zika virus reached Central America, the Caribbean, and South America. Obviously, the first thing is to go to the ship's infirmary (medical center) and contact the doctor.
Another popular cruise line, Royal Caribbean International, has reported four outbreaks since January. Respiratory infectious outbreaks on cruise ships may be caused by a range of pathogens including SARS-CoV-2 (the virus that causes COVID) and influenza viruses. These can be spread by respiratory droplets and aerosols released when people breathe, talk, laugh, cough and sneeze. The same number of sick bug outbreaks on cruise ships have been reported so far this year than in the entirety of both 2017 and 2018, when there were 11 in total. As the CDC notes, millions of people travel on cruises every year, making less than a dozen outbreaks a relatively minor concern. So outbreaks are found and reported more quickly on a cruise ship than on land,” says the CDC.
Health officials at the CDC determined that norovirus caused the outbreak after Viking Cruises collected and sent specimens to the agency's laboratory for testing. For passengers with health concerns, medical care on cruise ships is a vital part of their travel planning. Most cruise vessels are equipped with either basic infirmary (a small clinic) or larger hospital where sick or injured passengers are treated and cared for by contractor physicians and nurses on 24-hour duty. 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.
But before going on your next cruise adventure, it doesn't hurt to check out the ship's most recent sanitation rating. Find more information about gastrointestinal illness outbreaks on land and at sea. Other passengers were notified, and crew members "increased cleaning and disinfection procedures." Workers aboard the ship aim to show guests "outstanding gastronomy," according to the Silversea website. At the end of last year, "Top Chef's" Nina Compton joined its staff, and offered personal cooking lessons to passengers. On cruise ships, people tend to crowd together in confined spaces for extended periods.
