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. Additionally, the CDC's Vessel Sanitation Program, implemented in the 1970s, subjects all passenger ships carrying 13 or more people to random, unannounced inspections if they wish to call on ports in the United States. Even though you may be tempted to conceal your illness, you would be doing a great disservice to the other passengers and the crew on the cruise by keeping it a secret. She noted that hand sanitizers do not work well against norovirus and that they are not a substitute for handwashing. Typically, norovirus lasts for one to three days, though you can spread the illness for a few days after.

Find more information about gastrointestinal illness outbreaks on land and at sea. In cases of severe emergencies, passengers with life-threatening illnesses or injuries are evacuated off the ship - either by boat (if in or near seaport) or by rescue helicopter dispatched from nearest coast guard or other station. In some cases, nearby ships with better medical facilities may assist. In February 2020, the shipowner cruise company Lindblad Expeditions announced the "Premium Purity" program with a shipwide cleaning system based on ACT CleanCoat technology. The innovative ship cleaning process is based on photocatalytic antibacterial spray that when activated by light kills viruses, bacteria, airborne microbes, mould. The disinfecting product and technology were developed by the Danish company ACT Global AS (Copenhagen).
Norovirus outbreaks on cruise ships
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. More severe medical emergencies can't be handled on the ship and usually require medevacs. Coast guard helicopter teams fly to the ship, hoist the passenger (accompanied by a spouse/relative and a crew nurse) and fly them to the nearest land hospital. Other possible actions and results are red level ("Code Red") cleaning. The boarding/embarkation of new passengers is often delayed to permit more extensive disinfection of public areas and the cabins.
As the Cruise Industry Makes a Comeback, Norovirus Outbreaks Are on the Rise
According to the American College of Emergency Physicians (ACEP), every cruise ship must have a place to isolate any passengers who have a contagious disease. This step helps them minimize the risk of spreading the disease to others. In serious cases where outbreaks cannot be contained, cruise lines might actually pull a ship out of service for a few days so it can undergo a more thorough sanitization. The cause of the gastrointestinal illness was not known, health officials said, but they added that the main symptoms among those on board the vessel included diarrhoea and vomiting. You are at your most contagious when you have symptoms of norovirus illness, especially vomiting or during the first few days after you feel better.
URL addresses listed in MMWR were current as of the date of publication. Kosciolek says she has made it a practice to wash her hands before going to the buffet, and then washing them again before she eats, since buffet implements aren’t sanitized after each passenger touches them. In February 2023, for instance, a school of K-8 students in Livonia, Michigan shut down as over 115 students and staff members contracted this virus, according to reports. If you are around a family member who is sick or taking care of someone wiping down surfaces that are shared can also help decrease transmission of this virus within a household. 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.
Symptoms typically last only 24 to 48 hours but keep up the good hygiene for longer; people may be contagious for as long as two weeks after recovery. First and foremost, wash your hands often with hot water and soap; the CDC recommends hitting the sink before and after eating and smoking, after touching your face, after using the restroom, and whenever your hands are dirty. Limit person-to-person contact as much as possible (we're not saying you absolutely must refuse the captain a handshake at his cocktail party ... just use your judgment throughout the cruise). Norovirus is named after an outbreak that occurred in Norwalk, Ohio, in the late 1960s. Because people of all ages can get sick with norovirus, it can spread easily and quickly.
What is Norovirus and how is it spread?
The UK Health Security Agency recently reported that norovirus cases are approximately 66% higher this season than the five-season average of the same period before COVID-19. While each virus has a different ability to transmit, norovirus is a highly transmissible infection. According to the CDC, each person who is infected with norovirus sheds billions of viral particles. Many of the symptoms last for just two or three days and while it may come on and leave quite quickly in comparison to other viruses, during the time the symptoms are present, it can be extremely uncomfortable. Norovirus is a viral infection that is one of the most common types of gastroenteritis — a condition that causes nausea, vomiting, diarrhea, and abdominal upset.
Outbreaks 2016 reports
Norovirus — a common and contagious virus that causes vomiting and diarrhea — is on the rise throughout the United States, especially on cruise ships. Norovirus cases aboard cruise ships have spiked for the first time in over 10 years, and experts believe more lenient travel restrictions and an increase in cruise passengers following the Covid pandemic are to blame. Shipboard medical service fees vary and are usually set by medical practitioners.
Norovirus Cases On Cruise Ships Skyrocket: Here’s Why—And How To Avoid Getting Sick
Royal Caribbean International's 'Oasis of the Seas' cruise ship is seen at Port Canaveral, Florida ... [+] on January 12, 2019, after returning a day early from a seven-night Caribbean cruise when over 400 passengers and crew members suffered gastrointestinal illness due to a suspected Norovirus outbreak. 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. "Health officials track illness on cruise ships. So outbreaks are found and reported more quickly on a cruise ship than on land," reads the CDC's facts page. The simple answer is that cruise ships are required to report cases of acute gastroenteritis to the CDC, even when the numbers are low.
It only takes a small number of virus particles for norovirus to spread, which is why norovirus causes so many explosive outbreaks, Ko previously told TODAY.com. 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. For the most part, Norovirus outbreaks are the results of passengers setting sail sick ... When on board, if you see someone with norovirus symptoms, you’re urged to leave the area and alert a crew member. Chiron says cruise lines try to keep ships clean and limit some interactions.
During this investigation, VSP used surveillance data and environmental and spatial analyses to improve field responses and quickly identify sources of norovirus exposure and transmission. Public health response to maritime AGE outbreaks involves robust and timely monitoring of AGE cases and collaborations with cruise companies. Cruise companies are encouraged to conduct frequent norovirus trainings for crew members, especially those with limited experience working with the cruise company (e.g., those who have served fewer than three contract terms). 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).
The total number of infected was 2385 (of those 2249 passengers and 136 crew). In 2014, the number of reported illness outbreaks on cruise ships was 17. The total number of infected was 3559 (of those 3354 passengers and 205 crew).
These symptoms usually appear between one to two days after contracting the virus but can appear as early as 12 hours after exposure. Cases typically last between 24 and 48 hours, though the illness may be more severe in young children and older adults, according to the Arizona Department of Health Services. Severe cases usually involve dehydration due to loss fluid—death is rarely ever a result.
Failing to comply with the crew's orders results in fines or even discharge from the ship. 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. 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. Your travel insurance will not cover cancellations due to the fear of illness, but it will cover you if you cancel because you got sick before you went or are stricken onboard.
Zika symptoms are fever, skin rash, pain in joints, conjunctivitis (pink eye). An "illness outbreak" is considered when 3% or more of all passengers report symptoms to the ship's med staff. In such cases, the CDC requires cruise lines to file a medical report. That means data for norovirus on cruise ships is more readily available than for other entities.
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. Therefore, the CDC has reports from every cruise vessel, on just about every cruise, even if there was no illness. If at any time during the cruise the number of ill passengers or crew exceeds 2 percent, the vessel must file a special report notifying CDC of the illness.
