Crew member transmission was followed by passenger transmission on voyages 3, 4, and 5. Approximately 70% of crew members with AGE interacted with passengers (i.e., housekeeping and food and beverage services). VSP partnered with the United States Agency for Toxic Substances and Disease Registry’s Geospatial Research, Analysis, and Services Program to create four-dimensional visual models of the ship. These models helped visualize continued norovirus transmission and sources of potential exposure (e.g., contaminated surfaces in cabins of persons with AGE and high-touch surfaces in common areas).
The Worst Norovirus Outbreak On A Cruise Ship
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. Norovirus can also get into food before, during or after preparation, and it's the top germ causing foodborne illness in the U.S., per the CDC. Virus particles can contaminate drinking water that isn't treated properly or pools when people poop in the water.
What is Norovirus and how is it spread?
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. 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).

Most hospital ships are navy vessels (operated by military forces) which are specifically built for use in war zones. Hospital ships are designated as floating medical facilities (hospitals). Generally, Zika is a mosquito-borne virus spread by Aedes aegypti (aka "yellow fever mosquito") and Aedes albopictus (aka "Asian tiger mosquito"). However, it became "cruise virus" since the decease can also result from intrauterine (contraceptive device), sexual intercourse, blood transfusion, lab exposure, organ/tissue transplantation, breast milk transmission. She has worked in the cruise industry since 2015 and has taken over 30 cruises. Now, she helps over 1 million people per month to plan their perfect cruise holidays.
After years of decline, norovirus outbreaks surge on cruise ships - CNN
After years of decline, norovirus outbreaks surge on cruise ships.

These are the cruise ships with the best — and worst — sanitation scores so far this year
Often labeled a "stomach bug," norovirus is the most common cause of nausea, vomiting, diarrhea and stomach pain, according to the CDC. That’s how many people have been infected with the norovirus while aboard cruise ships this year, according to CDC data. The outbreaks happened on Celebrity Cruises, Viking Cruises, Princess Cruises, Royal Caribbean International and P&O Cruises.
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. It's a very common, highly contagious, ruthlessly efficient and uncomfortably bad virus affecting the stomach and large intestines. Often called "stomach flu" (the med term is "Gastroenteritis") the infection results in massive vomiting and diarrhea. Sickness outbreaks are considered as such if the percentage of infected people is over 3%. The virus is not seasonal and usually not serious (in medical terms).
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.
Why are acute gastrointestinal illnesses including noroviruses associated with cruise ships?
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. Ashley Peterson, a passenger on the ship, tweeted a photo of a Dec. 22 letter from the ship's captain apologizing for being unable to make stops in Aruba and Bonaire. The letter said passengers would get $100 per room in onboard credit, as well refunds for planned excursions.
CDC ship illness outbreak investigations
But when it comes to the health of those travelers, it's not always smooth sailing. But for elderly people or those who suffer from chronic illnesses, Leshem says norovirus can cause severe disease, which may occasionally result in hospitalization and even death. He would advise such travelers to follow up to make sure the ship has followed the CDC’s guidance and recommendations for outbreaks. Norovirus is highly contagious and can spread directly through sick people and contaminated surfaces, food, or drinks. Shipboard hospitals as facilities and equipment vary by cruise line and vessel.
It hits 1 in 5 people annually and is the cause of ~50% of all foodborne illness outbreaks in the USA and for ~90% of all non-bacterial gastroenteritis worldwide. According to data from the CDC's Vessel Sanitation Program, the number of norovirus outbreaks on cruise ships docking at U.S. ports had years of steady decline after 2015. Overall rates of acute gastroenteritis on cruise ships in the U.S. also decreased from 2006 to 2019. Thirteen ships so far this year have reported outbreaks of the highly contagious stomach bug, the most since 2012, according to the U.S.

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

While current data suggests we are currently within the seasonal range, the CDC reports that this is an increase compared to the past years. Land-based operations ("Field Service") include mobile clinics providing screening for potential surgery patients, healthcare, dental care, also mental health programs, infrastructure projects. They are located on upper decks and include cabins for families, couples and single cabins. As of 2018, hospital ships have Brazil (6), China (5), Russia (6), USA (2), Spain (2), and India-Indonesia-Peru-Vietnam (x1).
People also are more likely to get sick now since pandemic restrictions have been lifted. For the past few years, people have not been exposed to as many common viruses and illnesses and now that exposure is rising, illnesses are bound to rise as well. “Infected people spread the virus widely and make it difficult for public health officials to contain the virus,” Boden-Albala said.
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 most recent norovirus outbreak was reported on the Viking Neptune cruise ship. During its June 6 to June 20 voyage, 110 of the ship’s 838 passengers, or 13.1 percent, were infected.
