Royal Caribbean Group's eradication program is certainly a positive step, but if you're still worried about catching norovirus, the risks are low. It is worth noting the CDC outbreaks page does list Celebrity Constellation as having an outbreak in January 2024. In June 2023, Royal Caribbean launched a norovirus eradication campaign that included a range of new protocols and policies. Surfaces or objects that are contaminated with norovirus can be cleaned with a high-level disinfectant like bleach, per Ostrosky.

Norovirus outbreaks 2022 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. 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.
Norovirus outbreaks surging on cruise ships this year
The exact cause for the increase in the number of norovirus cases is not clear, but the increasing demand for cruises could be one explanation for the rise in reported cases, said Labus. Studies have shown that norovirus can continue to spread for two weeks or more after an infected person stops having symptoms of the illness, according to the CDC. According to the CDC, norovirus is the leading cause of vomiting, diarrhea, and foodborne illness in the United States. The Vessel Sanitation Program monitors vessel cleanliness, and there is no correlation between scores received and outbreaks of gastrointestinal illness. The twice-yearly exam is notoriously thorough and challenging, with scores of 85 or below considered failing.

It takes about 30 sec of hard rubbing with hot water and soap (including under the nails) to wash it. During the onboard illness outbreak, VSP requires the cruise company to activate the "Outbreak Prevention and Response Plan" (vessel's response to illness cases). Norovirus outbreaks also frequently occur in schools, childcare centers, colleges, and universities. Norovirus outbreaks on school and university campuses have even led to campus closures.
What is Norovirus and how is it spread?
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 bug thrives in crowded conditions and is spread through food and by touching contaminated surfaces. The easiest way to avoid the ailment is to wash your hands with soap and water after using the bathroom, before eating and after touching surfaces touched by others. While cruise ships have strict sanitation practices, the resilience of norovirus complicates matters. The virus can survive for days on surfaces and is resistant to many common disinfectants, making it challenging to eliminate once an outbreak has occurred.
Cruise ship hospital (medical care)
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. VSP (abbrev "Vessel Sanitation Program") monitors CDC's observations on illness patterns for GI (gastrointestinal) outbreaks on passenger shipping vessels (ferries and cruise ships). Find out why norovirus is unfairly labeled a cruise ship illness, what cruise lines do to minimize onboard spread and whether you should be worried about it on your next voyage. An excessive number of news reports exist for norovirus cases on ships, making it seem to the unsuspecting public that cruise vessels are dirty or you're likely to get sick if you sail.
The virus is not seasonal and usually not serious (in medical terms). 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. You can get norovirus from an infected person, from contaminated food or water, or by touching contaminated surfaces. The virus causes your stomach or intestines or both to get inflamed (acute gastroenteritis).

Norovirus outbreaks 2023 reports
All cruise ships participate in the CDC's Vessel Sanitation Program, which has been in place since the 1970s to conduct random, unannounced inspections of ships if they wish to visit a port in the United States. Another big step Royal Caribbean Group made in improving the health of guests and crew members on its ships was to invest more in its public health inspection program. According to the Centers for Disease Control and Prevention, there are 19 to 21 million cases of vomiting and diarrhea illnesses caused by norovirus each year.
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. 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 infects between 19 million and 21 million Americans annually, the CDC reports. 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. They are located on upper decks and include cabins for families, couples and single cabins.
Plus, hand sanitizer and cleaning materials that don’t contain something more powerful like bleach may not get rid of the virus from a surface. Norovirus cases aboard cruise ships were on a steady decline between 2006 and 2019, according to CDC data. When the Covid pandemic hit, the CDC made a travel health notice advising against cruise ship travel. Because of this, there were no norovirus outbreaks in 2020 and 2021. However, in March 2022 the agency dropped the health notice, though it strongly urged against cruising without a booster shot.
The total number of infected was 3559 (of those 3354 passengers and 205 crew). In 2015, the number of reported illness outbreaks on cruise ships was 23. The total number of infected was 2570 (of those 2458 passengers and 112 crew). In 2016, the number of reported illness outbreaks on cruise ships was 23. The total number of infected was 2504 (of those 2378 passengers and 126 crew).
In the vast majority of people, norovirus symptoms will last several days and resolve on their own. Norovirus can spread year-round, but it tends to have a wintertime seasonality and peak during the colder months. Outbreaks are most common between November and April, TODAY.com previously reported. The crew serves with short-term (2 weeks to 2 years) and long-term (min 2 years) contracts.
According to the Cruise Lines Industry Association, the risk each year of getting laboratory-confirmed norovirus during a ship outbreak is about 1 in 5,500. Over half of all cases originate in long-term health care facilities, according to the CDC, while less than 1 percent of all norovirus cases come from cruise ships. The CDC regularly inspects cruise ships and monitors the number of outbreaks.
No one wants to get sick, especially on vacation, and Royal Caribbean implemented a program in 2023 that got rid of one of the worst illnesses people sometimes catch 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. However, unlike on land, most basic travel insurance policies don't cover medical treatments on cruise ships as they are not from the patient's primary caregiver. Purchasing cruise travel insurance with health coverage (medical clauses) is highly recommended. 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.
