Because norovirus can linger on surfaces and resists many common disinfectants, it can result in outbreaks on back-to-back cruises. Still, the agency says that norovirus on cruise ships only account for 1 percent of reported outbreaks of the illness and notes that “acute gastrointestinal illness is relatively infrequent” on ships. ☐ Avoid contact with people who are ill. ☐ Follow safe food and water precautions when eating off ship at ports of call. ☐ Maintain good fluid intake and avoid excessive alcohol consumption.
Nearly 30 Silverseas cruise passengers fall ill with diarrhea at sea
Coronavirus hospitalizations in the state have also risen from about 1,200 patients two weeks ago to about 3,400 on Wednesday. But that is still less than one-fifth the number of hospitalizations reported in late August due to the delta wave. Around 15 passengers aboard the Norwegian Dawn remain in isolation because of an undisclosed "health risk" and are undergoing testing, according to the Mauritius Ports Authority. The crew serves with short-term (2 weeks to 2 years) and long-term (min 2 years) contracts. Volunteer crew members occupy both medical (surgeons, dentists, nurses) and general jobs (deckhands, seamen, engineers, machinists, electricians, teachers, cooks, welders, plumbers, agriculturalists.

When booking a cruise, travelers should check the trip cancellation policies and consider purchasing trip cancellation insurance (see Sec. 6, Ch. 1, Travel Insurance, Travel Health Insurance & Medical Evacuation Insurance). 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 following statistics show the number of cruise ship illness outbreaks in recent years.
Cruise Ship Illness: How to Protect Yourself
And while interest in cruising is down slightly among the 50-plus population this year compared to last, a recent AAA survey finds that, overall, the share of travelers considering a cruise vacation in 2023 is up. Lastly, “if you see someone sick like vomiting or having diarrhea, remove yourself from the area and notify cruise staff if they are not already aware,” Boden-Albala says. So the decision to travel or not should depend on several factors, Ungerleider says, including your personal health status and risk tolerance. 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.

Infectious Disease Health Risks
“It’s just really the perfect scenario for transmission of highly contagious GI [gastrointestinal] pathogens,” Lucar says. Medical center visits are primarily the result of acute illness or injury. The most frequently reported diagnoses include respiratory illnesses (30%–40%); injuries from slips, trips, or falls (12%–18%); seasickness (10%); and gastrointestinal (GI) illness (10%); 80% of onboard deaths are due to cardiovascular events. The cause of the outbreak — which has impacted roughly 5% of the ship’s passenger population — is still unknown, but the CDC notes that norovirus outbreaks are primarily caused by eating contaminated food or drinking contaminated water.
In the past 10 years, only three other cruise ships have received sanitation scores below 70, CDC records show. Violations can include something as small as not posting a raw-eggs advisory on the omelet station or a single fly hovering in a food area. But before going on your next cruise adventure, it doesn't hurt to check out the ship's most recent sanitation rating. As 95 of the world's top 100 largest megapolises are port cities, "hospital ships" could provide healthcare very quickly and more efficiently to large numbers of people. Some cruise lines offer hand-sanitizer dispensers near the ship's restaurants, Lido/pool deck areas and other more crowded public spaces in their effort to keep a lid on sickness outbreaks. The symptoms are nausea, vomiting, diarrhea, indigestion, abdominal cramps.
Noninfectious Health Risks
For guidance on how to avoid bites from mosquitoes and other disease-transmitting arthropod vectors, both onboard and while on shore at ports of call, see Sec. 4, Ch. For specific details on yellow fever vaccination and malaria prevention, see Sec. 2, Ch. 5, Yellow Fever Vaccine & Malaria Prevention Information, by Country. The Centers for Disease Control and Prevention said 28 of Silver Nova’s 633 guests reported being ill during a voyage that began on March 31, along with one of the vessel’s crew members. The reported cases are totals for the entire voyage and do not represent how many people are actively sick at any one time, the CDC said.
Norovirus outbreaks 2023 reports
Make an appointment with your healthcare provider or a travel health specialist that takes place at least one month before you leave. They can help you get destination-specific vaccines, medicines, and information. Discussing your health concerns, itinerary, and planned activities with your provider allows them to give more specific advice and recommendations.
After Travel
Outbreaks on ships can be sustained over multiple voyages by crewmembers who remain onboard, or by persistent environmental contamination. Port visits can expose travelers to local diseases and, conversely, be a conduit for disease introduction into shoreside communities. To quell the spread of the stomach bug, Silversea Cruises reportedly quarantined its impacted passengers and crew member and “increased cleaning and disinfection procedures,” the CDC said. 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.
The illness lasts 1 to 4 days, but some people (especially elderly) may be contagious for up to 2 weeks after recovery. 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. In response to the outbreak, the crew of the Queen Victoria have “increased cleaning and disinfection procedures” and have “isolated ill passengers and crew,” the C.D.C. said.
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). The spray is chemical-free, odourless, transparent and can be applied to all surfaces. By taking steps to protect yourself from illness, you minimize your risk of getting sick on a cruise vacation and you can enjoy every moment of your oceangoing getaway. If you do get sick, seek medical attention, particularly for severe symptoms that may indicate a more serious ailment.
Improvements in ship design and standardization of water disinfection have reduced the risk for Legionella growth and colonization. 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.
Check CDC’s webpage for your destination to see what vaccines or medicines you may need and what diseases or health risks are a concern at your destination. Most cruise lines have policies that do not permit people to board after their 24th week of pregnancy. Contact cruise lines directly for specific guidance before booking. For additional information on preparing pregnant people for international travel, see Sec. 7, Ch.

And the CDC did not say it would adopt any changes, adding it still had plans to allow for the expiration of a set of rules that cruises must follow to sail during the pandemic. The regulation, called a conditional sailing order, is scheduled to expire on Jan. 15 to become a voluntary program. The Queen Victoria, operated by Cunard Cruise Line, departed San Francisco Wednesday on its way from Florida to Hawaii. The CDC reported that the cause of the illness and how it spread remains unknown.
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. Severe cases usually involve dehydration due to loss fluid—death is rarely ever a result.
“You must be diligent beyond your common understanding of when to wash your hands, because there are millions of norovirus particles spreading in various areas,” Boden-Albala says. According to the CDC, the incubation period for norovirus — the time it takes between infection and the onset of symptoms — is between 12 and 48 hours. The outbreak was reported one day before the “Easter” themed cruise was scheduled to end. “The health and safety of our guests, crew, and the communities we visit are our top priority,” a spokesperson for Silversea Cruises told The Post in a statement.
