Virus outbreaks on cruise ships are actually not that uncommon. Such viral/bacterial outbreak incidents affect the vacation experience of thousands of people, being packed up in a floating resort for many days on end. 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. 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. The hotel staff is required to implement special cleaning and disinfection procedures for sanitizing the whole ship.

The spray is chemical-free, odourless, transparent and can be applied to all surfaces. The RT-aPCR test is not commonly done because of the short course of the infection. It may be used if there is a large public outbreak or if a person has a weakened immune system (e.g., due to leukemia or organ transplant).
Cruise Ship Norovirus Outbreaks
Costa Cruises has canceled departures on four of its ships with sailing dates from Jan. 25 to Feb. 2, according to Express UK and Cruise Fever. Trips on the Costa Serena, the Costa Atlantica, the Costa Venezia and the Costa neoRomantica have all been canceled and the ships are all currently docked in ornear China, according to CruiseMapper.com. MSC Cruises has also announced the cancellation of its Tuesday trip from Shanghai on its MSC Splendida ship, according to Cruise Industry News and Express UK.
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. 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). This leads you to have stomach pain, nausea, and diarrhea and to throw up. Norovirus is a contagious virus that causes vomiting and diarrhea.

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. Cruise lines should warn their pregnant passengers of the virus. Cruise ships publish daily health and safety instructions to their passengers on how to avoid mosquito bites.

Both emergency and basic care are available on the ship 24 hours a day. Seasickness is physical disorientation as a result of conflicting signals received by the brain from different body senses. Our inner ear senses the ship's irregular motion, which our eyes can't see because the floor and walls are stable. Depending on individual balance, our ability to adjust to motions varies, so not everyone experiences seasickness.
How is norovirus spread?
Less commonly, a test called the real-time reverse transcription-polymerase chain reaction (RT-qPCR) test may be used to diagnose norovirus. This assay detects the genetic material (RNA) of the virus and can be performed on stool, vomitus, food, water, and environmental specimens. During a medical history, your healthcare provider will inquire about your specific symptoms, especially with regard to those related to dehydration.

Passengers scheduled to sail on the cruise ship will receive full refunds for the cancellation. The key treatment for the norovirus is to drink lots of fluids. Your healthcare provider may also inquire about the specifics of your diarrhea, like whether it is watery versus bloody, or whether you have experienced a high fever. Answers to these questions can help sway your healthcare provider away or toward a diagnosis of norovirus. Lastly, sharing food or eating utensils with someone who is infected with the norovirus may spread the infection, as can touching objects that contain norovirus particles and then touching your mouth, nose, and/or eyes. Severe dehydration may require medical treatment such as IV fluids or medications to help stop the vomiting.
Royal Caribbean is suspending Monday's scheduled sailing of one of its cruise ships out of the country due to the deadly virus. Norovirus is considered a foodborne illness because the virus can easily contaminate food and water sources. In fact, the majority of norovirus outbreaks occur in restaurants where an infected preparer or server handles food or serving items with their bare hands. There are no internationally specified regulations governing ship infirmaries and medical staffing.
There are more than 21 million US cases reported annually, of which 1 mill related to kids. Outbreaks happen mostly during winter months and mainly in more crowded places with close quarters. Among those are schools, hospitals, nursing homes, dormitories, prisons, big resorts, bigger passenger ships (including cruise ferries). Norovirus is often branded as "cruise ship virus" simply because on ships health officials are required to report every gastrointestinal illness incident. This means Norovirus outbreaks are reported more quickly on ships than on land. Just for comparison, the virus can afflict as many as 3000 people per day in only one big city, which is about the passenger capacity of a typical modern cruiser.
To do that, they use stronger solvents, like Microbac, chlorine bleach, hydrogen peroxide. The Lido Deck's bistro/buffet service switches to manned stations. Sick passengers and crew are quarantined in their rooms, typically for at least 2 days.
As to its efficiency - a mere 20 particles are enough to get you. Be sure to carefully wash fruits and vegetables before preparing and eating them. Oysters and shellfish need to be thoroughly cooked before they are ready for consumption.
