With cruise ship "outbreaks" regularly appearing in the news, awareness of Norovirus - an extremely common and highly contagious virus that causes gastroenteritis - has been significantly raised.
But before you reconsider that long-awaited cruise vacation because of gloom-and-doom reports on television and in your daily paper, know these facts:
Norovirus is not a "cruise ship" virus, nor does it limit itself to sea-going vessels.
Norovirus spreads swiftly wherever there are many people in a small area, including nursing homes, restaurants, hotels, dormitories ... and cruise ships.
The common cold is the only illness more common, and the Centers for Disease Control and Prevention in Atlanta estimates that there are more than 20 million cases of Norovirus annually.
Norovirus is associated with cruise travel simply because health officials are required to track illnesses on ships (and are not at hotels and resorts); therefore, outbreaks are found and reported more quickly at sea than on land.
What are the symptoms? What are the cruise lines doing to combat germs? In the following Q&A, we tell you everything you need to know about Norovirus - and how to avoid getting sick on your next cruise vacation.
Question: What is Norovirus and how is it spread?
Answer: Norovirus is named after an outbreak that occurred in Norwalk, Ohio, some 35 years ago. According to the Centers for Disease Control and Prevention's Vessel Sanitation Program, "Noroviruses are a group of viruses (previously known as Norwalk-like viruses) that can affect the stomach and intestines. These viruses can cause people to have gastroenteritis, an inflammation of the stomach and the large intestines. Gastroenteritis is sometimes called a calicivirus infection or food poisoning, even though it may not always be related to food."
Though Norovirus can be passed via contaminated food and water, when it comes to cruise ships it is typically spread through physical contact with ill people or surfaces/objects they may have touched. This includes shaking hands, caring for a sick friend or family member, sharing food or eating from the same utensils, and not washing hands after using the bathroom or changing diapers (the highly transmittable fecal-oral spread).
Bottom line? For the most part, Norovirus outbreaks are the results of guests setting sail sick ... and passing it around.
Q: What are the symptoms?
A: Though generally moderate, symptoms are often flu-like (in fact, Norovirus is often called the "stomach flu, " even though it is not related to influenza). Symptoms include nausea, vomiting, diarrhea and abdominal cramps; children often vomit more than adults. A low-grade fever and headache are also possible.
Q: What preventative measures should I take to avoid coming down with Norovirus?
A: 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).
Cruise Critic members advise packing extra soap, a supply of Lysol and a bottle of Pepto-Bismol (just in case).
Beyond that, avoid uncooked food as much as possible. Stick to bottled water, and don't share drinking glasses and eating utensils.
Q: What happens if I come down with Norovirus while on a cruise ship?
A: Beyond a visit to the ship's doctor, be sure to drink plenty of water as dehydration is a common side-effect. If they report symptoms, passengers are typically quarantined to their cabins to prevent spreading the illness to others - not an ideal situation, but necessary.
Q: How long will it take me to recover?
A: Once you have been exposed to Norovirus, it takes anywhere from one to three days for its symptoms to appear; symptoms typically last only 24 to 48 hours but keep up the good hygiene - people may be contagious for as long as two weeks after recovery.
Q: Why do I only hear about Norovirus outbreaks on cruise ships?
A: It has been a particular problem of late for cruise ships because passengers and crew typically occupy close - and closed-in - quarters, such as casinos, theaters and banquet-style dining rooms. However, Norovirus has been known to close schools, attack college dormitories and even infect a Hollywood Academy Awards party.
According to a spokesman at the CDC, "the reason you hear about Norovirus on cruise ships is because they are required to report every incidence of gastrointestinal illness. Nowhere else in the public health system of the United States is Norovirus a reportable illness. Norovirus is not a 'cruise ship' illness, but an illness commonly seen in many settings throughout the United States."
Q: What do cruise lines do to halt the spread of Norovirus?
A: Typically, when there's a significant outbreak of Norovirus or a similar illness (the CDC requires cruise lines to immediately file a report when more than 2 percent of passengers report symptoms), crewmembers clean even more thoroughly than usual - with stronger solvents. Buffet service often switches from "help yourself" to manned stations. You may see salt and pepper shakers disappear from tables. Beyond that, crewmembers distribute information to passengers onboard offering precautionary tips, as well as a heads-up memo at embarkation to travelers boarding a ship that had previously seen a high percentage of illness. And, as mentioned above, passengers who report symptoms may be quarantined to the their cabins.
There are also behind-the-scenes procedures that cruise lines must follow. For instance, medical officers are required to maintain illness incident counts for each voyage that involves a stop at an American port. They are also required to communicate to the CDC, within 24-hours of arrival at a U.S. port, "the number of passengers and crew members who reported diarrhea to the ship's medical staff" during that voyage.
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. These enhanced cleanings are generally coordinated with the CDC.future technologies around the world future behind the scenes future beyond imagination future off dat future on forsyth opposite of future proof future up future with covid future with dreads meteorology application futurology bedeutung futurology is the study of futurology ologies future mask off future soldier future from 8 mile now future outcomes futurology vocabulary future boy conan future husband future business leaders of america future and ciara future automation future chevrolet future days future kimonos future radar future songs future scholar except future tense form future for us future into meaning into future synonym near future report future over my head futurology and education futurology class futurology english futurology of education pdf futurology youtube channels future diary future gohan future kimonos future sight future the rapper future kings around the world future didn't even know it future break even future inside future scala next future of epl opposite of future date future past meaning future generali since until future notice future continuous until futurology books futurology english futurology of education pdf future atlanta future concert future generations future and drake future marvel movies future nails future of cryptocurrency future quiz future x wife strain future youtube future younger future zone future before future by billie eilish fridays for future contra kommentar future tense of despite even future future from 8 mile in real life into future treasures future near future of next plc future off white nike releases until future perfect future vs conditional spanish image future (via google) g.co/helppay futurology kiosk recklinghausen futurology nədir futurology private futurology synonyms future goten future jobs in demand future kind future lori harvey future ryder cup sites future utility run star hike future youtube future as jesus future war between india and china future near opposite of future state future past review duran duran future versus battle future vs conditional spanish the future within our grasp xenoblade futurology history definition futurology meaning in hindi futurology of education ppt futurology origin books about futurology future children future diary characters future earth future beyond meat future beyond 5g future of next future outta time future continuous until antonyms futurology futurology la gi futurology lyrics futurology uk future endings spanish future ford roseville future inflation calculator future meaning future nissan future progressive tense future after that lyrics future of work during covid 19 future from eminem future of front end development 2020 corning future made of glass video future on computer meme future without his glasses futurology studies limited futurology que es future jesus future quotes rapper funny future xbox games future for frontliners requirements future islands outside lands future with money future atlanta future james bond future memes future ready future without glasses future after that future around the world future tense even if great future in front of you future out the mud future past duran duran lyrics future pro baseball futurology en español futurology nghia la gi futurology report futurology techniques futurology in art future ford future business leaders of america future tense spanish future x men movies future young thug future about irctc share future before i tell a lie future on his phone wait till future is done futurology definition futurology meaning in hindi futurology in education pdf futurology online course futurology review antonyms for futurology
