The 4 most common contagious diseases on a cruise ship Québec Blue Cross

viruses on cruise ships

Cruise ships publish daily health and safety instructions to their passengers on how to avoid mosquito bites. Zika symptoms are fever, skin rash, pain in joints, conjunctivitis (pink eye). 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. 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.

Facts About Noroviruses on Cruise Ships

It’s the most number of reported norovirus outbreaks on cruise ships since 2012, when there were 16. 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). There have currently been 13 norovirus outbreaks on cruise ships in 2023. The most recent outbreak occurred on a Viking Cruises ship, which traveled from Iceland and docked in New York City. About 13% of its passengers and several crew members became ill with the virus while on board.

What is norovirus and how do you treat it? What to know about the ‘cruise ship virus’

If anyone brings about the virus, it could readily spread rapidly. Norovirus is highly infectious, as I’ve described for Forbes previously. 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. In 2012, the number of reported illness outbreaks on cruise ships was 34. The total number of infected was 5542 (of those 5079 passengers and 463 crew). In 2013, the number of reported illness outbreaks on cruise ships was 22.

Best Covid-19 Travel Insurance Plans

One day after the C.D.C. announcement, as dozens of crew members and other passengers were confined to small cabins, infected and quarantined, thousands of revelers packed into ship bars, casinos and deck venues, partying like it was 2019. The Centers for Disease Control and Prevention is monitoring or investigating 94 ships for COVID-19 as of Monday, as it warns Americans to "avoid cruise travel" regardless of vaccination status. 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.

You can also get a low-grade fever, chills, a headache, and muscle aches. Such symptoms tend to emerge rather suddenly about one or two days after the virus has gone down your pie hole. 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. When a single case of norovirus appears on a cruise ship, it can quickly become an outbreak affecting hundreds or even thousands of people.

Here are listed latest cruise ship Norovirus outbreaks on passenger ships, with information what is and how to avoid Norovirus on cruise ships, CDC reports, and news updates. Passengers who experience norovirus symptoms like vomiting and diarrhea should notify staff and follow recommended precautions, per the CDC. Outbreaks of the stomach bug have surged on cruise ships this year, reaching the highest levels seen in 10 years. Since January 2023, there have been 13 confirmed norovirus outbreaks on cruise ships under U.S. jurisdiction — that's more outbreaks in six months than there have been during any full year since 2012, according to data from the U.S. CruiseMapper's Norovirus survey is based on official data from CDC.gov (USA's "Centers for Disease Control and Prevention").

Most hospital ships are navy vessels (operated by military forces) which are specifically built for use in war zones. The most severe outbreaks were reported in Brazil, with an alarming surge in newborns with microcephaly. If the mother is infected, the virus may cause microcephaly in newborns. This is a neurodevelopmental disorder - babies are born with an underdeveloped head. Zika virus (aka ZIKV) is a Flavivirus - from the genus of the viruses named West Nile, dengue, tick-borne encephalitis, yellow fever. These plus several other viruses may cause encephalitis (acute brain inflammation).

The Looming Marburg Crisis: How Virus Outbreaks Escalate and Spread

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 their cabins. 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. One day after the C.D.C. advised against all travel on cruise ships, thousands of cruisers partied like it was 2019. But worries about onboard policies — and frustration over quarantines — are rising.

Public Health Service Act; its mission is to prevent the introduction and spread of communicable diseases in the U.S. More specifically, it runs the Vessel Sanitation Program, which monitors illness outbreaks on ships carrying more than 13 passengers. Green status means there have been no reported cases of coronavirus or COVID-19-like illnesses on board.

An "illness outbreak" is considered when 3% or more of all passengers report symptoms to the ship's med staff. In such cases, the CDC requires cruise lines to file a medical report. If an unvaccinated or under-vaccinated passenger or crew member contracts the virus and brings it on board, other vulnerable people can get sick, Chen explains. (A ship was quarantined off the coast of St. Lucia in 2019 when measles was reported on board.) The same goes for chicken pox (varicella), which is similarly caused by a highly contagious virus that can circulate among unvaccinated people. The “vomiting” should be a tip off as to what may happen when you get infected with norovirus. The most common symptoms of a norovirus infection are nausea, vomiting, diarrhea, and stomach cramping.

The total number of infected was 2385 (of those 2249 passengers and 136 crew). In 2014, the number of reported illness outbreaks on cruise ships was 17. 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).

The virus most often spreads in closed and crowded environments, such as hospitals, nursing homes, child care centers, school and cruise ships, according to the Mayo Clinic. In late February, more than 300 people aboard a Princess Cruises ship fell ill with diarrhea and vomiting, according to the CDC, though the agency didn’t cite the cause of the illness that sickened the 284 passengers and 34 crew. The Ruby Princess increased disinfection and cleaning procedures in the wake of the outbreak.

The recent surge in Norovirus outbreaks underscores the necessity of vigilance and proper understanding of this issue, both for those planning a dream vacation at sea and for those in the cruise industry itself. Together, we can work towards ensuring that cruise ships remain a place of relaxation and enjoyment, rather than a breeding ground for this troublesome virus. Shipboard hospitals as facilities and equipment vary by cruise line and vessel. Clinic's size usually depends on the ship's capacity (passengers plus crew). Generally, bigger and newer ships offer larger and better-equipped medical facilities and are served by bigger infirmary staff.

Though people often call it the “stomach flu,” it has nothing to do with flu, Brian Labus, PhD, MPH, REHS, an expert in infectious diseases, told Health. Norovirus is a highly contagious virus often described as a “stomach bug,” the generic description of the leading cause of nausea, diarrhea, stomach pain and vomiting in the U.S., according to the Centers for Disease Control and Prevention. If seasickness symptoms are accompanied by diarrhea or fever, passengers should immediately seek medical treatment for Norovirus and avoid spreading the illness to others.
