Controlling Contagious Infections

Apr 28th 09

It never fails; one crewmember comes down with the sniffles and within two weeks, the entire crew is in various stages of getting the bug or getting over it. Now that the ominous Swine Flu Virus is dominating international headlines, government authorities in the U.S. and European Union have issued travel advisories against visiting Mexico for nonessential reasons and the World Health Organization (WHO) is talking about the threat of a global pandemic – it’s a good time for yacht crew to consider some practical, common sense steps to help prevent infection from spreading on board.

The following tips include suggestions from the Centers for Disease Control and Prevention (CDC) and the American Red Cross.


  • -Wash your hands thoroughly and often.
  • -When you sneeze or cough, do not cover your face with your hands, but rather try to cover your nose and mouth with a tissue or bury them in the crook of your arm, which does not typically come into contact with other surfaces the way your hands do.
  • -Make sure that used tissues are placed in a garbage can.
  • -Use latex gloves when handling the personal hygiene items of others during cleaning.
  • -Always use latex gloves when handling trash.
  • -If hand-washing dishes, be sure to use antibacterial soap and a sanitizing rinse (one tablespoon bleach per gallon of water).
  • -Avoid touching your eyes, nose and mouth, especially when you have been exposed to a sick individual.
  • -Get flu shots and stay current on your vaccinations.
  • -Request a supply of antiviral medications (Tamiflu or Relenza) for the vessel med kit. Administer as directed to a crewmember or guest at the onset of a viral infection.
  • -Have a sufficient supply of disinfectants like bleach, disinfecting spray, antibacterial soap and hand sanitizer on board.

  • -If a crewmember is obviously sick, do not require that they try to “work through it.” It's better for the rest of the crew to pick up the slack than to risk having the entire crew becoming ill.
  • -Try to isolate a sick crewmember. If he or she shares a cabin, their cabin mate should be allowed to use other accommodations.
  • -Limit a sick crewmember’s exposure to the rest of the crew and guests.
  • -It's not unreasonable for the caregiver to wear a simple protective mask and gloves when tending to someone who is sick, especially if coughing, sneezing or vomiting are symptoms.
  • -Once a crewmember has recovered, their bedding should be washed with bleach and the room should be thoroughly cleaned and disinfected.

  • -A single crewmember should monitor and care for a sick person in order to limit his or her exposure to others. This way, the sickness also can be accurately observed in terms of how it is progressing.
  • -Most viral infections do not require medical care and will run their course on their own.
  • -Symptoms that are considered “typical” of a viral infection include fatigue, body aches, chills, fever, vomiting, diarrhea, loss of appetite, runny nose and coughing. These symptoms do not normally require specialized care for an otherwise healthy individual.
  • -However, there are clear signs that a sick person will need medical support; these signs include:

    -The inability to consume or keep down liquids for a period of more than 48 hours.

    -Loss of elasticity in the skin, sunken eyes and/or an inability to produce tears.

    -A fever over 102 degrees F, which does not go down after taking an analgesic.

    -Loss of consciousness/ inability to wake.

    -A severe headache with neck stiffness.

    -Difficulty breathing.


    -Blood present in vomit or diarrhea.


Swine Flu

Because of the contagious nature of the illness, which had killed more than 150 people in Mexico as of April 28, the WHO has raised its global alert level to phase 4 from phase 3 (phase 6 is a pandemic). Both the CDC and WHO continue to recommended treatment for victims of viral infections following the guidelines above.

    "...pandemic but does not necessarily mean that a pandemic is a forgone conclusion.

    Phase 5 is characterized by human-to-human spread of the virus into at least two countries in one WHO region. While most countries will not be affected at this stage, the declaration of Phase 5 is a strong signal that a pandemic is imminent and that the time to finalize the organization, communication, and implementation of the planned mitigation measures is short.

    Phase 6, the pandemic phase, is characterized by community level outbreaks in at least one other country in a different WHO region in addition to the criteria defined in Phase 5. Designation of this phase will indicate that a global pandemic is under way."

  • As of April 29th the WHO has raised the "pandemic alert level" to 5. Since the scale only goes to 6 it is certainly concerning. However, in refering to the WHO website, it becomes clear that even a level 5 alert is no cause for widespread panic but rather a call for reasonable preparation and consideration.

    "In nature, influenza viruses circulate continuously among animals, especially birds. Even though such viruses might theoretically develop into pandemic viruses, in Phase 1 no viruses circulating among animals have been reported to cause infections in humans.

    In Phase 2 an animal influenza virus circulating among domesticated or wild animals is known to have caused infection in humans, and is therefore considered a potential pandemic threat.

    In Phase 3, an animal or human-animal influenza reassortant virus has caused sporadic cases or small clusters of disease in people, but has not resulted in human-to-human transmission sufficient to sustain community-level outbreaks. Limited human-to-human transmission may occur under some circumstances, for example, when there is close contact between an infected person and an unprotected caregiver. However, limited transmission under such restricted circumstances does not indicate that the virus has gained the level of transmissibility among humans necessary to cause a pandemic.

    Phase 4 is characterized by verified human-to-human transmission of an animal or human-animal influenza reassortant virus able to cause “community-level outbreaks.” The ability to cause sustained disease outbreaks in a community marks a significant upwards shift in the risk for a pandemic. Any country that suspects or has verified such an event should urgently consult with WHO so that the situation can be jointly assessed and a decision made by the affected country if implementation of a rapid pandemic containment operation is warranted. Phase 4 indicates a significant increase in risk of a pandemic but does not necessari
