Environmental Health and Prevention Services

Infectious Diarrhea

  • Outbreaks of nausea, stomach cramps, vomiting and diarrhea on cruise ships over the last decade have been linked to noroviruses, E-coli, or listed as “unknown.” While the number of cases of infectious diarrhea on cruise ships has fallen, frequent outbreaks continue. All passengers should practise good HANDWASHING. It is the most important thing that can be done to prevent infections.
  • When eating off the ship, remember:


  • Eat food that has been well-cooked and is still hot when served.
  • Avoid uncooked foods - especially shellfish and salads.
  • Avoid food from street vendors.
  • Drink purified or sealed bottled water when off the ship.
  • Wash your hands before eating or drinking.

Influenza & influenza-like illness

  • For high-risk travellers, consider an influenza shot before leaving.

Hepatitis A 

  • Hepatitis A is a viral infection of the liver that may cause nausea, fever, abdominal pain, loss of appetite and jaundice (yellowing of the skin and eyes). It is a potential risk to cruise travellers through contaminated food or water. The risk of hepatitis A being acquired onboard a ship is considered low; however, consider the land portion of travel to determine the full risk.
  • A single dose of hepatitis A vaccine provides up to 1 year of protection. A booster dose in 6-12 months provides protection for at least 20 years.
  • Indications for vaccination should be assessed individually as for any other trip or contact.

Insect protection

  • Many illnesses are spread through the bite of a mosquito. Travellers should use personal, protective measures on land-based tours in tropical and subtropical climates. For adults, a repellent with at least 30% DEET is suggested.
  • Limit exposure by wearing long-sleeved shirts, long pants, hat and boots while taking part in off-ship excursions.
  • When using sunscreen, apply the sunscreen first and allow it to dry for 3-5 minutes before applying the repellent.

Sun protection

  • While in the sun wear light-coloured, lightweight clothing that covers as much skin as possible (i.e. cottons and linens are good options).
  • Clothes should fit loosely for maximum comfort and to prevent chafing and heat rash.
  • Wear a hat with a wide rim for maximum coverage.
  • Wear sunscreen with a minimum SPF of 15 every day to prevent skin damage. Re-apply after swimming or activities that cause sweating.
  • Remember to apply sunscreen to ears and neck, and to use lip protection as well.
  • If possible stay indoors and out of the sun between 10 a.m. and 2 p.m. when the sun is the strongest.
  • Remember to wear sunglasses with UV protection; the sun can damage your eyes as well as your skin.

Skin protection 

  • Ideally, travellers should slowly get used to tropical climates, striving to keep the skin cool and clean through frequent showering. In humid climates it is important to dry off thoroughly; in dry climates use a moisturizer.
  • Clean all cuts and scratches with an antiseptic wipe and cover until healed.
  • Most common skin conditions of travellers can be prevented or can be treated from your First Aid kit.
  • Seek medical help for severe sunburn, spreading infections, any condition accompanied by a fever, and allergic reactions.

Motion sickness 

  • Most people will get used to the motion over several days. The reverse can happen too, when symptoms occur after the motion stops. This is known as “land sickness.” If these symptoms continue for a period of time, medical treatment may be needed.
  • Medicinal prevention can be found in many over-the-counter antihistamines. Common side effects include dizziness and drowsiness.
  • For some, non-medicinal prevention and treatment may be favoured. Things like focusing on a distant point, avoiding tasks requiring focusing up close such as reading, ensuring good ventilation, eating small, low-fat meals, and selecting a position in the most stable part of the vehicle (i.e., the mid-point of the ship) should help reduce motion sickness.

Pre-existing medical conditions 

  • If you are taking any medications, be sure to bring enough to cover your trip. Keep a list of all current medications and dosages.
  • For existing medical conditions, and recent health problems, contact your cruise line prior to travel to verify that they have the staff and the equipment you may need. For instance, if you have trouble walking, inquire to see if there is help available to board and depart the ship.
