Staying healthy on a cruise

​​​Going on a cruise ship can increase your risk of catching illnesses, such as COVID-19, influenza (flu), and gastroenteritis (gastro). Viruses can spread quickly when large numbers of people spend time together, especially in indoor spaces.

Learn how to prepare for your cruise, protect yourself while onboard, and what to do if you become unwell.

Before your cruise

 

If you are feeling unwell, tell cruise staff before boarding and follow their advice. This helps cruise operators identify and manage outbreaks and protect the health of passengers and crew.

Know if you are at higher risk of severe illness

People at higher risk of severe illness include older people, pregnant women and people with certain health conditions, such as:

  • diabetes
  • obesity
  • heart disease
  • chronic kidney disease
  • weakened immune system
  • neurological disease, such as stroke or dementia
  • chronic lung disease, such as severe asthma or chronic obstructive pulmonary disease.

If you are at higher risk, talk to your doctor. They can help you understand your risks, decide if you need extra precautions, and prepare for what to do if you become unwell during your cruise. ​They may also provide an antiviral pre-assessment form for you to take with you, in case you test positive to COVID-19 or flu.

Get any vaccinations you need

Make sure your vaccinations are up-to-date, including COVID-19 and flu vaccinations.

You may also need additional travel vaccinations depending on your destination.

Talk to your doctor, pharmacist or travel health clinic at least 6 to 8 weeks before departure, as some vaccines take time to become effective.

Pack your medicines

Ask your doctor what medicines you should take with you in case you become unwell during your cruise. This may include medicines to help manage COVID-19, flu, gastro or other common travel-related illnesses.

If you take prescription medicines, keep them in their original packaging and carry them with a doctor’s letter explaining what they are for.

Check with your cruise operator or travel agent

Cruise operators have procedures to help protect the health and safety of passengers and crew.

Make sure you understand what will happen if you become unwell. You may be asked to stay in your cabin or need to be transferred to a hospital at the nearest port.

Check with your cruise operator or travel agent if there is anything else you need to know or do before boarding.

Review your travel insurance policy

Keep in mind that there may be significant additional costs and charges if you require medical care. Speak to your cruise operator or travel agent about potential fees. Check if your travel insurance covers medical expenses that the cruise line doesn’t cover, such as medications or the cost of being transferred from the ship to a hospital.

During your cruise

Viruses can spread very quickly on cruise ships, through shared spaces and contaminated surfaces.

  • Wash your hands regularly with soap and water and use hand sanitiser.
  • If you start to feel unwell, stay in your cabin as much as you can and tell cruise staff as soon as possible.
  • If you have cold or flu symptoms, or test positive to COVID-19 or flu, wear a mask when outside your cabin and avoid crowded areas.

After your cruise

After returning home, monitor your health and take steps to help prevent the spread of illness if you become unwell. Some infections may not cause symptoms until after your cruise has ended.

See a doctor promptly if you develop:

  • cold or flu symptoms, such as runny nose, sore throat, cough or fever
  • gastro symptoms, such as nausea, vomiting, diarrhoea or fever.

Always tell your healthcare provider where you have travelled.
