Health Tips for the Cook Islands

The Cook Islands presents a few environmental hazards but very few diseases. Like travelling anywhere in the world, it’s smart to have your travel vaccinations up-to-date and to prepare a first aid kit for injuries or minor health issues that might occur. See our advice in What Medication to Pack in Your First Aid Kit for the Cook Islands and Do You Need Vaccines to Travel to the Cook Islands?

Medical Issues That Can Occur in the Cook Islands

The most common medical issues that can occur in the Cook Islands are sunburn, heatstroke, mosquito bites and coral cuts. These are very easy to keep in check with simple precautions. Other medical issues may occur when it comes to drinking water and food, which we cover in our “Food and Water Hygiene” section.

Heat Stroke

Overexposure to the sun and high humidity can lead to heatstroke. Symptoms include exhaustion, confusion, headache and vomiting. To avoid, wear high-factor sunscreen, reapply every three hours or straight after swimming, and drink plenty of water. If symptoms occur, move out of the sun immediately and try to cool the victim down by wrapping a wet towel around them. See a doctor as soon as possible. For more sun protection tips, check out The Best Sunscreens for the Cook Islands + Sun Protection Tips.

Mosquito Bites

Mosquitos can leave a nasty itchy bite, which is enough to ruin an evening under the stars. What’s more, day-biting mosquitos transmit dengue fever (see below). Check out 12 Ways to Avoid Mosquito Bites in Rarotonga & the Cook Islands for ways to avoid bites.


Ciguatera is fish poisoning caused by eating reef fish that have eaten particular types of toxic algae. Symptoms occur within 24 hours of eating contaminated reef fish and include vomiting, diarrhoea and numbness in the fingers. The best way to prevent it is to avoid eating reef fish altogether; eating deep-sea fish, like tuna, wahoo and mahimahi, is fine.

Coral Cuts

Cuts from live coral can leave prolonged infections, so if you are injured by live coral, get out of the water immediately and cleanse the wound. Take out all of the bits of coral, apply antiseptic cream, and cover with a dressing. You should have all this stuff in your Cook Islands First Aid Kit!

Diving Decompression

Scuba diving is a popular activity in Rarotonga and Aitutaki, but neglecting the strict depth and timing precautions of scuba diving can result in decompression illness, otherwise known as “the bends”. Note that there are no decompression chambers in the Cook Islands.

Infectious Diseases

Dengue Fever

Dengue fever is a mosquito-transmitted disease that has regular outbreaks in the Cook Islands. It is only the day-biting mosquitos (black and white striped) that cause the infection, so take a precaution by preventing mosquito bites. See the 12 Ways to Avoid Mosquito Bites in Rarotonga & the Cook Islands for tips.

E-coli (Traveller’s Diarrhoea)

E-coli is a virus resulting from food and water that is contaminated with faecal matter, for instance. Precautions to take include boiling water for at least 10 minutes if the water is not from a safe source and washing hands regularly. See Is the Water Safe to Drink in Rarotonga & the Cook Islands? for more tips. Symptoms include fever, drowsiness and diarrhoea. If symptoms occur, hydrate by taking small sips of fluids continuously, alternating between electrolytes and water. If you don’t have an electrolyte solution, drink Coca-Cola or salty broth. In most cases, you will need to wait out the symptoms, as antibiotics rarely treat E-coli effectively.


The COVID-19 virus has been present in the Cook Islands. Symptoms are flu-like including fever, cough, tiredness and loss of taste or smell. It is recommended that you are fully vaccinated before travelling to the Cook Islands. See Do You Need Vaccines to Travel to Rarotonga & the Cook Islands? for more details.

Natural Disasters in the Cook Islands

Although the Cook Islands is usually blessed with buckets of sunshine, its location in the South Pacific means that it is at risk of extreme weather events and natural disasters.


The South Pacific cyclone season runs from November to April. On average, the Cook Islands experiences a big cyclone once every five or so years (but in 2005, they got five cyclones in five weeks)! The Cook Islands is well prepared for cyclones, however, so check out Cyclones in the Cook Islands: A Guide to Cyclone Safety in the Cook Islands for advice on safety precautions.


Being a little out of the way from major earthquake zones, the Cook Islands has rarely been impacted by tsunamis. Regardless, the country has tsunami protocols in place, as it is at risk. Find out more in The Guide to Earthquakes & Tsunamis in the Cook Islands.

Dangerous Animals in the Cook Islands

The Cook Islands doesn’t have any poisonous spiders or snakes (one of the 21 Fun Facts About Rarotonga & the Cook Islands) but there are venomous fish, as well as other animals that you’re best to avoid. These include:

  • Aedes aegypti – The day-biting mosquito that can transmit dengue fever
  • Stonefish – Camouflage fish that have venomous spines
  • Centipede – Will leave a painful bite if provoked
  • Crown-of-thorns starfish – Has venomous spikes
  • Fire coral – Has bright yellow branches and leaves a nasty sting or rash
  • Lionfish – Fish that leaves a painful sting
  • Man o war jellyfish – Rarely seen but they can get carried over reefs after storms

Food and Water Hygiene

Where most travellers visit in the Cook Islands, there is safe drinking water available and food prepared and/or packaged to a safe standard. On remoter islands, there is more likely that there will be water or food that doesn’t “agree” with you, even if the locals drink/eat it every day. We go over a few food and water hygiene tips for the Cook Islands here.

Know What Water is Safe to Drink

Tap water in most tourist accommodations is safe to drink, as many have their own filtration system installed but always be sure to ask where to get safe drinking water (as it’s not always from your bathroom’s tap!) as well as in resorts that often have their own water filtration system. There are also filtered public water stations around Rarotonga and Aitutaki. Otherwise, in villages and remote areas the water may not be safe to drink, even if the locals are drinking it – they are usually used to it.

To avoid water-borne diseases, such as traveller’s diarrhoea, boil water for about 10 minutes before drinking it. Water purifying tablets and Lifestraw bottles also help, but boiling water is the safest option. See Is the Water Safe to Drink in Rarotonga & the Cook Islands? for much more of a deep dive into the subject.

Focus on Hygiene Especially When Staying in Remote Areas

Staying on a remote island can be an enriching cultural experience, but you will need to accept a small portion of risk with conditions being so remote and different from home. First, focus on hygiene by washing your hands regularly or using a hand sanitiser, especially before eating food. In the unlikely case that you do start feeling ill, act quickly by seeking medical attention, even if it means returning to Rarotonga. If you let the situation worsen, it may be very strenuous to wait to see a doctor.

Be Aware of Food Safety

Eating in restaurants or at tourist accommodation is usually very safe in the Cook Islands. But if you’re eating in a remote area, then there are a few things to be aware of. For instance, if you’re in an area that may have unsafe water, avoid eating salads or uncooked food that might have been washed with contaminated water. Preferably, eat food that has been cooked in front of you. Vegetarian food is usually the safest option.

To avoid gastro bugs, use hand disinfectant and only eat cooked food. If you get diarrhoea, drink water regularly and alternate between electrolytes and water. If other symptoms occur, see a doctor.

A common type of food poisoning in the Cook Islands is ciguatera caused by eating reef fish that has eaten toxic algae. Avoid eating reef fish and just stick to the deep-sea stuff.

Finally, avoid salmonella by not eating runny eggs or undercooked meat. If you have blood in your stool, see a doctor immediately.

Crimes Against Tourists in the Cook Islands

The Cook Islands is generally very safe when it comes to crime, while tourist scams are unheard of. However, there is the occasional petty crime, like theft and accommodation break-ins in cases where valuables are on display or accommodation is not secured.

Beach locations are higher-risk areas for theft of unattended items, so make sure that you don’t leave bags or valuables in vehicles, scooters or on bicycles and lock your vehicles. If you have accommodation on the beach (or anywhere, for that matter), make sure that you lock your door.

Theft is not something to be too worried about in the Cook Islands, but a bit of commonsense precaution is always advised.
