Keeping healthy when travelling
Find out how you and your whānau can keep healthy when travelling.
Before you travel
Check with your healthcare provider or travel doctor to see if you need any immunisations. Try to do this 6 to 8 weeks before you leave.
As a minimum, you should make sure that all your routine immunisations are up-to-date such as tetanus, measles, and polio vaccinations.
Diseases to be aware of when you travel
There are certain types of diseases to be aware of when you travel including diseases spread through:
- coughing and sneezing
- contaminated food, water or poo (faeces)
- sexual contact or blood and body fluids
- mosquito and other insect bites.
Diseases that are spread through coughing and sneezing
Some diseases that are spread through coughing and sneezing include:
- flu (internal link)
- COVID-19 (internal link)
- measles (internal link)

Protect yourself and others
- Consider wearing a well-fitting mask when you are in close contact with others – particularly in crowded indoor spaces.
- Wash hands frequently and dry thoroughly. It can be useful to carry hand sanitiser in case you do not have access to soap, hot water and a clean towel.
- Do not share drinks.
- Cover your mouth and nose when you cough or sneeze.
Measles
Measles is a serious and highly contagious disease spread through coughing and sneezing. It can cause severe problems, including brain swelling, chest infections, or death. Right now, there are measles outbreaks happening around the world. If you are travelling overseas make sure you are fully immunised against measles before you go. The measles vaccine is very effective at preventing measles.

About the Measles (MMR) vaccine
- If there is not enough time before you travel to complete the recommended 2 doses, having even one dose of the MMR vaccine before you leave Aotearoa New Zealand will significantly reduce your (or your child’s) risk of getting infected.
- It is best to have your vaccination at least 2 weeks before you travel, if possible.
- Babies under 12 months may also be able to be immunised for measles before travelling. Ask your healthcare provider if your pepi can have the MMR vaccine.
- You can get your MMR vaccine at your healthcare provider, or some local pharmacies.

Information about mosquitoes and other insects
Mosquitoes
Mosquitoes that carry malaria, West Nile fever or Japanese encephalitis are more active in the evening and at night. If you are travelling in an area that has these diseases, be careful at those times.
Mosquitoes that carry dengue, yellow fever or zika are more active in the daytime, are silent and prefer to bite the ankles.
Tsetse flies
Tsetse flies are large flies found in mid-continental Africa, particularly in vegetated areas. Their bite can cause sleeping sickness. Sleeping sickness symptoms include fatigue, high fever, headaches, and muscle aches.
Ticks
Ticks are common in a variety of climates, including warm, humid climates such as the Australian bush, as well as temperate climates or anywhere large mammals thrive. They can carry many diseases.
Avoiding insect bites while travelling
To avoid diseases spread by mosquitos and other biting insects when travelling outside Aotearoa New Zealand, take precautions to prevent bites.
Wear long, loose fitting, light coloured clothing - you can see ticks are more easily on a light background and tsetse flies are attracted to dark, contrasting colours.
Repel
- Use a repellent, preferably containing diethyltoluamide (DEET, less than 35%), Picaridin, IR3535, Oil of lemon eucalyptus (OLE), Para-menthane-diol (PMD), or 2-undecanone. Always read the instructions before applying.
- Apply repellent after sunscreen.
- Spray clothing with an insecticide such as permethrin.
Important repellent information
- High concentrations of DEET protect better, but concentrations over 35% (about 350 g/L) are not recommended if there is a choice of products available. This is because in rare cases they can cause poisoning.
- Other products containing 20–25% picaridin (about 200–250 g/L) and those containing about 30% oil of lemon eucalyptus (equating to about 20% para-methane-diol (PMD)) can also be used.
- Repellents should not be applied to wounds, irritated skin, eyes or mouth.
- Vitamin B does not prevent mosquito bites.
- Stay in places with screens on windows and doors or sleep under mosquito nets.
- Use air conditioning or fans if available.
- Use insect sprays indoors when mosquitoes are around, even if you are not able to see them.
- Use mosquito coils.
- Stay away from places where mosquitoes are most active or breeding such as stagnant water.
- If you are camping, use zip-up screens on tents.
