Travelers Health

Travellers Health

Before travelling overseas, it is important to be aware of the possible health risks and how to prevent problems or minimise the chances of them occurring. 

Most importantly, find out:

  • whether there are any specific health risks in the country you are travelling to for which you need to take precautions, such as malaria. 
  • how to avoid becoming ill when you are abroad
  • what to do if you become ill when you are abroad
  • how to get emergency medical treatment when you are abroad 

Common Health Risks and how to avoid them


You can reduce your risk of getting malaria

  • Use insect repellents - repellents that contain diethyltoluamide (DEET) are the most effective.
  • Wear long-sleeved shirts and long trousers whenever possible.   
  • Take anti malarial medication –  the medication is different for different strains of malaria. Some anti-malarial medication needs to be taken several weeks before you leave home.
  • Tell your GP as soon as possible if you develop a fever or an unexplained illness while you are away or indeed for up to a year after your return. 


Always use a condom, including anal and oral sex. To ensure you have a good quality condom its best to take your own supply. 

Sunburn and heatstroke

  • Do not wait until your skin feels uncomfortable before taking preventative action.
  • Cover up with loose-fitting clothes. Make sure your legs and arms are covered. Tightly woven fabrics provide the best protection from the sun.
  • Avoid direct exposure to sunlight when the sun is at its strongest
  • Wear a wide-brimmed hat and a pair of good-quality sunglasses,
  • Always use a sun protection lotion with an SPF of at least 15. If you have very fair skin, use lotions with an SPF of up to 40. Make sure that your entire body is covered by sun protection lotion. Apply sun lotion at least 30 minutes before you go out in the sun. Reapply it every couple of hours. Reapply sun lotion immediately after swimming, even if your lotion is waterproof.
  • Cloud and fog do not protect skin from ultraviolet rays.
  • Drink plenty of fluids, particularly after exercise. Isotonic drinks that replace the salt lost through sweating are ideal, but water is also sufficient.
  • Avoid drinking alcoholic drinks when you are out in the sun. 

Travellers' diarrhoea

If you are travelling in a country that has low standards of public hygiene and there is a risk of water contamination, avoid the following food and drink as they could trigger travellers' diarrhoea:

  • tap water
  • fruit juice (if sold by a street vendor)
  • ice cream and ice cubes
  • shellfish
  • eggs
  • salads
  • raw or undercooked meat
  • peeled fruit
  • mayonnaise
  • sauces 

Food and drink that are generally safe to eat include:

  • sealed bottled water that is produced by a recognised international manufacturer
  • cooked food, such as soup or stir-fry
  • canned food or food in sealed packs
  • fresh bread
  • unpeeled fruit
  • tea and coffee
  • alcohol
