When travelling to any destination the best way to prevent illness is by planning ahead and educating yourself on the common illnesses that affect travellers visiting your intended destination. It is recommended that you visit your doctor at least six weeks ahead of your trip to find out what health advice applies to your chosen destination. You may need to take vaccinations prior to your departure to some countries, or it may be unsafe to drink local tap water without purification tablets. Also, it is recommended to monitor the time you spend in the direct sun, as well as to ensure you drink a lot of water to stay hydrated.
