Those travelling for extended periods or taking up residency in developing countries or tropical regions are at increased risk of developing diseases specific to that area. For example, the adventurous long-term travellers that tend to wander “off the beaten track” are at an increased risk of developing malaria or gastrointestinal infections.
Expatriates or those relocating overseas must take into consideration the same infectious diseases as the short-term traveller in addition to other factors. How to manage any existing medical problems overseas, the stresses associated with relocating and living in a foreign country, and the stresses of social interaction, particularly if language is a barrier, all need to be considered and should be discussed with your organisation. It is also important to have a baseline check up with your GP as well as a dental check-up prior to departure.
Those who are living or working overseas may benefit from speaking to local health authorities prior to departure and also while away. Find local medical facilities soon after arrival so that you are prepared should a medical emergency arise but beware of obtaining anecdotal advice from other expatriates, as this may not be accurate.
