Travel medicine: a perspective on the emerging problem of travel-related infections.

Travel Medicine has come a long way since it was started in the 1980s. Today, with the advances in electronic communications and efficient international travel, the demand for up-to-date information on international health situation is more urgent than before. Disease outbreaks can be updated and be available immediately across to the whole world in a matter of hours via the Internet. Travel medicine specialists no longer can give the excuse that they are unaware of such a situation because it is posted all over the net. Advances in vaccine development and the work of international agencies like the World Health Organization and the Centres for Disease Control have helped further the strategies and the knowledge we have in travel health risks. For the traveller, this means that they should no longer be travelling to a destination without knowing the health hazards and without taking the appropriate prophylaxis and precautions.
