Travel medicine: an Australian perspective.

Travel medicine is emerging as a new multidisciplinary specialty area catering for an increasing number of travellers worldwide. Travel health advisers are engaged in the provision of pre-travel health advice, chemoprophylaxis against travel-related diseases, traveller's medical kits, and post-travel assessments and eradication treatment for various travel-related diseases. They are also in a key position to liaise with public health authorities on possible imported disease risks. In terms of risk assessment and provision of preventive measures, vector-borne diseases, in particular malaria and the arboviral diseases, stand out as major concerns for travellers, however, common problems, such as travellers' diarrhoea and respiratory tract infection, also need to be addressed. Travel and aviation medicine have many linkages, especially in terms of fitness to fly and dealing with problems that may arise in travellers due to physiological and psychological stresses of travel. In the face of recent terrorism and conflict, travel advisories have assumed great importance in travellers planning. Travel insurance remains an important safety net for travellers, which provides coverage for medical and dental treatment abroad as well as an emergency assistance service, which may include aeromedical evacuation.
