What is travel medicine? It is a science and an art

What is travel medicine? § It is that part of health professional practice that: – seeks to prevent illnesses and injuries occurring to travellers going abroad – manages problems arising in travellers coming back or coming from abroad – is concerned about the impact of tourism on health and also advocates for improved health and safety services for tourists – is increasing concerned about refugee and migrant health (Primer of Travel Medicine 3 rd Ed)

§ “the art of travel medicine is selecting the necessary prevention strategy without unnecessary adverse events, cost or inconvenience” (Steffen, 1994)

Challenge of travel medicine § Sea of global migration of people – More people travelling § People travelling further a field § Rapid movement of travellers

Travellers from industrialised areas to developing areas 1999 (WTO) 2. 8 USA / Canada 35. 2 million 2. 3 3. 6 7. 8 19 Europe 25. 0 million 6. 8 2. 5 1. 2 1. 3 2. 4 4. 6 1. 9 6. 1 Japan 11. 4 mio 4. 8 2. 6 AUS / NZ 3. 3 million n million travelers 0. 2 -1 million travelers Total: ~ 80 million travelers

Globalization of health and safety § Affects – Health of local populations – Health determinants – Safety and security § Results in – Global impacts – Emerging and reemerging infectious disease Commerce and Health Influenza Terrorism Tsunami Pathogens travel as fast as transportation: borders are not respected SARS

Travellers are exposed to a variety of hazards

The Importance of Travel Health Measures § 100, 000 travelers to the developing world for 1 month…. . – 50, 000 will become ill – 8, 000 will see a physician – 5, 000 will stay in bed – 1 will die Steffen, 1994

The Importance of Travel Health Measures § Per 100, 000 travellers that have travel insurance …. . – 8000 will make a claim (8%) – 2000 will use emergency assistance (2%) § 400 ER or clinic referrals (0. 4%) § 200 Hospital admissions (0. 2%) § 50 Aeromedical evacuations (0. 05%) Leggat et al. Travel Med Inf Dis 2005; 3: 9 -17.

The Importance of Travel Health Measures § Mortality – Cardiovascular Disease (50 to 70%) – Accidents/Trauma (20 -25%), esp. MVAs – Infectious diseases (2. 8 -4%) (Reid and Cossar, BMBull. 1993; 257 -268; Prociv, MJA. 1995; 163: 27 -30; Baker et al. , PHR 1992; 107: 155 -159; Mac. Pherson et al, JTM. 2000; 2000: 227 -233; Steffen, Trans RSTM&H 1991; 85: 156 -162 )

Travel medicine is a continuum § Travellers do get sick or injured abroad or when they come back § The commitment to travel health can therefore be regarded as a continuum

The Continuum of Travel Medicine Pre-Travel Preventive Medicine Visitors Contingency During Travel Planning Treatment & Rehabilitation Post-Travel
