[Tourism and health: methodological approaches and courses of action]

To identify relationships between tourism and health as well as the methods employed in studies about this topic.

The PubMed and SciELO databases were searched in March of 2008 using the following strategy: traveler or traveller or tourism or tourist AND risk or hazard or vulnerability AND health or surveillance. The following were excluded: articles on animal health, conceptual and review articles, articles about non-tourist travel, and articles written in languages other than Portuguese, English, Italian, and Spanish. Of 153 articles identified, 112 were excluded, and 41 articles were examined.

The number of articles on tourism and health increased from one in the 1970s to 34 in the 2000s. Most studies were carried out in Europe, followed by the Americas, and most covered insect-borne diseases, respiratory diseases transmitted from person to person, and gastrointestinal diseases. Mail, telephone, or face-to-face questionnaires were generally used for data collection. In terms of location, 21 studies were performed at the place of departure, 17 at the destination, and in 3 this information was not specified. Four studies were carried out before the trip, 9 during the trip, 24 after the trip, and 3 did not specify this information. Most studies focus on the tourist as a likely victim of health problems, unprepared to face situations of exposure during the trip.

The need to implement health care policies aimed at the tourist population is evident, with emphasis on infectious diseases and emergency actions to detect outbreaks involving tourists. A tourist-specific surveillance and notification system is also necessary, together with measures to prepare health care institutions to meet the individual demands of this population.
