Objective: The aim of this study was to evaluate attitudes towards the available preventive measures, risk behaviour and health problems in Czech travellers to tropical and subtropical regions.
Materials and methods: The prospective study included patients of all ages with a history of recent travel to risky countries who presented to the post-travel clinic of the Hospital Na Bulovce in Prague within two months after return, from February 2009 to June 2018. The data were collec-ted through a questionnaire survey and from electronic medical records.
Results: Nine hundred and thirty-four patients (473 M and 461 F, age median of 32 years, IQR 27-39) participated in the study. The most frequent destinations were South-East Asia (332; 35.5%), South Asia (176, 18.8%), and Sub-Saharan Africa (172; 18.4%). The most common reasons for tra-vel were tourism (772; 82.7%) and business (111; 11.9%). An underlying chronic disease was reported by 317 patients (33.9%). Pre-travel health consultation was sought by 415 travellers (44.4%); however, only 312 (33.4%) of the respondents were properly vaccinated. Preventive malaria chemoprophylaxis was indicated in a total of 151 travellers (16.2%) but was only received by 44/151 patients (29.1%). Risky eating or drinking behaviour was admitted by 832 (89.1%) respondents and low standard accommodation by 525 (56.2 %) travellers. The most commonly reported clinical syndromes were acute and chronic diarrhoea (266; 28.5%), febrile illness (240; 25.7%) and skin lesions (166; 17.8%). A total of 199 patients presented with tropical infection (21.3%) and 63 with a vaccine-preventable infection or malaria (6.7%). Conclusions: The study shows that the adherence of Czech travellers to preventive measures is relatively low, and along with risky behaviours, has a significant impact on travel-related morbidity. However, vaccine-preventable infections only accounted for a small fraction of travel-related illness, which is in accordance with other epidemiological studies and points out the need for a more comprehensive interdisciplinary approach to pre-travel health consultations.
