Preventive measures, risk behaviour and the most common health problems in Czech travellers: a prospective questionnaire study in post-travel clinic outpatients.

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.
