Knowledge, attitudes, and practices of Japanese travelers towards malaria prevention during overseas travel

Abstract

Background: There has been some concern that Japanese travelers are not adequately protected against malaria, especially when compared to Western travelers. Multi-national studies of knowledge, attitudes, and practices (KAP) regarding malaria risk have previously been conducted in travelers.

Methods: We conducted a KAP study in Japanese travelers using the same standardized questionnaire as the previous studies. Unlike those studies, questionnaires could not be distributed at departure lounges/gates at international airports, and therefore, travelers were sourced from several different study sites, targeting different populations.

Results: A total of 212 Japanese travelers who had visited malarious areas were enrolled, of which 63.2% had visited Asia and 28.3% visited sub-Saharan Africa. Significant shortcomings in KAP were noted with respect to lack of knowledge about symptoms of malaria, poor awareness of malaria risk at their destination, and non-adherence to adequate antimosquito measures. Chemoprophylaxis use was lower among Japanese travelers than travelers from other countries, even when confining to those traveling to sub-Saharan Africa.

Conclusions: Japanese travel medicine providers and general practitioners who engage in pre-travel consultation should raise awareness of travelers about the seriousness of malaria, the need for improved compliance with chemoprophylaxis, and the importance of being properly prepared prior to departure.
