Letter to the editor: Diagnosis of a single imported dengue case who had travelled to Japan – how serious is it for travellers?

摘要

We enjoyed reading the meticulous clini- cal report of an imported dengue case in a German traveller returning from Japan [1]. It is, however, unclear what level of risk the ‘autochthonous’ infection of a sin- gle case in Japan represents. By investigating the epi- demiological aspects of one imported dengue case, we would like to discuss how serious the implications of autochthonous transmission are for future travellers.
