Dengue virus infections among European travellers, 2015 to 2019.

ABSTRACT: BackgroundDengue is a disease with major impacts on public health in tropical and subtropical countries.

We investigated the following associations: (i) between TIR and incidence rate in selected countries of infection and (ii) between number of travel-related cases and occurrence of autochthonou
