Two cases of dengue virus type 2 (DENV-2) infection in a Japanese couple returning from Maldives in the dengue outbreak in 2018

Annually, more than 1.2 million travelers from other countries visit the Maldives for sightseeing, business, and honeymoon. In 2018, the largest dengue fever outbreak occurred, affecting more than 3,200 people. During this outbreak, we encountered a newly married Japanese couple returning from the Maldives on their honeymoon in October 2018, both were infected by the dengue virus type 2 during the travel. The number of imported dengue fever cases from the Maldives may increase; hence, physicians should stay up to date on dengue outbreak information worldwide.
