Case in brief

A 41-year-old woman in southeastern China presented with fever and myalgia, testing positive for dengue virus serotype 1 (DENV-1) RNA and NS1 antigen, indicating early acute infection. Her husband, who had dengue prior to returning from Timor-Leste, had unprotected sexual intercourse with her shortly after his return. Despite undetectable DENV RNA in his blood, it was found in his semen, suggesting probable sexual transmission.

Diagnostic / clinical pearl

Clinicians should consider sexual transmission of dengue virus in cases where local mosquito-borne transmission is unlikely, especially when a recent travel history to endemic areas is present.
