Euro Surveill. 2017 Aug 24;22(34):30600. doi: 10.2807/1560-7917.ES.2017.22.34.30600.

Abstract

We describe the dynamics of dengue virus (DENV) infection in a woman in her mid-30s who developed fever after returning from Sri Lanka to Italy in April 2017. Laboratory testing demonstrated detectable DENV-RNA in plasma, urine, saliva, vaginal secretion. Persistent shedding of DENV-RNA was demonstrated in vaginal secretion, and DENV-RNA was detectable in the pelleted fraction up to 18 days from symptom onset. These findings give new insights into DENV vaginal shedding and vertical transmission.

Keywords: Dengue; Zika; flavivirus; sexual transmission; vaginal secretion; vaginal shedding; vertical transmission.
