Vertically transmitted dengue in a neonate born to a mother with asymptomatic dengue infection

Historically, dengue was known to be a vector borne disease. There is a wide clinical spectrum of disease ranging from a non-specific acute febrile illness, dengue fever (DF) to dengue haemorrhagic fever (DHF) and dengue shock syndrome. Some can remain asymptomatic. Vertical transmission of dengue infection is well known yet rare. In almost all the reported cases, the neonate was diagnosed after their mothers were identified as having dengue. We report a case of DF in a neonate, whose mother had asymptomatic infection, which was identified following the diagnosis of her newborn.
