Enterovirus and Parechovirus Coinfection in a Sudden Unexpected Infant Death.

ABSTRACT

Viruses are suspected to play a role in the multifactorial pathogenesis of sudden infant death. We described a sudden and unexpected death in a 5-month-old boy, with detection of both enterovirus and parechovirus RNA in the blood. This is the first report of a dual viraemia of enterovirus and parechovirus and its potential association with a sudden unexpected infant death. Extensive sampling and testing especially using molecular methods currently available is needed to better understanding the "hypothetical" link between viral infections and sudden infant death.
