Sudden death from systemic rotavirus infection and detection of nonstructural rotavirus proteins

Ineko Nakano et al. J Clin Microbiol. 2011 Dec.

Abstract

A 2.5-year-old girl died suddenly during the course of rotavirus gastroenteritis. The autopsy showed encephalopathy with rotavirus systemic infection. Here, we provide evidence of rotavirus replication in multiple organs. Our findings clarify that rotavirus infection in children can extend beyond the intestinal tract through viremia.
