An emerging opportunistic infection: fatal astrovirus (<scp>VA</scp>1/<scp>HMO</scp>‐C) encephalitis in a pediatric stem cell transplant recipient

Abstract

Neuroinvasive astrovirus (VA1-HMO-C) is an emerging life-threatening infection in immunocompromised hosts. We describe an 8-month-old child who died of VA1/HMO-C encephalitis following bone marrow transplantation. The diagnosis was only made post-mortem using RNA deep sequencing of the brain. Repeat analysis of the post-mortem brain tissue using polymerase chain reaction specific primers for VA1/HMO-C was positive. Astrovirus VA1/HMO-C should be included in the evaluation of patients with similar encephalitis.
