Summary

Norovirus commonly causes gastroenteritis. In a rare case, a child developed encephalopathy, with the norovirus genome detected in cerebrospinal fluid, suggesting a potential causal link.

Background:

Norovirus is a leading cause of acute gastroenteritis globally.
Encephalopathy is a complex neurological condition characterized by altered brain function.

Observation:

A 23-month-old girl presented with encephalopathy.
Norovirus infection was suspected as a potential cause.

Findings:

The norovirus genome was identified in the patient's stool, serum, and cerebrospinal fluid (CSF).
Reverse transcription polymerase chain reaction (RT-PCR) confirmed the viral presence.
This marks the first documented instance of norovirus genome detection in CSF in a case of encephalopathy.

Implications:

This case suggests a potential direct role of norovirus in causing encephalopathy.

Further research is warranted to understand the mechanisms of norovirus-associated neurological complications.

Highlights the importance of considering viral etiologies, including norovirus, in pediatric encephalopathy cases.
