Brain infections and inflammation may explain some cases of sudden infant death syndrome (SIDS), a small study hints.
The research pointed to a specific virus, called human parechovirus 3 (HPeV3),as potentially tied to the death of one child in the study; HPeV3 is known to cause both mild respiratory infections and severe nervous-system infections. At this point, the virus can't be definitively confirmed as the child's cause of death, but the study highlights the idea that some SIDS cases may stem from viral infections and that this notion bears further investigation.
