Seafood Virus CMNV Linked to Emerging Human Eye Disease

A Nature Microbiology study links the shrimp-associated virus CMNV to an emerging human eye disease called POH-VAU, finding CMNV-like particles and antibodies in patients and showing similar symptoms in CMNV-infected mice; most cases involved direct exposure to raw seafood, but some occurred without clear exposure, raising concerns about potential human transmission and ocean-based zoonoses, with CMNV detected in 49 aquatic species—more research is needed to confirm causality.
