Did a marine virus jump to humans causing vision loss for the first time?

Analysis Reasoning

The post claims a marine virus has jumped to humans for the first time and is causing vision loss. This is TRUE. A covert mortality nodavirus (CMNV) originating from marine animals has infected 70 documented patients in China since early 2022, causing persistent ocular hypertension viral anterior uveitis (POH-VAU)—a condition with glaucoma-like symptoms and irreversible vision loss in some cases. Researchers confirmed this is the first documented spillover of an aquatic virus directly causing disease in humans, with findings published in Nature Microbiology in April 2026.
