Virus from seafood is linked to a persistent eye disease in humans

A virus that typically infects marine animals, such as shrimp and fish, has jumped to humans and is causing chronic eye disease in some people, according to a study published in the journal Nature Microbiology. In recent years, the number of people in China with a condition called persistent ocular hypertension viral anterior uveitis (POH-VAU) has been increasing with no clear explanation as to why. Symptoms include extremely elevated eye pressure and inflammation.
