Chinese researchers have identified a virus found in aquatic animals that can infect human eyes and cause potential vision loss [1].

This discovery highlights a significant cross-species transmission risk, as the pathogen can move from marine environments to humans through direct contact. The findings suggest that the way people interact with seafood may directly impact ocular health.

The virus has been detected in more than 20 aquatic species [4]. According to the research, the infection can lead to glaucoma-like symptoms, which typically involve increased pressure in the eye, and damage to the optic nerve [1].

Exposure to the pathogen is linked to the handling or consumption of raw seafood [1]. Researchers said that the risk of infection increases for individuals who engage in these activities, as the virus persists in farmed and wild marine animals [2].

While the study identifies the ability of the virus to jump species, the researchers focused on the specific ocular damage caused by the infection [3]. The potential for permanent sight impairment makes the identification of this virus a priority for public health monitoring in regions with high seafood consumption [1].

Health officials have not yet issued formal mandates, but the study emphasizes the link between aquatic animal health and human medical outcomes [2]. The presence of the virus across a wide variety of species suggests it is well-adapted to marine environments, making it a persistent threat to those in the seafood industry [4].

“A virus detected in aquatic animals can infect human eyes, causing glaucoma-like symptoms.”

The identification of a zoonotic virus targeting the human eye underscores the growing concern over spillover events from aquaculture and wild fisheries. Because the virus is present in a diverse range of species, it suggests a broad environmental reservoir that could make eradication difficult, potentially requiring new food safety protocols for raw seafood handling to prevent ocular disease.
