What is POH-VAU and how do you get it from seafood?

POH-VAU (Persistent Ocular Hypertensive Viral Anterior Uveitis) is an eye disease caused by a virus found in seafood and marine animals. You can contract it through handling raw aquatic animals without protection or eating raw seafood. 71.4% of cases involve frequent unprotected processing of aquatic animals or consumption of raw seafood.

What are the symptoms of the seafood virus eye disease?

Symptoms include recurring episodes of severe eye pain, extreme ocular pressure (hypertension), blurred vision, redness, light sensitivity, and seeing floaters. Repeated episodes lead to persistent high eye pressure that doesn't respond to medication, optic nerve damage, corneal damage, iris atrophy, and severe vision impairment or blindness.

Which seafood and marine animals carry this virus?

The aquatic virus (CMNV) has been detected in 49 aquatic species worldwide, including shrimp, fish, and other marine animals found in waters throughout the Americas, Europe, and Asia. The virus is particularly common in shrimp farming operations.

How is the seafood virus eye infection treated?

Treatment focuses on controlling eye inflammation and pressure with steroid eye drops, pressure-lowering medications, and in severe cases, surgical intervention. However, the condition often doesn't respond well to standard treatments, and repeated episodes can cause irreversible vision damage.

How can I prevent getting POH-VAU from seafood?

Wear protective eyewear and gloves when handling raw seafood or marine animals, avoid touching your eyes after handling seafood, thoroughly cook all seafood before eating (avoid raw or undercooked seafood), wash hands thoroughly after handling aquatic animals, and avoid splashing when processing seafood.

Is the mysterious seafood virus spreading?

Yes, POH-VAU cases are increasing, particularly in regions with high seafood consumption. The virus has been found in aquatic species worldwide, making this an emerging global health concern. Check the outbreak data above for current case reports and geographic distribution.

What is POH-VAU (Seafood Virus Eye Disease)?

Persistent Ocular Hypertensive Viral Anterior Uveitis (POH-VAU) is a newly discovered human eye disease linked to Covert Mortality Nodavirus (CMNV), a virus commonly found in marine animals and seafood. This aquatic virus causes recurring eye inflammation, extreme ocular pressure, and can lead to permanent vision loss. The disease was first identified in China in 2026 when researchers discovered that CMNV from seafood and marine animals was infecting human eye tissue.

Symptoms

Severe eye pain and redness
Extreme ocular hypertension (high eye pressure)
Blurred or decreased vision
Light sensitivity (photophobia)
Seeing floaters or spots
Recurring episodes of inflammation
Progressive vision loss
Corneal damage (in chronic cases)

Transmission

Transmitted through contact with infected aquatic animals, handling raw seafood, consumption of raw or undercooked seafood, and splashing of contaminated water into eyes during seafood processing.

Contagious Period: Not person-to-person contagious; acquired through seafood/marine animal contact

Prevention

Wear protective eyewear when handling raw seafood
Use gloves when processing marine animals
Thoroughly cook all seafood before consumption
Avoid eating raw or undercooked seafood
Wash hands immediately after handling aquatic animals
Avoid touching eyes when handling seafood
Properly clean and disinfect seafood preparation surfaces
