  • A study published in March 2026 describes a new human eye disease
  • The disease is associated with covert mortality nodavirus (CmNV
  • CmNV was previously found in shrimp and is now linked to humans

Researchers have documented a newly recognized human eye disease that has been connected to a virus originally detected in aquatic animals, according to a study published in Nature Microbiology on 26 March 2026.

The virus, known as covert mortality nodavirus (CmNV), was previously identified in shrimp species, including whiteleg shrimp, and has now been found to be associated with persistent ocular hypertensive viral anterior uveitis (POH-VAU) in humans.

The Nature Microbiology study provides genomic evidence supporting the zoonotic transmission of CmNV from shrimp to humans. This finding marks the first time CmNV has been linked to a human disease, expanding its known host range beyond aquatic animals.

CmNV is classified within the Nodaviridae family and has been studied in the context of shrimp farming, where it has caused health issues in various shrimp populations. The new research indicates that the virus is capable of infecting humans and causing specific ocular conditions.

What the numbers show

  • The study was published on 26 March 2026
  • CmNV was previously known to infect whiteleg shrimp
  • The newly described human disease is termed POH-VAU

The identification of CmNV as the cause of POH-VAU was based on genomic analysis conducted by the research team. The study's findings highlight a direct link between the virus in shrimp and the emergence of disease in humans.

Prior to this research, CmNV had only been characterized in aquatic environments, particularly in commercial shrimp farming, where it was recognized as a pathogen affecting shrimp health. The new evidence demonstrates that the virus is not limited to aquatic hosts.

The study's authors state that the transmission of CmNV from shrimp to humans represents a documented instance of zoonotic infection. The research underscores the importance of monitoring viruses in aquatic animals for potential impacts on human health.

Further investigation into the transmission pathways and prevention strategies for CmNV is anticipated, following the publication of these findings. The study establishes a foundation for future research on zoonotic viruses originating from aquatic sources.
