Did influenza come from fish? Genes point to an aquatic origin of influenza.

Introduction

Genetic studies suggest that the influenza virus may have originated in fish. Researchers discovered a distant lineage of influenza viruses – responsible for seasonal flu, as well as the bird flu pandemic sweeping the globe – in sturgeon fish.

Genetic Evidence

Coral reefs, sturgeon fish, and other aquatic creatures bear signs of influenza infection and its distant relatives.

Previous Research

In previous studies, influenza viruses have been found in birds and mammals, but this recent discovery indicates that the origin of influenza may be in fish.

Environmental Effects

This discovery could have significant implications for our understanding of the spread and evolution of influenza in aquatic environments, and may help us develop new strategies for preventing and managing diseases transmitted through aquatic life.

Conclusion

Based on genetic evidence, it appears that influenza originated in fish. This discovery opens the door for more detailed studies on the origin and evolution of influenza, and may assist us in developing better strategies for preventing and dealing with these infectious diseases.
