Viruses are small, non-cellular life forms that must infect host cells to propagate. Many of mankind’s most dreaded diseases are caused by viral pathogens, and much virus research is focused on making discoveries to alleviate or prevent viral diseases.

The study of viruses has also played a seminal role in our understanding of molecular biology, cell biology, immunology, and cancer biology. Yale has a rich tradition in virus research that continues to thrive.

Beyond the Department, many other Yale researchers study viruses. Additional information can be found on the Yale Molecular Virology.
