Researchers have found a way to predict whether someone exposed to the flu virus is likely to become ill.

Purvesh Khatri, PhD, associate professor of medicine and of biomedical data science, and his team used a computational approach to pinpoint a blood-based genetic biomarker to determine an individual’s susceptibility to the disease.

“We’ve been after this for about four years,” Khatri said. “To our knowledge, it’s the first biomarker that shows susceptibility to influenza, across multiple strains.”

The biomarker is a gene called KLRD1, and it essentially acts as a proxy for the presence of a special type of immune cell that may be a key to stamping out nascent flu infection.
