Cold May Help Prevent Flu Says New Study

The virus most often behind the common cold is capable of preventing the flu virus.
It prevents the flu from infecting airways by jump-starting the body's immune defenses.
A study published Friday by The Lancet Microbe found this evidence recently.
They did an analysis of more than 13,000 patients with symptoms of a respiratory infection.
Those who had rhinovirus were not simultaneously infected with the flu virus.
Now researchers want to determine if rhinovirus offers similar protective effects against COVID-19.
