Scientists have discovered a new gene in the influenza virus that helps the virus control the body's response to infection. Although this control is exerted by the virus, surprisingly it reduces the impact of the infection. The findings will help researchers better understand how flu can cause severe infections, as well as inform research into new treatments. Researchers found when the virus gene – called PA-X – was active, mice infected with flu subsequently recovered.
