Using genes resurrected from the 1918 Spanish influenza virus,the virus responsible for a pandemic that killed an estimated 20 million people,scientists have gathered important new clues to why the virus spread quickly and killed efficiently. Adding the genes to a comparatively benign strain of influenza (pictured),shows that a minor genetic change can turn a mild form of the virus into a highly virulent strain | |
