Scientists isolate genes that made 1918 flu lethal
Researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus. – By mixing and matching a contemporary flu virus with the “Spanish flu” – a virus that killed between 20 and 50 million people 90 years ago in history’s most devastating outbreak of infectious disease – researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.
