Scientists Resurrect Deadly Flu Virus

In a contained laboratory at the federal Centers for Disease Control and Prevention in Atlanta, scientists used reverse genetics to re-create the 1918 flu virus that killed 20 million to 50 million people, according to studies released Wednesday.
The 1918 virus's jump from birds to humans, perhaps through intermediary animals such as pigs, was different from the two other outbreaks of pandemic influenza that occurred in the 20th century. Those pandemic strains in 1957 and 1968 occurred when novel influenza genes mixed with existing human influenzas.
