"The 1918 influenza p******c was the most severe p******c in recent history. It was caused by an H1N1 v***s with genes of avian origin.
Although there is not universal consensus regarding where the v***s originated, it spread worldwide during 1918-1919.
In the United States, it was first identified in military personnel in spring 1918.
It is estimated that about 500 million people or one-third of the world’s population became infected with this v***s.
The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States."
