- An estimated 50 million people died from the influenza virus that swept the world in 1918, killing more than any other illness in recorded history.
- The virus first appeared in spring 1918 with mild symptoms but returned in fall in a more severe form, as scientists and doctors did not understand why it was spreading so quickly.
- Symptoms were atypical and included hemorrhaging in the lungs, with many victims' lungs filling with fluid and causing suffocation within hours.
- Medicine at the time could not cope with the virus, and while home remedies helped symptoms, there was no cure identified as the virus eventually subsided on its own.
