The Spanish Flu probably started in China but that is unknown. When the first case of the Spanish Flu in the US was reported case in Kansas most people did not expect it to be as bad as it turned out to be!
Many people say that the flu could have been caused from chemicals or harmful gases. The 1 thing we know is that it started in animals and then was spread to humans.

The Spanish Flu of 1918 to 1919 infected and estimated amount of 500 million people and it killed about 20 to 50 million people that were effected by it.
In many cases the flu infected the lungs and caused pneumonia.
The Flu mainly targeted young children because it went through the immune system, since their immune system is very weak( I am not saying that adults and elders where not effected by the Flu).
Spain gave the Spanish Flu it's name because it was one of the first countries to be hit by the flu.
There were 2 waves of the flu, the first wave was not super bad, but yet it was still a terrible disease, and the second wave was when most of the people with the disease died.
IN this battle I think that 2016 would win, but not because it was not as widespread but because back in 1918 they did not have all of the modern medicines that we have today so their was no way to get better. Imagine you had strep throat but there was no medicine to heal you so you had strep for a lot longer time then you would today(thank you whoever invented medicine). That's what it was like back then, either life or death.
