Spanish flu
Diffuse
It diffused all across the world. It spread just like the flu does today. From being around people touching different thing and then putting your hands by your face without cleaning them.
In 3 waves the Spanish flu spreaded quickly, killing 50 to a 100 million people around the world.
Where did it start?
The Spanish flu started in Spain. It traveled really fast through army camps getting many of the troops sick and many dying.
What was the cause of the out break/what where the effects of the diffusion
The cause of the out break was that people where living so close together and not staying very clean. Some of the effects of this where that the population went down. Many people where dying all across the world.
The time period
The time period was January 1918 from December 1920
How did it come to a end?
Doctors came up with a vaccination to stop the Spanish flu. If it was not for this it would have lasted for a lot longer time. Killing many more people then what it already had.
