The Spanish Flu is a really interesting case. Here is what I found last time I researched it:
The outbreak happened during WWI, and there were tight controls on media among the belligerent nations. So the nations among which it likely originated were suppressing info on the virus for the same reason they were suppressing info about the brutality of the war, to avoid crushing the moral of the people with bad news. Spain, being neutral, reported the effects of the virus more freely, so it became associated with it before the other nations did, hence the Spanish Flu.
I think it originated somewhere on the western front where millions of men were living in filth and blood, constantly interacting with insects and rats and dead bodies, and disease generally ran rampant.
And the Spanish Flu
