HIstory EE- spanish flu - help with research question

[alpineadam]

I want to do a history EE on the spanish flu but I am having trouble finding a specific enough question that still relates mainly to history.

I had an idea where I would inquire whether the post war conditions of WW1 or the actual flu (genes) was the catalyst that made the spanish flu so deadly

However, after initial research it seemed to be too much based around biology (which I don't take) with research about what the spanish flu did to the body.

I would just like some ideas fro formulating a good research question for the spanish flu. Whatever the question is I would like the answer to somewhat be a recollection of what the spanish flu did and how it affected people and society.
