I'm not sure anyone knows where the "Spanish" Flu originated, but it may in fact have the US. It was certainly spread by US troops. The only reason it is called "Spanish" Flu is because it happened during WW I and neutral Spain was the only country reporting it in the press, as opposed to US, UK, etc which were censoring the news so as not to look weak during wartime.
That would be an excellent point if the Spanish flu actually started in Spain. It didn't.
Knowing why you call it won't help with the feeling or this communication.
And that is exactly the issue we are trying to fix here.
