The Spanish Flu according to Mossy:
As Usual there is too much info..contra info out there..But..here is my Take on it.
Spanish Flu was traced back to a US Farmer who picked it up off wild birds on the farm.
He got called up for WW1...and it spread through the troop tents while they were waiting to sail to Europe.
Then they got on the troop ships........for weeks...and it did the same as the cruise ships this time round....
It Percolated it.
2 or 3 get On with it....weeks of close quartered confinement and they literally were Plague ships.
They docked in UK Europe.....and it spiraled along all the main highways and train tracks that people traveled to.
Once it did that...it is like ripples on a pond....the waves get bigger and bigger.
Then..the war ended...the troops set back off for the US...on troop carriers......sigh...you see the pattern here...
Percolated it....and landed it en mass back in the US.
Troops set off back home to Australia....but because they took Longer to get back...Aus saw what was happening in the US and quarantined all the returning Troop Carriers a mile off shore..so Aus avoided the Worst of it coming back from Europe...saved the Mass infection.
Like they Seem to have done this time around too.....
