Re: 1918 Spanish Flu a Biological Warfare Agent?
Biological warfare was even used in the medieval era. The corpses of diseased animals and humans were catapulted over castle walls during sieges in the hope of infecting the occupants within.
In 1918 people were aware of the existence of microbes and had a fair idea of how they worked.
It is not implausible that in 1918 it had been observed that an often deadly disease sometimes caused birds to fall out of the sky and in order to make the disease transmissible to man they had taken the bird ‘flu and given it to pigs? This is how scientists today believe Spanish ‘Flu came about, that an avian ‘flu was given to swine and then finally to man.
