Might be a myth..might not

No specific anti-viral therapies were available during the 1918 flu. That’s still largely true today, where most medical care for the flu aims to support patients, rather than cure them.
One hypothesis suggests that many flu deaths could actually be attributed to aspirin poisoning. Medical authorities at the time recommended large doses of aspirin of up to 30 grams per day. Today, about four grams would be considered the maximum safe daily dose. Large doses of aspirin can lead to many of the pandemic’s symptoms, including bleeding.
However, death rates seem to have been equally high in some places in the world where aspirin was not so readily available, so the debate continues.
Interesting... Thanks for sharing.
