“Maybe the Spanish Flu was really a Cornavirus.”
I think they’ve actually recovered the spanish flu virus from cadavers of victims, and it IS an influenza virus ... and if i remember correctly what has medical professionals freaked out about another killer flu virus coming along like that one is that they can’t figure out exactly what makes the spanish flu virus such a killer by looking at its structure and RNA genome ...
I think the Swine Flu of 2009-2010 was a variant of the Spanish Flu.
