DownloadWe’re pretty solid on germ theory at this point.
The idea that many diseases are caused
and spread by pathogens too small to seen
has been locked in since the mid 19th century.
But that wasn’t the first time people came up with those ideas.
Physicians around the world had been theorizing
about the spread of infectious disease through invisible particles
as early as the 9th century.
That’s one thousand years earlier.
These scholars did everything they could to limit the spread of infection
and understand how it worked.
But if we had the basis for germ theory …
by all accounts a correct idea …
why did it take so long for it to actually take root?
Well, because right ideas don’t always win – not right away.
And sometimes wrong ideas can be pretty convincing.
