The book wasn't very film-able, so the movie they made from it was quite different in approach.
I've also heard there's a non-fiction book about the "Spanish flu" outbreak that basically reads like a zombie film (e.g. one interesting tidbit, they call it the Spanish Flu because that is where the first reported cases were, but it didn't start there, the other countries just suppressed the information because they were at war)
It's only in the last 150 years that it gained scientific acceptance.
It took a while for the scientific community to accept that some diseases are caused by a lack of vitamins, for example.
Although we must be careful, in one of my more interesting jobs, building a full text database for Year Book Medical Publishers (a part of Time ... -Life? Time as in the LA Times back then), the leading article for the general book for that year was on the proof of gastrointestinal ulcer being caused by a bacteria. The editor of that entry figuratively smiled about "taking away another disease from" ... whichever specialists assigned it all to stress (which of course can predispose someone to getting an infection).
Or that the majority of the human body by cell count is actually composed of bacteria...
