[Monsters Inc] What made the monster world believe that kids were hazardous?

So, monsters inc (the company) went into full production in 1895. Which means we know at least one thing that happened shortly after they began exploring the human world in earnest.

The Spanish Flu.

One of the deadliest pandemics in human history, infecting a third of humanity and killing 60 million people.- and that was humans who were used to flu viruses. Imagine how devastating it would have been for a species that had no prior experience.

As scare workers came back dead from being around humans? Well. "humans are deadly to be around" isn't a wildly unreasonable conclusion for a panicked society to reach. It should be noted that it seems the higher ups are aware they aren't dangerous- they know its was a pandemic now over- but the common perception is harder to erase.
