The only disease on this list that actually existed, the Bubonic Plague ravaged 14th century Europe, reaching pandemic proportions through the 19th century.

Or an easier way is just to imagine your very worst nightmare, then multiply that times 2,000. That’s what “The Signal” does, making it easily the most horrifying movie disease of all time.
