Captain Trips (first appeared in Night Shift)

Captain Trips, a killer virus, first appeared in the short story "Night Surf" - but it's better known as the devastating disease in The Stand which kills 99% of the world's population. Fun fact: the name comes from Jerry Garcia's nickname, because The Grateful Dead's extensive tours across America served for King as an analogy for the way the Captain Trips virus travelled across America.

Captain Trips is mentioned in the following books:

The Stand (Sep 1978)
