Diphtheria

Reading "The Cruelest Miles:The Heroic Story of Dogs and Men in a Race Against an Epidemic"
and it is very interesting. Diphtheria sounds like something out of science fiction, "The membrane that forms over the tonsils can also move deeper into the throat and block the airway." Yuck.

Missouri's Governor's mansion is haunted by a girl taken by Diphtheria. The Mark Twain cave is also rather gruesome.

Diphtheria heroes were sled dogs but also horses.
