Human-to-Human Transmission

Humans are mammals. Therefore, theoretically, human-to-human rabies transmission is possible. However, there are no laboratory-tested cases to confirm that this has actually happened. But there have been 8 confirmed cases of death due to human-to-human rabies transmissions resulting from cornea transplants. Because these deaths were medically confirmed, there are now improved guidelines to screen organ donors for the rabies virus.

Dracula

The following passage is from Bram Stoker's classic tale of horror, Dracula, written in 1897: "Dr. Vincent took the bandage from its throat, and showed us the punctures. There was no mistaking the similarity to those which had been on Lucy's throat. They were smaller, and the edges looked
fresher; that was all. We asked Vincent to what he attributed them, and he replied that it must have been the bite of some animal…he was inclined to think it was one of the bats which are so numerous..."

Many film versions of Stoker's book have made Dracula's long black cape and habit of prowling around at night in search of victims common knowledge. Even little kids have their own educational version of Dracula—The Count on Sesame Street. But these days this paragraph from Bram Stoker's book has an eerie ring of truth.

Of the 32 human rabies cases reported between 1990 and 2000, 24 were caused by contact with bats, making bats a major concern when it comes to rabies and humans. Because bat teeth are small, bite marks are small as well. And bat bites don't hurt as much as a bite from other, bigger animals, so they have been known to go undetected.
