How can Rabies still exist and be as prevalent as it is, if it's lethality is 99.99% and it's disease cycle is relatively short?

Because rabies can infect a lot of different animal hosts, many of which can live a long time or indefinitely after being infected. These are known as reservoir hosts because they provide a stable source for infections of more susceptible hosts. Reservoir hosts for rabies generally include Carnivoran mammals (raccoons, skunks, canines) and bats.

Human-to-human transmission of rabies is incredibly rare. Almost all infections come from animals, either directly from a reservoir host or from another animal that was recently infected by a reservoir host.
