Endemictyphus (also called "flea-borne typhus" and "murine typhus") is caused by Rickettsia typhi, transmitted by fleas infesting rats, and, less often, Rickettsia felis, transmitted by fleas carried by cats or possums.
Epidemic typhus is one of the strongest candidates for the cause of this disease outbreak, supported by both medical and scholarly opinions.
