Rabies has a long history of association with dogs. The first written record of rabies is in the Codex of Eshnunna (c. 1930 BC), which dictates that the owner of a dog showing symptoms of rabies should take preventive measure against bites. If a person was bitten by a rabid dog and later died, the owner was fined heavily.
Opossums are not considered dangerous to humans. [57] Though their open-mouth hiss when frightened is often mistaken as rabid behavior, opossums are naturally resistant to rabies due to their low body temperature. Opossums can however host parasites and carry diseases such as tuberculosis, leptospirosis, and tularemia, among others. [58]
An opossum may also use its tail as a brace and a fifth limb when climbing. The tail is occasionally used as a grip to carry bunches of leaves or bedding materials to the nest. [43] A mother will sometimes carry her young upon her back, where they will cling tightly even when she is climbing or running.

Furthermore, there was almost not english presence in Virginia before ...
