Opossums are not considered dangerous to humans. [56] 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. [57]
Most cases of humans contracting rabies from infected animals are in developing nations. In 2010, an estimated 26,000 people died from the disease, down from 54,000 in 1990.

They are characterized by an extremely broad host spectrum ranging from plants [citation needed] to insects [citation needed] and mammals; human-infecting viruses more commonly have icosahedral symmetry and take shapes approximating regular polyhedra.
