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. [6] The World Health Organization (WHO) reports that dogs are the main source of human rabies deaths, contributing up to 99% of all transmissions of the disease to humans. [7]
3D still showing rabies virus structure. Rhabdoviruses have helical symmetry, so their infectious particles are approximately cylindrical in shape. 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.

Mammals, including humans, can serve as natural hosts. [3] [4] The genus Lyssavirus includes the causative agent (rabies virus) of rabies. [5]
Negri was convinced the inclusions were a parasitic protozoon and the etiologic agent of rabies. Later that same year, however, Paul Remlinger and Rifat-Bey Frasheri in Constantinople and, separately, Alfonso di Vestea in Naples showed that the etiologic agent of rabies is a filterable virus. Negri continued until 1909 to try to prove that the ...
