Detailed explanation-1: -Rabies virus belongs to the order Mononegavirales, viruses with a nonsegmented, negative-stranded RNA genomes. Within this group, viruses with a distinct “bullet” shape are classified in the Rhabdoviridae family, which includes at least three genera of animal viruses, Lyssavirus, Ephemerovirus, and Vesiculovirus.
Detailed explanation-2: -Those viruses move on and attach to other nerve cells until eventually they get to the brain. There the virus can cause the brain to swell, and the person with rabies may go into a coma and die.
Detailed explanation-3: -Rabies is an infectious disease that spreads from animals to humans. The rabies virus causes the disease by infecting nerves in animals and people. The rabies virus travels to the brain (through nerves inside the brain), the virus reproduces, and then it travels back through the nerves to most parts of the body.
Detailed explanation-4: -Some viruses infect only neuronal populations such as rabies, polioviruses, and the arthropod-borne viruses, and some only infect selective neuron populations. Other viruses, such as herpes simplex virus, appear to infect neurons and glial populations with little selectivity.
