Rabies is caused by a virus that attacks the central nervous system. The virus is normally introduced by an animal bite that breaks the surface of the skin. Since the virus is not motile, how does it travel to the central nervous system?
What will be an ideal response?
When the animal bite punctures the skin, some nerve receptors are physically damaged. The virus gains entrance to the neuron through these damaged axons. Retrograde axonal transport moves the virus toward the cell body and toward the central nervous system, where it can reproduce and spread.
