Rabies affects which body system?

Rabies affects which body system?

• A. Nervous
• B. Respiratory
• C. Cardiovascular
• D. Digestive

Answer: (A)

Rabies is a neurotropic virus that primarily targets the nervous system. After entering through a bite, the virus travels along peripheral nerves to the brain and spinal cord, causing inflammation of the CNS (encephalitis) and widespread neural dysfunction. This CNS involvement leads to the characteristic neurologic signs—behavior changes, agitation or aggression, difficulty swallowing, and paralysis—and, if untreated, death. While other body systems can show secondary effects, the nervous system is the main system affected, which is why it’s the correct choice.
