The document provides information about rabies including its definition, causes, transmission, symptoms, diagnosis, treatment and prevention. It defines rabies as a viral disease affecting the nervous system that is fatal if not treated. The rabies virus is transmitted via saliva, usually through animal bites. Symptoms start with fever and pain at the bite site then progress to neurological symptoms. Diagnosis involves biopsy of skin or antibody tests. Post-exposure prophylaxis within 7 days of exposure can prevent onset of disease. Vaccination and avoiding contact with wild animals are key prevention methods.
