1. Characteristics of Rabies
1.1 Definition of Rabies
Rabies is a viral disease that affects the nervous system, particularly the brain, and is usually transmitted through the bite of an infected animal. It belongs to the family Rhabdoviridae and the genus Lyssavirus. Rabies is typically fatal if not treated promptly and poses a significant public health concern worldwide.
1.2 Transmission of Rabies
Rabies is primarily transmitted through the saliva of an infected animal, often through a bite or scratch. The virus enters the body through broken skin or mucous membranes, such as the eyes or mouth. It then travels to the central nervous system, where it replicates and spreads, causing inflammation and damage to the brain.
1.3 Symptoms of Rabies
The symptoms of rabies can vary depending on the stage of the disease. The initial symptoms may include fever, headache, and general malaise. As the disease progresses, more specific symptoms may develop, such as aggressive behavior, confusion, hallucinations, and difficulty swallowing. In the later stages, paralysis and respiratory failure can occur.
