The rabies virus causes hostility within its host because aggressive behavior (e.g. biting etc.) is crucial for the transmission of the pathogen due to the fact that the virus is primarily secreted within the saliva of its hosts, although it can be present within and therefore transmitted via other tissues as well (e.g. infected brain tissue coming into contact with the open wound of a host etc.). The rabies virus primarily affects the central nervous system of its host, involving both the brain and spinal cord, causing inflammation of the brain referred to as “encephalitis”, and triggering various other neurological symptoms which help aide propogation (e.g. aggression, confusion, hallucinations etc.). The rabies virus travels along nerves from the wound site of the infection to the brain, where it then replicates and causes inflammation. Once the rabies virus reaches the brain, it can spread rapidly throughout the body via the central nervous system, leading to severe neurological symptoms and death in 100% of cases if left untreated
