Rabies refers to a group of diseases, pathogens which are in the process of evolution adapted to parasitism in the body. Suffer all warm-blooded animals. The main source and
reservoir of the virus are wild carnivores (foxes and wolves) and
Pets (dogs, cats) are allowed. Infection of animals and humans
It comes in contact with saliva on broken skin or mucous membranes
shell and bites rabid animals. The causative agent of rabies
accumulates and is excreted through the salivary gland not only during
disease, but also in the incubation period of 24-72 hours, and sometimes for 7-8 days
until the first signs of the disease.
damaged skin and mucous membranes. The wound along nerve virus
fibers penetrate into the central nervous system, and concentrated in
certain parts of the brain and spinal cord, causing them to defeat.
Selectively affects the nerve cells of the hippocampus, medulla oblongata,
cranial nerves, the lumbar portion of the spinal cord and major components of autonomic plexus. From the central nervous system by the virus spreads
nerve trunks throughout the body, including in the salivary gland.
As a result, virus propagation occur inflammatory and necrotic changes in the nervous system.
Symptoms of rabies
The incubation period lasts from 8 to 90
days, at least 1 year, more often 20-30 days. Short incubation notes

The disease begins with the precursors. First, there is
anxiety, depression, desire to be alone, sick masters
