Rabies, also known as rabid dog disease and hydrophobia. It is a direct contact infection caused by the rabies virus in humans and all warm-blooded animals (humans, dogs, cats, etc.). Once a person is bitten by a dog containing the rabies virus, there is a 30-70% chance of infection, and once the disease develops its mortality rate is 100%. Therefore, dogs that are pets must be immunized against rabies. The clinical manifestations of a dog with rabies are extreme excitement, frenzy, salivation and loss of consciousness, and eventually death by general paralysis. Rabies, or rabies, also known as hydrophobia, is an acute viral infection that attacks the central nervous system and can infect all warm-blooded animals, including humans. It is mostly obtained from the bite of an infected animal. It is generally thought to be transmitted from the bite of a rabid dog with white foam coming out of its mouth, but in fact cats, ferrets, raccoons, skunks, foxes or bats can also be affected and infected. The sick animal often becomes so savage that the virus in the saliva enters the next patient from the bite wound. The transmission of rabies from one person to another is extremely rare, and most human patients with rabies die of the disease, with one case of recovery in 1971. 2004 saw the death of an undiagnosed rabies patient in the United States who donated his internal organs, and the three people who received the donations died of rabies.
