Rabiology involves rabiologic surgery as well as vaccinations against rabies. Rabies is a severe viral infectious disease, which can survive in the environment within the infected animals's saliva. Rabies virus might enter the human organism through a wound or mucosal membrane. Rabies causes inflammation in the central and peripheral nervous system. This is manifested by respiratory and esophageal muscle contractions, increased salivation. At this point, it's impossible to cure the disease. When a person is bitten by a dog or a cat, he/she should receive the prophylactic treatment on the same day, as well as on the third and seventh days. If the animal, which was in contact with the patient, survives for more than 14 days, anti-rabies prophylaxis can be stopped. If the animal is dead or lost, the treatment continues on the 14th and 28th days. This is already a therapeutic intervention (as opposed to prophylaxis). If the skin is damaged, anti-rabies prophylaxis should be accompanied by anti-tetanus vaccine.
