What is hydrophobia (rage) dangerous by?
danger of rage (hydrophobia) were mentioned still by Democritus in the fifth century B.C. Effective treatment at the developed hydrophobia it is not developed still. In literature only isolated cases when by means of methods of intensive therapy it was possible to rescue the diseased are described. At the same time according to WHO data (World Health Organization) from hydrophobia tens of thousands of people annually perish. In what business?
Rage is registered almost in all countries. All mammals, birds and the person are susceptible to an illness. As a rule, the virus of rage is transmitted with saliva at stings. The fact that it appears in saliva of the infected animals for several days (for example, at dogs in 8 - 10 days) before emergence of the first clinical symptoms of a disease is especially dangerous.
… You play with a little lap dog (or a kitty), she caresses, licks to you hands when you treat her with sugar cubes, and looks absolutely healthy. And then, in few weeks, it becomes clear that the lap dog (cat) died. Inconsolable owners of a lap dog (cat) brought it to veterinary clinic, there in cells of a brain of this charming creation found Babesh`s little bodies - Negri that is a reliable symptom of rage. What to do in that case? To hope that two weeks ago integuments of your hands had no cracks and grazes? Or to complete a course of antirabichesky vaccination what is very painful? Everyone solves. It is almost like Russian roulette only prolonged: the incubatory period at rage - from 10 to 90 days (sometimes till one year), on average - forty days.
Statistically at stings from 3 to 50 percent of people get sick with obviously mad animals (on average 15%). Incidence depends on degree of natural resilience of an organism of this or that person, virulence of a virus, its dose and a source of infection. For the person the greatest danger is constituted by stings of wolves: there is a considerable travmatization of fabrics, with saliva the high dose of a virus is brought. And in general, animals on extent of reduction of danger of stings it is possible to arrange in the following order: a wolf - a fox - a cat - a dog - cattle.
Infection with rage can occur also without damage of integuments if the infected saliva gets on a mucous membrane, for example, on an eye conjunctiva. Transfer of a virus of rage vozdushno - is possible a drop way. Experiment (American) was following. Cages with healthy foxes placed in caves where bats - vampires among whom the virus circulated lived. In cages from a close-meshed grid bats could not get, that is direct contact was impossible. However after some time of a fox nevertheless ached with rage.
Calms only the fact that the virus of hydrophobia is unstable in external environment. Heating to 55 - 60 degrees neutralizes it within an hour, at 100 degrees he perishes instantly. Disinfectants (for example, 5% solution of formalin) kill a virus within several minutes.
If to speak about prevention, then, in - the first, it is inoculations an antirabichesky vaccine of the people bitten, scratched or obslyunyonny obviously mad animals and also who animal fell, killed or who disappeared within two weeks after a sting. Inoculations are actual when are begun in the first 14 days from the infection moment. In - the second, it is necessary to impart from rage and the pets: beginning from cats and finishing horses.
At the same time it is worth mentioning that vaccination of people antirabichesky vaccines sometimes causes heavy neurologic frustration. The vaccine offered Fermi in 1908 as it contains a quantity of a live virulent virus is most dangerous in this regard.
However, in medical literature several cases of recovery of people at the developed hydrophobia are described. Methods of intensive therapy in the conditions of intensive care unit were applied. The hope is always.
