Symptoms of rabies in humans

Rabies is a viral infection,which is distributed among mammals, particularly among domestic animals and some predators and transmitted from them to humans, through bite and saliva. This disease was known to people back in ancient times. Many historical sources mention rabies, which is transmitted to people from infected animals. The causative agent of the disease is a neurotropic virus containing ribonucleic acid.

This disease is characterized by a contact methodinfection. The causative agent enters the wound through an animal sting or through a damaged skin. It should be borne in mind that not always bitten become infected with rabies. This is due to the fact that the virus itself can not be present in the saliva of the carrier during the latent period of the disease. The incubation period of rabies is approximately 60 days, but there are cases when it is 12 months. In humans, the shortest period is observed with the bite of the upper limbs and body parts, and the longest with the bite of the lower extremities.

The virus that got into the human body through a bite,penetrates the brain and spinal cord, multiplies and causes inflammation. Along the nerve pathways, he moves to various organs of the person, also getting into the salivary glands, thus infecting the saliva. Further, the disease causes degeneration of the nerve cells of the brain, which provokes various disorders of activity, including death from paralysis of the respiratory musculature.

Symptoms of rabies in humans are characterized bycramps of the respiratory muscles, which are replaced by paralysis and eventually lead to death. Convulsions contribute to the slightest external stimuli, for example, light, noise, and so on. If to say, what symptoms of rabies in a person are specific, then we can talk about rabies, which manifests itself in the spasm of the larynx at the sight of water or its sound. Patients become aggressive, they have delusions and hallucinations. The stage of excitation is replaced by the stage of paralysis, which leads to a lethal outcome.

In the event that a vaccination against rabies was not done to a person, the disease always ends in death. If the symptoms of rabies have already manifested in man, there is no chance of salvation.

To combat the disease, rabies vaccine is used, but it is effective only in the initial stages, for several days after the victim was bitten.

At the onset of the disease, the symptoms of rabies in humansmanifested in the form of depression, high fever and burning, itching or other unpleasant sensations at the site of the bite. After this, other symptoms appear - shortness of breath, anxiety and anxiety, aversion to fluids, convulsive seizures. In the final stage of the disease, paralysis of various organs and parts of the body is observed. In exceptional cases, rabies is initially manifested in a paralytic form.

If we talk about the stages of the flight, then they are divided into three parts: the initial, the stage of excitation and paralytic.

During the first stage, the temperature rises,general health deteriorates. There are severe pain in the head and muscles. Also, many infected have dry mouth and vomiting. The bite site unpleasantly burns, itching appears. Other manifestations are possible, for example, hallucinations, as well as loss of sleep, but they are rare.

During the second stage, the patient appears the main sign of rabies - hydrophobia, hydrophobia. Also the patient shows excitement, aggression, cramps of extremities.

At the third stage, a paralysis of variousorgans, in particular the ocular muscles and lower extremities, but ends with paralysis of the respiratory organs, which, in fact, causes the death of a person. The duration of the course of rabies is no more than 15 days.
