Advice 1: What is encephalitis

Encephalitis is an infectious inflammatory disease of the brain. It can develop by direct penetration of the virus in brain tissue or occur as a complication of influenza, scarlet fever, chicken pox, measles, food poisoning and injuries of the skull. Encephalitis klassificeret by types depending on the causes. But since it is not always possible to install, start also from the characteristics of the disease.
What is encephalitis

Inflammatory process with encephalitis may be localized in the cortex of the brain, its membranes, subcortical nodes, the medulla oblongata. Sometimes it spreads to the spinal cord. The nature of the inflammation is purulent and non-purulent. This affects both the General and local symptoms of the disease.

There are several types of encephalitis: tick-borne (spring-summer), Economo (lethargic or sleepy), Japanese (mosquito), herpes, measles, flu, infectious, vetrenny.

Tick-borne encephalitis is also known as taiga or the spring and summer. His vectors are ixodid ticks, the peak of activity which occurs in the late spring, summer and persists until October. Begins abruptly, with sudden fever, painful headaches, poor sleep, vomiting, disturbances of consciousness. Outwardly to assume the tick-borne encephalitis by redness of the face, conjunctiva, sclera, neck and upper chest. In the meningeal form of encephalitis there is the tension of the occipital muscles. After the acute period (6-10 days), you may notice residual effects in the form of paralysis. Also the possible transition of the disease into a chronic form, characterized by changes in brain tissue, formation of adhesions and cysts.

Japanese encephalitis known as the mosquito as a carrier are certain types of mosquitoes. Infection occurs by the bite. Manifested by increased muscle tone, a characteristic feature is the bent arms and extended legs, decreased vision, drowsiness, weakness. There are often convulsions and paralysis and impaired swallowing and breathing and trembling of the hands (tremor). The disease is acute and in most cases has a lethal outcome. Recovered can persist paralysis and mental disorders.

Economo encephalitis, or sleeping sickness, sleepy transmitted from person to person by airborne droplets. Manifested by drowsiness, and patients may sleep in any position: standing, sitting. However, it may be insomnia. In addition, develops paralysis of the oculomotor nerve. At a favorable outcome of the disease often becomes chronic and manifests with symptoms of Parkinson's disease.

Encephalitis caused by measles, herpes, chicken pox, influenza and other infections is secondary. Most often, the symptoms of any of these diseases join meningeal signs: paresis, paralysis, muscle tension of neck, hand tremor, loss of coordination, mental disorders, photophobia, seizures, and others. However, they also may occur at the stage of recovery. The disease is serious and even at a favorable outcome is often residual effects in the form of paralysis, paralysis and nervous disorders. But at the time begun treatment recovery occurs simultaneously with the primary disease.

Advice 2: How is encephalitis

Encephalitis is a viral disease that is transmitted to animals and humans through the bites of Ixodes ticks. The most terrible symptom of encephalitis is inflammation of the brain.

Tick-borne encephalitis or taiga encephalitis is an acute neyrovirushnykh infection that is transmitted by ticks. Characterized by sudden onset, pronounced fever and various lesions of the Central nervous system. The disease is known in two geographical variants – Eastern and Western encephalitis.
The causative agent of tick-borne encephalitis refers to the arboviruses of group B. Among lab animals most sensitive to this virus to white mice, cotton rats, hamsters, monkeys, and domestic animals sheep, goats, pigs, horses.
The virus is very sensitive to most common disinfectants and to the action of high temperatures, but in the dried state may persist for many months or even several years.
Vector-borne encephalitis, ixodic ticks. They also serve as a reservoir in which the pathogen resides. Infection even nutritional way, for example, by eating raw milk. For encephalitis is characterized by seasonality. The first cases usually appear in April, then their number increases and reaches maximum values in may-June. But during the July-October may experience some isolated cases of infection with encephalitis.
With regard to susceptibility to infected with encephalitis can all age group people. But most of all vulnerable to infection persons who by the nature of the profession associated with the forest or frequenting the forest, such as mushroom pickers.
There are two ways of Contracting encephalitis – vector-borne and alimentary. When vector-borne route of infection entry is the skin, and when the alimentary mucous membranes of the gastrointestinal tract. After penetration under the skin comes the latent period of the disease when the virus multiplies in the subcutaneous tissue, but due to dissemination may be detected in the lymph nodes, gastrointestinal tract or spleen. The next stage is the neural, during which the virus multiplies in the Central nervous system. Affects hard and soft meninges.
The incubation period for encephalitis varies from 10 to 14 days. The beginning is manifested by weakness, headache and numbness in half of face or body, mental disorders. Also, there is a fever with a temperature rise to 39-40°, 5 degrees. May be vomiting, excruciating joint pain and photophobia. CNS can be observed paresthesia, paresis of the limbs, convulsions, double vision and even loss of consciousness.
Hospitalized with encephalitis mandatory. The condition statement is a complete recovery. Special treatment to horse gamma globulin, which is administered intramuscularly in a dosage of up to 6 ml. it is Also possible the use of human hyperimmune Gama-globulin.
