Viral diseases of man is the result of exposure to the organism of the smallest forms of life-viruses.

Viruses and viral diseases - it is the carriers of genetic information-the molecule of nucleic acid surrounded by a dense protective shell of proteins. Outside cells, viruses do not show signs of life and behave as particles of organic polymers. Simple in structure, do not have cell structure, pathogens can live only in living cells of the human body, animals, plants and in chick embryo fibroblasts. Invading cells of the human body, the virus begins to actively feed the contents of the cells, and gives it a quick death.

Viral human diseases share epidemiological characteristics zooantroponoznyh transmitted to humans from animals, and anthroponosis that can get sick. The main ways in which a viral infection transmitted to humans are:

- food route - ingestion of contaminated food and water transmitted viral hepatitis a And E;

through blood or bodily fluids transferring fragile virus that quickly destroyed in the environment. It is the rabies virus, hepatitis b, HIV etc. Transmission occurs during unprotected sex, when working with infected surgical instruments, and transplacental from mother to fetus of the child;

- transmitted by respiratory viral infections of influenza, mumps and varicella. This path is the most dangerous, as with air viruses are carried to a considerable distance, and is able to cause epidemics.

Each of the viruses in humans are the target organs that are more suitable for development of a particular viral infection.

Viral diseases, their clinical development can be divided into acute and chronic.

The Disease in the acute form occurs with a rise in temperature, pain in muscles and joints, weakness and changes in the blood. The examination of the patient revealed the symptoms of a local character - lose areas of the brain, liver and mucosa of the respiratory tract. Acute diseases are easily treated with medication. Correct and timely treatment of the patient will prevent the transition of the disease into a chronic form.

Another picture of the disease in the chronic form of viral infection. The disease usually goes unnoticed, viral human disease of this nature is very difficult to treat and can last for a long time, which leads to functional changes in the internal organs.

To dangerous infections applies latent infection that is a long time to be present in the patient in the absence of symptoms of viral diseases. It is this kind of infection can become active and go into an acute form by any pressure internal or external factor, such as reduced immunity or hypothermia.

The location of the infection can be local and generalized.

Viral diseases of man are of a local character, if the virus replicates at the site of lesion and infection is not posted on the body. Generalized infection, after initial propagation at the site of entry, then penetrate into the blood and carried by blood flow to various organs.
