Viral Infection Meaning And Types

The viral infection is one of the patterns of infectious diseases caused by viruses, which take the form of capsular inside to contain genetic material from bacteria and is characterized by small size, enabling it to invade healthy living cells and be used as an environment to breed and multiply their numbers and the elimination of host cells, causing the appearance of symptoms of the disease.

Viral Infection Meaning And Types
It characterized by difficulty to treat viral infections, where believes the virus that causes the infection protection for himself inside the cells of the body away from the influence of different drug treatments, also features to target specific cells in the body and not others.

Most viral illnesses do not respond to treatment with antibiotics, but there are antiviral experimental materials (Antiviral)and that can slow down the progress of the disease and sometimes even addressed.

Viruses are a group of microorganisms that have been classified into nearly 4,000 items (estimates indicate the existence of 400,000 Class). The size of these viruses is less than 0.2 micro meter and can be seen by an electron microscope.

The general definition of a virus

The general definition of a virus is that it was capable of encryption (coding self) (enciphered to itself) and the need for mechanisms to double the storage itself.
Viruses are parasites absolute, multiply by penetration into the living cell, which controls the construction machinery (synthesis – synthesis) to reproduce itself. Virus graduated from the cell by budding (budding) continued for a few viruses or by dissolving the cell membrane and the deployment of a large number (tens even hundreds) of viruses around.

These viruses are built of membrane protein (and sometimes greasy) and genetic material (RNA skim oxygen – DNA) or RNA (RNA). There are special viruses to plants, animals and even bacteria. It has been identified hundreds of varieties pathogens in the human body. For example: Flu viruses, colds, polio, smallpox and herpes (herpes).
We have been developing vaccines effective for the majority of circulating viruses. In some cases (flu-like, for example) regarding the efficacy of vaccination suitability of the changes that occur in the virus from another year of building.
In certain cases, there is difficulty in the production of an appropriate vaccine, example is the AIDS virus (HIV), but efforts are continuing to find a suitable vaccine.
