Spread, Treatments and Diseases caused by viruses such as Yellow Fever AND Chickenpox

Many times we wonder, because we sick or because our children acquire a disease like chickenpox, yellow fever, any flu or diarrhea, unfortunately there viruses that spread in the environment or are broadcast with just talking to a person and without realizing we contaminate with this virus.

In this article explains the appearance of the virus and its way to spread, this can help us to avoid get according to the type of virus that exist, parents may take the necessary measures to protect their children and avoid getting illness that even can be fatal as hepatitis.

The virus (poison in latin) are parasites intracellular submicroscopic, composed of RNA or by deoxyribonucleic acid (DNA) within a protection called the deck or viral capsid, which in turn, is composed of fragments of proteins called capsómeros.

Some have an extra layer called wrapper. The viral particle complete called virion. The virus are parasites intracellular obliged, only are replicated in cells with active metabolism. Outside of them are reduced to macromolecules inert.

Physical Appearance

The size and shape of the virus is highly variable. There are two groups basic structural: isometric, with form of rod or elongated, other viruses have the form of ovals sharp or bricks with the round corners and virus complex, with head and tail.

The virus are found in all materials and in the environment of the land from the sun until the air and water. In any place where cells to which they can infect. The virus have evolved and can infect any form of life as animals, plants and fungi.

Spread

Many viruses get into the human body through the mucous membranes wet lining the respiratory tract, eyes, the intestines or the reproductive system. The infection occurs through the body fluids of an infected person or through the air in droplets from coughing or sneezing.

The viruses that cause diarrhea, spread by the mouth-bowel movements. In other cases, the spread is carried out through the insect bites, as in the case of yellow fever. Within the body, the virus can spread from one place to another through blood vessels and arteries or pathways that carry fluids between tissues, and even through the nerve cells.

Once you have invaded the agency and caused a disease, the immune system can combat completely some viruses. The viral diseases can be endemic (inherent in an area), which affect the susceptible people, or epidemic, which appear in large waves and attack a large part of the population.

An example of epidemic is the emergence of the flu throughout the world, almost always, once a year. The virus of chickenpox and herpes simplex virus may remain inactive in the interior of the human body cells and cause more of an episode of the disease, even years after infection.

The Advancement of Medical Science

The virus represent a major challenge for the medical science in its fight against infectious diseases. Many viruses cause human diseases of great importance and diversity. Among the viral diseases is the common cold, affects millions of people every year. Other diseases have serious consequences such as: rabies, hemorrhagic fevers, encephalitis, tetanus, polio and yellow fever.

Most of the virus causing diseases that cause only an intense discomfort, provided that the patient he was not serious complications. Some of these are the influenza, measles, mumps, the fever with hot flashes (herpes simplex), the chickenpox, herpes (such as the shingles), respiratory diseases, the acute diarrhea, warts and hepatitis.

At present, is still discovering virus responsible for human diseases. The majority can be isolated and identified with the current methods of laboratory, although the process usually takes several days.

Treatments For Diseases

The treatments exist against viral infections tend not to be entirely satisfactory, since most of the drugs that destroy the virus also affect the cells in other reproduced. The only effective means to prevent the viral infections is the use of vaccines. Have been developed many vaccines against human viruses and other animals. Among the infections which suffer from the people will include the measles, rubella, polio and influenza.

Vaccine: Method of Immunization

The immunization with a vaccine antiviral stimulates the mechanism auto immune of the agency, which produces antibodies that will protect when you come back to contact with the same virus. The vaccines always contain viruses altered so that they cannot cause the disease.

As has been indicated there are many diseases caused by viruses, that we strongly recommend be prepared against the virus, one of the ways is to get vaccinated and the other is maintaining a good hygiene. Avoid being close to the sick people to avoid the contagion produced by the virus.
