A virus is a unique microscopic organism that is coated with lipid, glycoprotein, and contain the genetic material like rna or DNA. Viruses cannot reproduce without host cells. After coming in contact with the host cells, they release the genetic protein, and seize the host functions. As a result, the host cell is infected, and now it reproduces the viral protein rather than its original product. Viruses are spread in two ways. First, it spreads vertically, that is from mother to child, and secondly it spreads horizontally from person to person. Few viruses spreads from a simple contact, exchanges of saliva, coughing or sneezing, sexual contact, while other spreads from fecal-oral route via polluted food or water.
Viruses can cause several disease like, small pox, the common cold, measles, chiken pox, hepatitis, influenza, human papiloma virus, shingles, polio, ebola, hanta fever, hiv, cold sores, SARS, dengue, Epstein- barr virus, and few cancer.
Treatment of viral infection
Unlike bacterial infection, which can be treated with the antibiotics, viral infection can only be cured with the vaccination, or the antiviral drugs. Vaccinations are a most popular and are one of the cheapest ways of treating viruses. It restricts the complications beforehand. Many times we have natural immunity of viral infections, but in few cases, for instance if you talk about polio, HIV, hepatitis, cancer, one needs proper treatment and vaccinations. Currently, you may find many vaccinations related to viral ailments. This is a result that there is subsequent decrease in the figure of polio, measles, influenza, and other chronic disease. During the procedure, of vaccination a weakened form of the virus (live-attenuated viruses),is given to the patients as a form of antigens. However, at times, they fall in risk, of getting through the actual disease, making the immune system extremely weak. The antiviral drugs have been very lucrative, in the case of patients suffering from aids. These drugs do not destroy the pathogen rather it withhold their development. In comparison to vaccination, the antiviral drugs are safer to use.
Combat from viruses
People, who have a very good immunity, can fight with the minor viral infections easily. Therefore, first tip for you is eating a lot fruit, vegetables, vitamin C products, and a regular exercise. Our body automatically detects viral infections. When any virus is noticed with our immune system, the body starts responding in a generic way. This process is called as RNA inference. This crucial mechanism combats with viruses, by degrading its genetic material, and enables the cell to survive the infection. Our immune system actively produces the antibodies, which combines with virus, and help it to neutralize. To add, the body T cells are sent to shoot them off. However, almost ninety percent of the viruses are well handled by the body’s immune system, while in case of few viruses, for instance, HIV, is able to evade the immune system through different techniques. Neurotropic viruses are also smart enough in making our immune system weak.
