Meaning of Virus

what is the Virus:

Virus is an obligatory intracellular parasite, of small size, consisting of nucleic acid and protein, which is the cause of many diseases such as: influenza, ebola, human papillomavirus, AIDS (HIV), among others. The word virus comes from the latin “virus” which means “toxin” or “venom”.

Viruses are formed by: the genetic material that carries hereditary information good either DNA or RNA, capsid which is a protein coat that protects the genes and a viral envelope or lipid bilayer surrounding them when they are out of the cell.

Viruses cells require guests to be able to reproduce inside cells can get amino acids, Ribosomes and other substances that allow the multiplication of new viruses, once the virus is inside the cell begins to interfere with the normal operation of them causing diseases mentioned above, among others many. The viral replication process can take hours as days, it all depends on the virus.

In reference to the above, the medical studies indicate that vaccines and antivirals are the measures to deal with viral diseases and resist infection.

Meaning of Virus 1

Virology is the branch of Microbiology or medicine which is responsible for studying the behavior of the virus, its structure, classification, evolution, techniques for their isolation, among others. Is also the generic name of the diseases caused by pathogenic viruses viruses.

Currently, medicine is with a hard work in the Studio of the ebola virus that is part of the virus of the Filoviridae family and genus Filovirus, the disease arises from contact with blood or body fluids of infected animals and, 3 days or 2 weeks of contracting the disease begins to appear as symptoms: high fever , headache, muscle aches, sore throat, which is followed by nausea, vomiting, diarrhea, together to liver and kidney failure and sometimes internal or external bleeding. While scientists are doing research in order to achieve healing and prevention of the disease, currently, there is no vaccine to prevent this virus or specific treatment to cure him, the only help received ill Ebola patient is oral rehydration therapy and intravenous fluids.

Computer virus

computer viruses are a computer program which aims to disrupt the functioning of the computer regardless of the will of the user. Some viruses only replicate, others can cause serious damage affecting systems, in the latter case, the virus code is hosted in the computer’s RAM memory and take control of basic services of the operating system, infecting way back, to the executable files.

Meaning of Virus 2

However, more famous or common viruses are: Trojans that steal information allowing the external user control or alter the device, worms and time-bombs.

Antivirus are software created by businesses with the aim of eliminating the virus in infected computers.

Viruses and bacteria

Occasionally, individuals use the terms virus and bacteria as synonyms, which is normal since these microorganisms have similarity be disease-causing, however, they have different characteristics.

Viruses are acellular organisms, i.e., does not have cells, and to reproduce they need to live in the host cells, they have a size of 20 to 500 Millimicrons of diameters which can be detected by electron microscopy, at the same time, the bacteria are unicellular microorganisms, thus, are living beings that possess cells, have a diameter between 0.6 and 1 micrometer, i.e. they are up to 100 times larger than viruses, in a way that can be seen by optical microscope. Viruses have a simple structure that consists only of genome, covered by a protein envelope and capsid, is why do not breathe, do not move or grow, on the other hand, bacteria have a cell wall that is real, an internal structure and this wall include the cytoplasm, Ribosomes and the bacterial genome, a structure that allows them to grow and reproduce.

With respect to cure, the virus as it was said above is based on preventive and antivirals, vaccines bacteria through injection of antibiotics or take.

Viral marketing

Meaning of Virus 3

Viral marketing is a set of techniques that make use of internet media such as social networks, blogs, emails, youtube, among others, to increase sales of products and services as well as improving the positioning of a brand through the dissemination of the message viral, or exponential-shaped.
