What Is a Viral Internet Message?
A virus is a tiny submicroscopic infective agent which replicates almost invisibly within the living tissues of an infected organism. Like a virus, it invades the host cell by causing a reaction which results in the programmed destruction or damage of the target structure. Viruses mainly infect all forms of living organisms, from plants and animals to micro organisms, such as bacteria and Archaea. Human cells are also prone to infection by viruses; hence, the term ‘virus-like’ on the symptoms list.
A virus may appear as a single celled viral infection, or as multiple infected cells in a particular microcosm. The viral particles, once implanted into a host cell’s framework, replicate themselves and multiply exponentially, eventually coating every surface of the target cell with viral RNA and encapsulating protein. These viral particles are carried by interferon molecules, which are part of the body’s immune system. When a person comes in contact with a virus, the immune system goes into attack mode, triggering massive action against all invading microorganisms.
The major effect of virus infections is on the human body’s cellular metabolism. They tend to kill off vital cells in the body, causing cancer. Some types of cancer are known to be associated with viral infections, like cervical cancer, leukemia and lymphoma. The major threat in the occurrence and development of cancer is associated with the uncontrolled multiplication of the virus. As with other forms of cancer, genetic changes occur rapidly during the development of cancer, compromising the future ability of the victim to fight the disease.
While not dangerous in themselves, a virus can produce symptoms which are highly uncomfortable or damaging to the human body. Common colds are brought on by virus infections, as well as fever, headache, cough, sore throat and general malaise. Many types of influenza viruses are known to cause death and serious illness through the development and spread of respiratory viruses. One example is the SARS virus, which was responsible for the current epidemic in China. The recent swine flu has also caused panic and widespread panic across the globe.
A virus can spread in a number of ways. It can be contracted from touching an infected object, like a piece of cut glass, or breathing in vapors, like when using a cigarette. Viruses can also be spread through insect bites and through direct contact with bodily fluids. In the case of a health virus like HIV, genital contact is actually required to pass on the infection. A virus which has been dormant for years can suddenly spring back to life, as shown recently with the SARS virus.
We’ve all heard the old saying, ‘Don’t judge a book by its cover.’ This saying holds true with many covers, including virus ads. Though it is easy to be turned off by an ugly virus ad, it is important to remember that viruses are a major problem in modern society. With the increase of technology, people have become more susceptible to diseases and infections. So is it just a cover that we’re using to scare people?
