Viruses

Biological science in today’s society is threatening to our lives in different forms. One particular spread of infection is the, all too familiar, virus. The likelihood of a human viral outbreak is rather rare, for now. Scientists have kept these enemies contained in test tubes to stop the spread of a highly deadly epidemic occurring. However, if a virus were to become lose, one can only wonder what would happen.

Even fungi and bacteria and inhabited by viruses and are occasionally destroyed by them. A virus makes copies of itself in a cell until eventually the cell gets pigged with virus and pops and the viruses spill out of the broken cell. If enough cells are destroyed, such as they do in the case of Ebola, the host dies. A virus does not "want" to kill its host. That is not in the best interest of the virus, because then the virus may also die, unless it can jump fast enough out of the dying host into a new host.

“Not all chemical weapons kill, many of them cause sickness and pain to immobilize the victims.” According to ThinkQuest, in some cases there is bacteria in chemical weapons to create a reaction. These bacteria could spread and would cause more harm than good. Some of these new viruses will not have cures and could cause genetic mutations, which then would be passed on to offspring spreading it even farther. It is not just war that will be affected by chemical weapons, but terrorism to. If these chemical weapons get out terrorist strikes will not just become more frequent, but more deadly too.

The human immune system cannot eradicate it, since the target of this virus is the immune system itself. Researchers are being conducted to figure out the reason for it. An infected person may experience a brief period of influenza-like disability, during the starting phase, followed by a prolonged period without any syndrome. As the disability progresses, it deteriorates the immune system more and more, making it more prone to get diseases, such as tumors and opportunistic infections which may prove to be fatal to the infected person. AIDS stands for Acquired Immunodeficiency Syndrome Let us break it down, to understand it in a better way: A - Acquired - AIDS is not inherited from the ancestors.

These infections include opportunistic infections and tumors that would otherwise be harmless to humans. Individuals infected with the virus , if untreated, have low levels of CD4+ cells leading to progressive failure of the immune system, resulting in the development of AIDS( acquired immunodeficiency syndrome). AIDS is the final stage of the disease , but it is not the cause of death . Instead, the arising opportunistic infections are life threatening to individuals with depleted immune systems.CD4+ T cell depletion is progressive throughout HIV-1 infection. Direct and indirect cel... ... middle of paper ... ...he majority of these cells are found in the bone marrow,thymus ,lymphoid tissues ; lymph nodes,spleen,mucosa,and tonsils.

Citizenry around the world are familiar with HIV, human immunodeficiency virus, which is a virus that can lead to acquired immunodeficiency syndrome, AIDS. Unlike other viruses, the human body is unable to get rid of the HIV virus. Once you’re infected, you carry the HIV virus for the remainder of your life. The HIV virus is spread through body fluids, and affects specific cells of the immune system called CD4 cells, or T cells. Over time, this virus can destroy such an abundance of these cells that the body is eventually unable to fight off infections and diseases.

Once a virus finds the cell, it injects a new genetic code that causes the cell to turn into a virus factory. It will eventually destroys the cell, but the process makes large amounts of viruses that can then go out and find a new cell to infect, and start the cycle over again. However with an engineered virus, such as the Oncolytic virus, it only targets the infected cells and leaves the healthy cells untouched. Virotherapy takes viruses and reprograms them into targeting only the malicious and infected cells. More specifically it reprograms the somatic cells to generate Induced Pluripotent Stem Cells (iPSCs), adult cells that have been genetically reprogrammed to an embryonic stem cell–like state by being forced to express genes and factors important for maintaining the defining properties of embryonic stem cells.

Human Immunodeficiency Virus, is also known as HIV. Human Immunodeficiency Virus attacks and weakens the immune system by causing important cells that fight disease and infection to vanish. HIV is most like other viruses, the flu or the common cold, except there is a difference. As time passes, the immune system can clear out most infections out of the body. The situation with HIV is the human immune system can't seem to dispose the infection.

Here’s the most terrifying part: The scabs are filled with virus and may fall off and attach to your clothes, bed sheet, towels or anything and anyone you have contact with infecting them with the great smallpox, too. As mentioned before, smallpox may lead to the failure of organs. This result is caused by the damaging of cells. And why does the cells damage? Smallpox can be easily and more efficiently spread through the inhalation and exhalation of a person, which means that the virus, according to Vijaya Khisty Bodach, will first get inside the cells lining the throat and hijack the cellular machinery to make millions more smallpox ... ... middle of paper ... ...a vaccinated person growing cow heads was made.

Once HIV enters the body, it will infect the CD4 cells and begin to use those cells as its own “HIV factory.” HIV will therefore begin to destroy your immune system leaving you susceptible to opportunistic diseases. HIV targets your immune system... What does HIV infect and how? HIV affects your immune system. Your immune system can be thought of as your body’s defense line! In which, you have millions of 'soldiers' (T-helper cells) helping you ward off almost any foreign invaders.
