The human acquired immune deficiency syndrome (AIDS) is a retrovirus that is found in two forms HIV-1 and HIV-2. The AIDS virus is a relatively new virus receiving attention in the 1980’s. As quickly as it swept through the world, was as quickly it went to epidemic proportions. Acquired immune deficiency syndrome is a virus that enters and infects the body through sexual activity with an infected party. AIDS is a very infectious and dangerous virus that causes the death of many humans. AIDS is characterized by two single stranded RNA and uses enzyme reverse transcription to integrate into the hosts DNA.
The AIDS virus is transmitted through sexual activity with someone that is infected with the virus. HIV has the most genetic diversity seen in viruses. HIV enters the immune system through bodily fluids from an infected party. Upon entering the body the virus (two single strand RNA strands) it replicates using reverse transcription to get into the DNA. HIV favors entering cells with the CD4+ receptor, which allows for binding. While just not obtaining the receptor does not make a person 100% less susceptible to the virus, it still allows the person to get the virus. The lack of receptor comes from ancestors that survived the Black Death in Europe. Their adaptation was passed on to their children and created a higher resistance to AIDS as well. After attachment to cell preferably with CD4+ HIV must now go into viral transcription.
HIV-1 and HIV-2 are two distinct forms of the virus, which stem from different origins in the evolutionary tree. The split between the two forms occurred over 150 years ago. Both forms of the HIV virus come from the simian immunodeficiency virus (SIV) virus found in other primates. The two forms come ...

...uld begin infecting humans. While the origins of the HIV-1 form of HIV is controversial and speculated through scientific research the origin of HIV-2 is more concrete.
The evolutionary history of HIV-2 originates from the strain of 〖SIV〗_sm found in Sooty Mangabey monkeys. HIV-2 is most likely to have originated in West Africa and remain most prevalent in that area as well. HIV-2 can be separated into six discrete phylogenic lineages. Each of the six discrete lineages is equally related to each other than it is to 〖SIV〗_sm.
The AIDS virus has the gift of replicative powers. The virus replicates at a very fast pace, and also has a very high mutation rate. Coupled together beating the virus is very hard, due to the fact that it is always evolving to fight the medications thrown at the virus. Every strain of AIDS within each infected human is distinct to them.
It is a virus that gradually attacks the immune system, which is our body 's natural defence against illness. If a person becomes infected with HIV, they will find it harder to fight off infections and diseases. AIDS stands for acquired immune deficiency syndrome. AIDS is a syndrome caused by the HIV virus. It is when a person’s immune system is too weak to fight off infections, and develops when the HIV infection is very advanced.
If one compares the epidemiology and social impact of these diseases they prove to be quite similar. The current AIDS epidemic has the potential to be the most dangerous and destructive plague of the millennium. No one knows exactly how the AIDS virus erupted. However, one presently dominant theory states that AIDS originated from monkeys in Africa
Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system transmitted between people by the mixing of bodily fluids. It is an extremely deadly disease that has killed over thirty-six mi...
Different people define success in many different ways. What is considered success by one person may be viewed as failure by another person. Randy Shilts, a homosexual newspaper reporter / author, attempts to make fundamental changes in America’s opinion on AIDS. In Randy Shilts’s essay, "Talking AIDS to Death," he speaks of his experiences as an "AIDS celebrity." At the core of Shilts’s essay is the statement, "Never before have I succeeded so well; never before have I failed so miserably"(221). Shilts can see his accomplishments from two points of view- as a success and as a failure. Despite instant fame, Shilts is not satisfied with the effects his writings has on the general public. Shilts’s "success" and reasons for failure can both be considered when one decides whether or not his efforts were performed in vain.
In the early 1980s deaths by opportunistic infections, previously observed mainly in organ transplant recipients receiving therapy to suppress their immune responses, were recognized in otherwise healthy homosexual men. In 1983 French cancer specialist Luc Montagnier and scientists at the Pasteur Institute in Paris isolated what appeared to be a new human retrovirus—a special type of virus that reproduces differently from other viruses—from the lymph node of a man at risk for AIDS (see Lymphatic System). Nearly simultaneously, scientists working in the laboratory of American research scientist Robert Gallo at the National Cancer Institute in Bethesda, Maryland, and a group headed by American virologist Jay Levy at the University of California at San Francisco isolated a retrovirus from people with AIDS and from individuals having contact with people with AIDS. All three groups of scientists isolated what is now known as human immunodeficiency virus (HIV), the virus that causes AIDS.
According to the Public Health Agency of Canada HIV – the Human Immunodeficiency Virus - is a virus that attacks the immune system, resulting in a chronic, progressive illness that leaves people vulnerable to opportunistic infections and cancers. (Canada 2008) Essentially over time, when your body can no longer battle the virus it progresses into a disease know as Acquired Immunodeficiency Syndrome or AIDS. The transmition of HIV occurs when a person’s contaminated body fluids enter another individual. Unprotected sexual intercourse (vaginal, anal or oral), sharing needles, using unsterilized equipment for body modification, mother to infant transmition, as well as occupational exposure in health care are all ways HIV can be spread. HIV/AIDS as an illness is relatively new. The first reported case of AIDS in the world was in 1981, and a year later in Canada. Scientists all around the world are busy searching for a cure or vaccine to treat the millions of people internationally dying of HIV/AIDS.
Acquired Immune Deficiency Syndrome (AIDS) was first recognized as a new disease in 1981 when increasing numbers of young homosexual men succumbed to unusual opportunistic infections and rare malignancies (Gallant49).During this time, many people were contacting this disease because it was not discovered yet and people did not have knowledge about it.Scientists believe HIV came from a particular kind of chimpanzee in Western Africa. Humans contracted this disease when they hunted and ate infected animals. A first clue came in 1986 when a morphologically similar but antigenically distinct virus was found to cause AIDS in patients in western Africa (Goosby24). During this time, scientists had more evidence to support their claim about this disease. Once discovered this disease was identified as a cause of what has since become one of the most devastating infectious diseases to have emerged in recent history (Goosby101). This disease was deadly because it was similar to the Black Death, it was killing majority of the population. Since its first identification almost three decades ago, the pandemic form of HIV-1 has infected at least 60 million people and caused more than 25 million deaths ...
Human immunodeficiency virus (HIV) is a retro virus that causes AIDS. HIV is a virus that can only be contracted between human to human. HIV weakens your immune system because this virus is destroying cells that fight diseases and infection in your body. A virus can only produce itself by taking over a cell in the body of its h...
Human Immunodeficiency Virus (HIV) was once considered a taboo disease that made its appearance in the United States around the late 1970s. Little was known about the virus and it was originally thought to just be found in the gay male community. As more and more research has been done people now understand the virus and realize that it affects men and women as well as all races, ages, and sexual orientation. It is believed that HIV is a mutated form of the Simian Immunodeficiency Virus (SIV) that is found in chimpanzees. It most likely moved to the human population from people hunting monkeys, coming in contact with their blood, and eating their meat (The Origin of HIV/AIDS, 2014).
Even though AIDS is heavily researched, its origin still remains a partial mystery. It is know that HIV is a zoonosis, a human disease acquired from animals. The virus evolved from a Simian Immunodeficiency Virus (SIV): a type of slow virus found naturally in monkeys and apes which, while not harming the host, produces diseases in other primates (Caldwell 97).
HIV is the human immunodeficiency virus; this virus can lead to acquired immune deficiency syndrome, or AIDS. Accoring to Avert, 2.6 million people became infected with HIV in 2009, there are now an estimated 33.3 million people around the world who are living with HIV. HIV is transmitted by the exchange of bodily fluids via sharing contaminated syringes, from infected mother to the child, and sexual contact. Contact with blood, semen, vaginal secretions, breast milk, or saliva that is contaminated with HIV, puts an individual at higher risk for contracting HIV. However, HIV cannot be transmitted by touch, coughing, or by bits from insect vectors.
A person can come into contact with HIV/AIDS in several ways. The main premise is that HIV is found in human b...
HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999, researchers had discovered that HIV is derived from chimpanzees native to west equatorial Africa. This epidemic is spreading throughout countries and infecting 14 thousand victims every day. Learning about HIV includes knowing how to contract the virus, understanding most of the people it affects, how to prevent the spread of it, and knowing what treatments are available.
In 1981, a new fatal, infectious disease was diagnosed--AIDS (Acquired Immuno-Deficiency Syndrome). It began in major cities, such as New York, Los Angeles, Miami, and San Francisco. People, mostly homosexual men and intravenous drug users, were dying from very rare lung infections or from a cancer known as Kaposi’s sarcoma. They have not seen people getting these diseases in numerous years. Soon, it also affected hemophiliacs, blood recipients, prostitutes and their customers, and babies born from AIDS-infected women. AIDS was soon recognized as a worldwide health emergency, and as a fatal disease with no known cure, that quickly became an epidemic. When high-profile victims began to contract the virus, such as basketball star Magic Johnson, the feeling spread quickly that anyone, not just particular groups of people, could be at risk. AIDS impairs the human body’s immune system and leaves the victim susceptible to various infections. With new research, scientists think that the disease was first contracted through a certain type of green monkey in Africa, then somehow mutated into a virus that a human could get. AIDS is a complicated illness that may involve several phases. It is caused by a virus that can be passed from person to person. This virus is called HIV, or Human Immuno-deficiency Virus. In order for HIV to become full-blown AIDS, your T-cell count (number of a special type of white-blood cells that fight off diseases) has to drop below 200, or you have to get one of the symptoms of an AIDS-induced infection.
Acquired immune deficiency syndrome (AIDS) is a fatal physical condition that is caused by the human immunodeficiency virus (HIV). The virus damages the human body’s immune system, so that the body cannot protect itself from bacteria, viruses, and prions that cause diseases. With severely lowered defenses, AIDS patients die from common illnesses such as pneumonia, diarrhea, cold, and tuberculosis. The HIV virus does not directly attack its victim; the disease that patients suffer from after receiving the virus is what hurts and kills them. AIDS is a disease that is transmitted easily through unprotected sexual intercourse, sharing of needles, blood transfusion, and childbirth.
