HIV, Human Immunodeficiency Virus, is one of the most deadliest virus in human history, however it was not until the 1980s when the severity of HIV began to rise, causing many people around the world to lose their lives.
HIV is a virus that attacks the immune system of a person and weakens it so the body can no longer fight against illnesses. This virus kills the T-helper cell ( a type of white blood cell that fights off bacteria ), and creates copies of itself inside the T-helper cell. HIV is found in bodily fluids such as semen, blood, anal fluids, and breast milk. It cannot be transferred through bodily fluids such as sweat, saliva, or urine. The most common way of transmitting HIV is through unprotected sex, infected needles, drug taking equipment, or pregnancy and birth.
AIDS on the other hand is a syndrome caused by the HIV virus. This is when the body can no longer defend itself. There are no cure for HIV nor aids but with treatments a person can live a long healthy life if they receive treatment early.

Scientific research discovered a strand of the SIV found in chimpanzee was found almost identical to the HIV in humans in 1999. Clearly there is a relationship between SIV and HIV, and many scientists came to a conclusion that HIV originated from SIV after mutation in the human body. But the question is how did the SIV virus from apes get into the body of humans? Research concluded that HIV originated from Kinshasa in the Democratic Republic of Congo around the 1920s when HIV crossed species from chimpanzees to humans. HIV is a virus that is transmitted through bodily fluids so the idea of hunter and prey came into play. The SIV virus which existed in apes was transferred to humans when the hunters in the area killed and ate the chimpanzee.Therefore, this proves that chimpanzee was the source of
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.
...cused of being patient zero and the one who purposely and knowingly infected as many as 250 men a year on both sides of the Atlantic was nothing but one of the many wrong hypotheses made in this process of finding the origin of the HIV/AIDS virus. The fact that he had single handedly started the epidemic, today is largely discredited by most scientists. With time computer models estimated that the first human infection occurred around 1930, give or take 20 years. The earliest known infection of an identified human dates back to 1959 which was found in a plasma sample taken from an adult male living in the Belgian Congo. Many assumptions and hypotheses were made and a human eating a chimp seems to be the likeliest form the infection occurred.

that transmitted the HIV virus to humans through bites (Forsyth). As people migrated it reached Haiti and then spread to America (Clark p. 65).
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...
By searching for the causative agent of infectious disease the focus can then be shifted into discovering preventative and treatment of the disease. Examples of this process are the outbreak of acquired immunodeficiency syndrome (AIDS) and bovine spongiform encephalopathy (BSE). As published by McEwen & Wills (2011), BSE was identified as a protein transmitted through the ingestion of contaminated meat. Prevention and interventions were created as a result of the discovery of the protein. Comparably, AIDS, was first identified by the Centers for Disease Control and Prevention in September of 1982, however, months passed before the causative agent was deemed a retrovirus later to be determined the human immunodeficiency virus (HIV). Even before the virus was isolated methods of transmission was recognized and interventions were acknowledged (McEwen & Wills, 2011).
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...
HIV is the human immunodeficiency virus; this virus can lead to acquired immune deficiency syndrome, or AIDS. According 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 the 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.
Therefore, these viruses differ immensely from other viruses because of their intent. Most viruses attack different cells and are thus left open to be destroy by T- cells and white blood cells. However, they fight back leaving them as one of the most complicated viruses and most devastating virus that has limited science research over the past 30 years. It has been noted that AIDS was seen as mostly transferred through homosexuals ...
It is a virus AIDS is a fatal disease which renders the body helpless against other diseases. Patients lose the ability to defend themselves against viri. and die from infections.
Human immunodeficiency virus (HIV) is a slow moving retrovirus that eventually causes acquired immunodeficiency syndrome commonly called AIDS. This combo disease known as HIV/AIDS is labeled as a pandemic and has caused controversy throughout the whole world. The disease begins when a person infected passes on the HIV virus through sexual secretions, blood transfusions, and using dirty needles. The virus enters through vaginal or anal openings and through open cuts, once the virus enters a person’s blood stream they are infected with HIV however they may not necessarily have AIDS (WEBMD). Symptoms of HIV include lethargy or sleepiness, weight loss, and flu like symptoms after a while AIDS eventually develops and is the finally or most advanced stage of the disease the symptoms are the same as HIV and also includes vision loss, weight loss, memory loss, and eventually organ failure (AIDS.gov) The first reports of AIDS came from young gay men in New York and San Francisco.
Most people recently infected by the AIDS virus look and feel healthy. They may not show symptoms for several years, but the condition is eventually fatal. Even though one might not know that they have this deathly disease, and remain apparently healthy, they can still pass it along to others, and they then pass it on to others, etc, until an abundant amount of people are infected. Symptoms may include fever, fatigue, weight loss, skin rashes, a fungal infection of the mouth known as thrush, lack of resistance to infection, and swollen lymph nodes. HIV, the virus that causes AIDS, is transmitted through blood, semen, and vaginal fluid. The virus is usually transferred through sexual intercourse, the transfusion of virus-contaminated blood, or the sharing of HIV-contaminated intravenous needles. HIV cannot penetrate intact bodily surfaces, such as skin, and quickly perishes outside the human body. Consequently, AIDS is not spread by casual physical contact.
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.
