The human immunodeficiency virus, known more commonly as HIV or by the syndrome it ultimately leads to the acquired immunodeficiency syndrome or AIDs, is caused by a RNA retrovirus.1 Morphologically, the virus appears spherical in shape and is enveloped made from two layers – both being primarily built using lipids taken from host cell membranes.2 Specifically, human cell membranes are taken up by the virus as it buds from the host cell2 after the host cell approaches death from the inability to meet its own physiological needs. Likewise, because the hosts’ membrane coats or more accurately ‘envelopes’ the virus, the hosts’ proteins are embedded within the membrane and on the membrane’s surface as well.2 However, the last essential …show more content…
HIV has a human reservoir (only humans can get infected for HIV anyway) and its means of transmission is vehicle in nature using fluids from our bodies.1 For example, a patient infected with HIV would have the virus found in blood, semen, vaginal secretion, breast milk, saliva, pus and other fluids excreted from wounds
Hamilton story is an epic one. He helped the nation in more ways that people can count, he fought every other founding father for his own ideals, and he was killed by his once best friend, being the only founding father to be killed. Although people say that Hamilton’s efforts to change america ended up hindering it more because he attempted to thwart a political race, he has a long history of failure, and because he publicly thrashed founding fathers in his newspaper articles, Hamilton was an amazing man. Hamilton was vowed to fix America financially, he assisted George Washington, and had plans to make america better.
The life of Edgar Allan Poe is not a pleasing story to be told. Ever since he was a little boy, he had a tragic life that would only get worse. When he was around three years old, his father left and his mother passed away from tuberculosis. Poe was later taken in by a couple. From there on he went to school, was in the army, got married, and worked very hard to get his stories published. He and his wife traveled a lot in order to sell his stories to papers. Because nobody would see his stories the way he does, he drowned his sorrows in alcohol. He and his family starved greatly because of his unemployment, which caused his family to become ill. His wife passed, which only made things worse. He then began to lose his temper, which resulted
At the height of the Athenian Empire, 5th century BCE, one of the greatest temples of all time was erected, the Parthenon a temple dedicated to the cities patron goddess Athena Parthenos. Built on the hills of The Acropolis between 447-432 BC, The Parthenon was made to an all-encompassing formula creating perfect proportions and dimensions. This perfect temple celebrates the magnificent power of Athenians years earlier that had successfully defeated the Persians during the
HIV (Human Immunodeficiency Virus) is a virus that cause initial HIV infection and, as the virus proliferates in the body, AIDS (Acquired Immune Deficiency Syndrome). HIV affects the immune system by exploiting, and, eventually, destroying a specific kind of immune cells. That allows for the gradual deterioration of a person’s immune system, which ultimately causes death from minor opportunistic infections, which are normally perfectly curable and generally do not cause major consequences for health. HIV has a limited range of transmission ways. It is only transmitted through the direct contact of body fluids, which include blood, semen, vaginal fluids, and breast milk [1]. This means that most of the modes of transmission include activities that are moralized by society, such as intravenous drug use and sexual contact [1]. However, it can also be transmitted through “innocent pathways”, such as during breastfeeding (mother to child) and blood transfusion. HIV is a very young, still poorly understood virus. It was first clinically observed in the summer of 1981 in San Francisco, where it was spotted as a type of sarcoma, mostly spotted in the gay population. In the beginning of the global epidemic, there was a huge misunderstanding of the disease [2]. Back then, a general sentiment about HIV was that of a “rather devastating outbreak” [2] , associated with homosexuality and drug use (to the point
HIV is transmitted via semen, blood, breast milk, and vaginal and rectal secretions. An infected mother can pass HIV to her unborn child via placenta or during birth if the proper measures are not undertaken. Sharing needles can also infect an individual due to possible contamination of infected blood (Holland, 2013).
Human Immunodeficiency Virus, more commonly known as HIV, started as a serious illness and eventually led to death rapidly. About thirty years ago HIV was discovered as a transition from chimpanzees to humans in West Africa. The researchers believed that the chimpanzee version of the immunodeficiency virus most likely was transmitted to humans and mutated when humans hunted these chimpanzees for food, coming into contact with their infected blood. Over the years, the virus slowly spread across Africa and later into other parts of the world, such as the United States (“Where did HIV come from” all). In the U.S, 4,000 people are diagnosed with HIV every year (“HIV/AIDS at A Glance”). Instead having any symptoms or signs of this epidemic illness, the rate of victims grew greatly (“What is HIV”). As a result, HIV is not completely curable, but there are ways to control it. Testing positive for HIV now provides updates of additional information not known about including causes, signs, treatment, and prevention. The lack of knowledge on sexually transmitted diseases aren’t fulfilled as they should be.
The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
HIV, or the human immunodeficiency virus, is a virus found in human beings that primarily infects cells that are part of the immune system, but can affect other cell types as well. HIV is what is called a retrovirus, meaning it has the coding system of RNA opposed to DNA. AIDS is a virus that is caused by HIV and has many different symptoms that vary with different individuals. HIV causes symptoms such as severe infections that can lead to pneumonia and changes of the skin like red or purple patches. The virus can spread through sexual contact or the exchange of blood.
Human Immunodeficiency Virus or HIV is a single stranded positive sense RNA retrovirus that infects CD4+ T-Cells, Macrophages, and Dendritic Cells. (Viral Zone) Information concerning HIV’s routes of transmission, and epidemiology, as well as the course of the disease can be found below.
Human Immunodeficiency Virus or HIV is a virus that no one wants to talk about. Due to lacking media attention, judgment, and ignorance, many people are not knowledgeable about the virus. In the 1980s people became aware of the HIV virus because of the epidemic that arose, but many people didn’t react appropriately to it. One of the reasons there was not a huge reaction was because nobody was aware of the disease. However, scientist soon discovered that everyone was susceptible to the virus. One of the original thoughts of HIV, was that it came from Africa, originating from West African monkeys. Along string of this virus was found and
Human immunodeficiency virus (HIV) is a virus that alters the immune system, making the population with HIV vulnerable to infections and diseases. HIV can be found in the body fluids of an infected person. The virus is passed from one person to another through blood-to-blood and sexual contact. HIV can be transmitted in many ways, such as vaginal, oral sex, anal sex, blood transfusion, and contaminated needles. Patients with HIV cannot clear to virus out of their bodies like most other viruses do. Once a patient is diagnosed with HIV, he will have it for life. According to the Center for Disease Control and Prevention (2015), HIV can stay in the body for a long time and attack ones T-cells or CD4 cells, which are the cells that are needed
HIV first binds to CD4+ helper T-cell with the gp120 protein on the HIV virus and the chemokine receptor, CCR5, on the CD4+ helper T-cell. (6) The viral core then enters the cell and the virion’s protein membrane fuses with the cell membrane. The virus then injects its RNA into the cytoplasm where reverse transcription occurs so synthesize HIV DNA, also called provirus. The provirus is then transferred into the nucleus were it is integrated into the host genome. The infected cell then transcribes and translates the provirus. The viral proteins and some of the viral RNA gather at the edge of the cell membrane and bud off from the infected cell. The newly formed HIV virus goes on to infect other CD4+ helper T-cells, while the infected cell dies. (6) The virus can evolve to use the
In most cases, when the issue of a disease comes up, most people are worried about; the severity of the disease, how it can be managed in conjunction with how it can be transmitted, so basically if it is highly contagious and most importantly, if any cure has been established for it. Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome(HIV/AIDS) is one of the most difficult epidemics to control. This is because, the HIV virus attacks the very cells designed to control and as such, can avoid exposure to treatments which is the major reason why a cure for it hasn’t been found. Owing to the lack of their knowledge of the severity of the virus, a shadow of illiteracy is cast on them because they have no access to the knowledge on how to protect themselves from the virus, let alone, prevent the spread of it. This virus is detrimental not only when a person is infected but also, when a people aren’t properly educated about the severity, prevention and steps to take after one has been diagnosed, so as to make efforts to increase the quality of life for both themselves and the people around them.
Human Immunodeficiency Virus (HIV) is a virus that infects the cells of human immune system, causing destruction and impairing the cellular functions. Progressive deterioration of the immune system at cellular level causes associated infection to undermine the immune system putting the patient at risk of opportunistic infections. Acquired Immunodeficiency Syndrome (AIDS) is the most advanced stage of HIV. AIDS is caused when HIV related cancers hit the immune system by 20 or more opportunistic infections. According to the World Health Organization (WHO) by the end of 2016, 36.7 million people (30.8-42.9 million) were living with HIV globally. Approximately 0.8% (0.7%-0.9%) adults between the age group of 18-45 were living with HIV and 76%
HIV-1 unique trespassing method and integration in the host cells makes the virus a rigorous parasite for the immune system to detect and defend its self from the virus. By understanding the life cycle of the virus, we can understand its success rate of reproduction under millions of regulatory immune cells. After been introduced into the host body, by sexual transmission or breaking of the skin, we can begin to follow the beginning stages of HIV, which would lead to AIDS without proper
