With a disease that doesn’t discriminate towards any group, HIV/AIDS is a disease that is impacting the world at an alarming rate. It doesn’t matter your age, sex, race, sexual orientation, this disease impacts every demographic. According to the Centers for Disease Control and Prevention (2013), “Worldwide, there were about 2.5 million new cases of HIV in 2011. About 34.2 million people are living with HIV around the world.” There are many myths and confusion about this disease, and in this paper I’m going to discuss what HIV and AIDS are, as well as its impact it’s making around the world. Although there is no cure for this disease there are ways that your chances of contracting it are decreased, as well as medical treatments that you can receive to slow the progression.
The human immunodeficiency virus; better known as HIV, was discovered by researchers looking for the cause of AIDS. In 1984 the first discovery of the virus was made. There is some controversy on who had discovered first, but the fact remained that the cause of AIDS was identified. In 1987, researchers formed together and named it the human immunodeficiency virus. This virus takes over the CD4 cells in the immune system and duplicates itself. Although the damage that HIV will produce is extensive, it starts off slowly and then ultimately destroys the immune system. The virus will slowly tear down the body, making it very weak. When the immune system is weak it is more susceptible to opportunistic infections. When the CD4 cells, or immune cells have reached levels below 200, HIV has now progressed towards AIDS other known as auto immune deficiency syndrome
When there are certain symptoms of HIV present all at once it is then diagnosed as auto immune deficiency s...

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...
Acquired Immune Deficiency Syndrome (AIDS), specific group of diseases or conditions that result from suppression of the immune system, related to infection with the human immunodeficiency virus (HIV). A person infected with HIV gradually loses immune function along with certain immune cells called CD4 T-lymphocytes or CD4 T-cells, causing the infected person to become vulnerable to pneumonia, fungus infections, and other common ailments. With the loss of immune function, a clinical syndrome (a group of various illnesses that together characterize a disease) develops over time and eventually results in death due to opportunistic infections (infections by organisms that do not normally cause disease except in people whose immune systems have been greatly weakened) or cancers.
HIV, also known as Human Immunodeficiency Virus, is a virus that attacks the body’s immune system. If left untreated, HIV reduces the number of CD4 cells in the body, which makes a person more likely to get infections or infection-related cancers. HIV can also lead to AIDS (acquired immunodeficiency syndrome), if it is not being treated (aids.gov). There is no effective cure for HIV, however with proper treatment and medical care, HIV can be controlled. In
HIV goes through several different movements before it leads to AIDs. The first step is the serioconversion illness. This symptoms of this illness is very similar to the flu and an affected individual will typically experience this 1-2 months after connection with HIV. The next phase is asymptomatic infection in which the patient does not have any symptoms. During this step the immune system is starting to go downhill. A great deal depends on how long this phase will last such as, how fast the HIV virus replicates and how the patient’s body deals with the virus. Some patients can stay in this phase for almost 10 years without any signs or symptoms. Persistent generalized lymphadenopathy is when the lymph nodes become infected and enlarged. The HIV affected patient can endure swollen glands during any stage of the disease. The next phase of the disease is symptomatic infection. During this time symptoms will reveal themselves and often opportunistic infections, but AIDS has not developed yet (Masur H, 2007). The final phase is AIDS. The patient’s CD4 T-cell count is below 200 cells/mm3 and the patient is starting to have severe immunodeficiency. Patient begins to have severe opportunistic infections an...
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) leads to the life threatening Acquired Immunodeficiency Syndrome (AIDS). HIV only lives in the blood and other bodily fluids. Concentrations of HIV are small in vomit, sweat, tears, and saliva and cannot be transmitted by those fluids. The main transmission is through fluids like semen, vaginal fluids, and rectal mucous during sexual contact, breast milk and amniotic fluid passing to children, and blood during transfusions and exposure. Beginning stages of HIV start with the acute infection. During the first 2 weeks to a month after exposure to the HIV infection, most infected individuals with display symptoms of a severe flu. The symptoms include fever, swollen glands, sore throat, rash, muscle and joint aches and pains, fatigue, and headache. The early period of infection is known as the “acute retroviral syndrome” (Stages, 2013). Once the virus is out of the acute stage it enters into the latency stage where it continues to replicate but no symptoms are shown. As the infection progresses and the immune system beco...
Human immunodeficiency virus (HIV) is an enveloped retrovirus. It affects the immune system and the body loses its ability to fight diseases. It is mainly transferred by sexual contact. However, it can also be transmitted by contact with body fluid like blood, breast milk and so on (CDC, 2016). A patient is said to have AIDS when he/her suffer from many opportunistic infections (CDC, 2016).
AIDS was first discovered in the United States in 1981. Since then, this epidemic has affected approximately 40 million people worldwide. AIDS is a life threatening illness that is caused by the HIV infection. When the HIV virus enters the body it begins to destroy the immune system impairing its ability to fight off certain infections and diseases. About a month after being infected, a person develops a viral infection. The viral infection is similar to the flu and causes fever, fatigue, weight loss, and swollen glands. These symptoms usually subside, and a person may not develop AIDS for up to 10 years after being infected with HIV. During this time, the HIV virus continues to multiple and destroys cells of the immune system. A person is diagnosed with AIDS when the immune system is so deteriorated by HIV that it can no longer fight off certain infections and diseases known as "opportunistic infections." These infections cause a person to suffer from a variety of illnesses including weight loss, persistent diarrhea, coughing, nausea, swollen glands, and shortness of breath. The infections can last from several days to several months and are often difficult to treat. AIDS patients are also prone to develop certain cancers. These cancers include Kaposi's sarcoma, cervical cancer, and lymphomas. Although each of these cancers are treatable, AIDS patients suffer severe cases of these cancers because of their weakened immune system. It is often difficult to determine if a person will make it through a particular illness or not. In most cases, people do not die from AIDS but from complications from illnesses that define AIDS. When a person is diagnosed with having AIDS, their estimated survival time is 2-3 years.
According to the World Health Organization, HIV/AIDS is the leading infectious killer in the world with the death toll estimated around 36 million people (WHO, 2014). HIV stands for human immunodeficiency virus. HIV is very different from other communicable disease because the virus takes over cells in the body and weakens the immune system. It does that by destroying healthy, important cells that fight off disease and infection. The reason your immune system cannot fight this virus is still a question many scientists are seeking to answer, (AIDS, 2014). Scientists know that HIV is capable of being undetected in the cells of our bodies for long periods of time. The HIV virus invades our T cells, which are in charge of cellular immunity, and is able to duplicate itself in these cells and then destroy them. When too many T cells become destroyed the body is unable to fight off this virus, which leads to Acquired Immunodeficiency Syndrome or AIDS, (AIDS, 2014).
HIV is transmitted from person to person during specific activities when an infected person’s bodily fluids, for example, semen, vaginal fluids, anal secretions or blood enters another person’s body (UNICEF, 2008). For transmission to occur these fluids have to come into contact with damaged, broken skin or the mucous membranes found inside the rectum, vagina, mouth or penis; through certain sexual behaviors or by using an infected needle/drug equipment (NHS, 2014). Once infected this virus gradually attacks and destroys certain cells of the body’s immune system. The very system that protects and defend the body from illness or infections (The Well Project, 2015). HIV specifically targets the CD4 cells or T ‘helper’ cells and reduces them in number causing the immune system to weaken, making the body vulnerable and less able to fight off infections (AVERTing HIV, 2015). If left untreated, HIV destroys so many of these cells that the immune system becomes too badly damaged, making the body vulnerable to opportunistic infections and HIV related cancers. These infections would cause no reaction in a person with a normal immune system but for an HIV infected person, they can cause devastating illnesses (Aids.gov, 2010). This is the final stage of the HIV virus and is known as Acquired immunodeficiency Syndrome (AIDS). Unlike other viruses, the body cannot get rid of HIV, once caught the person has
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.
The emergence of HIV/AIDS is viewed globally as one of the most serious health and developmental challenges our society faces today. Being a lentivirus, HIV slowly replicates over time, attacking and wearing down the human immune system subsequently leading to AIDS (Acquired Immunodeficiency Syndrome) at which point the affected individual is exposed to life threatening illnesses and eventual death. Despite the fact that a few instances of this disease have been accounted for in all parts of the world, a high rate of the aforementioned living with HIV are situated in either low or medium wage procuring nations. The Sub-Saharan region Africa is recognized as the geographic region most afflicted by the pandemic. In previous years, people living with HIV or at risk of getting infected did not have enough access to prevention, care and treatment neither were they properly sensitized about the disease. These days, awareness and accessibility to all the mentioned (preventive methods, care etc.) has risen dramatically due to several global responses to the epidemic. An estimated half of newly infected people are among those under age 25(The Global HIV/AIDS Epidemic). It hits hard as it has no visible symptoms and can go a long time without being diagnosed until one is tested or before it is too late to manage.
