The Human Immunodeficiency Virus ( Hiv ) Essay

Since its identification approximately two decades ago, HIV has increasingly spread globally, surpassing expectations (1). The number of people living with HIV worldwide is estimated to be 36 million, with 20 million people having died from the disease, giving a total number of 56 million being infected (1). In 2000 alone, 5.3 million people were infected with HIV and there is potential for further spread. HIV infection rates vary all over the world with the highest rates in Sub-Saharan Africa (1). Responding to this epidemic has been a challenge as infection rates have increased worldwide despite tremendous public health efforts by nations (1). The identification of potential interventions to reduce the magnitude of the problem has

We have been aware of HIV and AIDS since the 1970s (Miller, 2012), and though there have been treatments and reduction in the number of people infected, the disease remains. The disease results in death usually following opportunistic infections as a result of AIDS destruction of the immune system, but thanks to modern medicine “many people

In the 1980s, a mysterious disease began to take the lives of Americans. With the cause unknown, a fear grew among Americans. An unusually high rate of people was becoming sick with strange and rare diseases. When experimental treatments failed to work, people died. This mysterious disease is what we now know as HIV–Human Immunodeficiency Virus. In the past thirty-five years, the HIV has taken many turns in history. Although we do not hear about HIV and AIDS now, it is still a prevalent issue in the United States and in the world.

There is some good news in the fight against HIV. Between 2005 and 2014 new diagnosis of HIV have fallen by 19% nationwide (CDC, 2017). Those living with HIV are now living longer, healthier lives and have the opportunity to

Human immunodeficiency virus (HIV)/AIDS is a pandemic problem affecting global health. At the end of 2015, 36.7 million people were living with HIV/AIDS globally. The rate of incidence is more prevalent in Sub-Saharan Africa with almost 1 in every 24 adults living with HIV/AIDS. In the united states, HIV/AIDS is a diversified health problem affecting all sexes, ages and races and involving the transmission of multiple risk behavior. However, with the introduction of various prevention programs and antiretroviral drugs, the incidence of HIV/AIDS has reduced.

After reading the five given articles carefully there are critical points that I would like to articulate in my reaction paper. These articles provoked me to think that we are blessed to have health professional that were able to discover HIV/AIDS and the causes of Kaposi 's Sarcoma and Pneumocystis pneumonia of homosexual men in July 1981, following the report of these cases of PCP and cases of other rare life-threatening opportunistic infections and cancers in America we began to recognize the importance of being aware of HIV/AIDS (Altman). Maybe not need

If you look at how everything has developed since AIDS was first regarded as s major threat to public health in the beginning of the 1980’s it could be said that a lot of progress has been made. Not in a way where infected individuals around the world get the treatment they need or the developing countries get completely the support necessary, but today the world is closer to that goal than years before. This is important to outline because people tend to forget the progress been made, as they are only searching for a certain ending or result. The final solution to the dilemma between distribution of drugs to all people in need and the costly and continuous research required to find a cure, is not in reach [3].

In 2014, 1.2 million people died from HIV and its related causes. In the same year, about 36.9 million people were living with HIV. Among these, 2 million were newly infected in 2014. The rate of infection has reduced by 35% between the years of 2000 and 2015. Between the same years, mortality due to HIV fell by 24%. The area with the most HIV/AIDS victims is Sub-Saharan Africa. In this region, 25.8 million people were living with HIV in 2014. The region also has 70% of the newly infected victims in the world. It is very unfortunate that more than 50% of people with HIV know that they have it. HIV testing efforts have improved with 150 million in 129 low and middle income counties getting tested. It was reported in 2015 that 15.8 million people were receiving antiretroviral therapy (World Health Organization,

Although HIV is no longer the automatic death sentence it was in the 80’s, it remains a thorn even in our modern societies. For instance, HIV treatment is exponentially expensive, and can only be afforded by residents in developed countries. In fact, most third world nations are still in the 80’s as far as HIV treatment technology is concerned. Fatality rates particularly in Africa are astronomical to say the least (Rensburg 267). With prices, for

For the epidemiology paper I chose to write about HIV. HIV is growing concern in the community and too many people are uneducated about the seriousness of this disease. HIV is terminal illness; it will eventually consume your life at some point. There are treatment options out there but being compliant with the medication regimen is crucial to the maintenance and management of this disease.

Just as clearly, experience shows that the right approaches, applied quickly enough with courage and resolve, can and do result in lower HIV infection rates and less suffering for those affected by the epidemic. An ever-growing AIDS epidemic is not inevitable; yet, unless action against the epidemic is scaled up drastically, the damage already done will seem minor compared with what lies ahead. This may sound dramatic, but it is hard to play down the effects of a disease that stands to kill more than half of the young adults in the countries where it has its firmest hold—most of them before they finish the work of caring for their children or providing for their elderly parents. Already, 18.8 million people around the world have died of AIDS, 3.8 million of them children. Nearly twice that many—34.3 million—are now living with HIV, the virus [9].

Sub-Saharan Africa is the region of the world that is most affected by HIV/AIDS. The United Nations reports that an estimated 25.4 million people are living with HIV and that approximately 3.1 million new infections occurred in 2004. To put these figures in context, more than 60 percent of the people living with the infection reside in Africa. Even these staggering figures do not quite capture the true extent and impact that this disease causes on the continent. In 1998, about 200,000 Africans died as a result of various wars taking place on the continent. In that same year, more than 2 million succumbed to HIV/AIDS (Botchwey, 2000).

HIV is the human immunodeficiency virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. AIDS (acquired immunodeficiency syndrome) is a disease in which the body's immune system breaks down and is unable to fight off certain infections, known as "opportunistic infections," and other illnesses that take advantage of a weakened immune system. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are the immune cells that normally protect us from disease.

HIV is a virus that is spread almost all over the world. Although in some places health care isn’t as developed and therefore it spreads more in those regions. Sub-Saharan Africa holds more than 70%, 25 million, of all HIV positive people in the world. Second highest is Eastern Europe together with Central Asia with 1.3 million. It is spread over most of the world, including Asia and the Pacific, the Caribbean, Central and South America, North Africa and the Middle East and Western and Central Europe (“The Regional Picture”).

The Human Immunodeficiency Virus is coming from a subgroup of retrovirus called Lentivirus which causes HIV infection leading to Acquired Immunodeficiency Syndrome (AIDS) later on among humans. AIDS is a human condition which progresses to the failure of the immune system, causing life-threatening opportunistic infections and cancers to thrive. Treatments can be given, but without those, survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. Vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells are the main target of HIV. HIV infection leads to decreased CD4+ T cells through a number of mechanisms like apoptosis of uninfected bystander cells, pyroptosis of abortively infected T cells, direct viral killing of infected cells and killing of CD4+ T cells that are infected by CD8 cytotoxic lymphocytes. When CD4+ T cells decreased into a number below critical level, cell- mediated immunity is lost making the body more susceptible to opportunistic infections.
