Immunodeficiency Virus: A Case Study

Improved Essays
HIV stands for human immunodeficiency virus. HIV is able to hide for a long period of time in the cells and attack the immune system, specially the T cells. These cells are in the body to fight infections and diseases, but when someone gets infected with HIV these invades the T cells and makes copies of itself and destroys them. As time goes by HIV can destroy many T cells, which affects the body by making the body weak and not able to fight infections and diseases anymore. HIV id divided into three stages, the early stage, the clinical latency stage, and the final stage.
The virus can be transmitted through different ways. It can be transmitted through body fluids such as blood, semen, rectal fluids, vaginal fluids, and breast milk. In order

At the end of 2013 35.5 million living with HIV and approximately 2.1 million got infected globally. HIV is most prevalent in Sub Saharan Africa with 24.5 million people living with HIV in 2013 according to the World Health Organization. This region of the world accounts for almost up to 70 percent of HIV infections globally. In 2012 there was about 1.6 million new HIV infections and nearly 1.2 million AIDS related …show more content…
The fist treatment for HIV was called AZT in 1987. Later on approximately more than 30 drugs were approved to treat people with HIV/AIDS and many more are under development. Currently there are five different HIV drugs that are classified to attack the virus at different points of the cycle. Taking three different medications controls the virus better and protects the immune system. This process is called Antiretroviral Therapy (ART). Some examples of antiretroviral medications include Nucleoside/non-nucleoside reverse transcriptase inhibitors also called “nuke” that help block the most important step of HIV reproduction process. These two medicines block the enzyme reverse transcriptase and prevent the virus from making copies of its DNA. Another include protease inhibitors that blocks the strands of DNA from getting cut into functional pieces. A third medication is called Fusion inhibitors that blocks the virus from entering the cells. Through receptor sites HIV attach and bond to the CD4 cells which prevent the virus from entering into healthy cells. Lastly integrase inhibitor disable the integrase protein that HIV uses to insert the genetic material into the CD4 cells. However the treatment have some side effects including diarrhea, nausea, heart disease, weakened bones, shortness of breath, and skin rash. Even though it has side effect these treatment has help people with HIV live longer and

    HIV (also known as the human immunodeficiency virus) is a virus which targets and attacks the immune system which in turn weakens your ability to fight infections and disease. If left untreated the HIV can lead to a disease called AIDS (which is known as the acquired immunodeficiency syndrome). HIV affects the specific cells of the immune system which are called the CD4 cells and if left untreated, HIV can eliminate so many cells from the body and ultimately the body cannot fight off other infections or disease. There are many symptoms/signs that you may have HIV. Within the first month or two upon catching HIV, almost 40% to 90% of people experience flu like symptoms which is known as ARS (acute retroviral syndrome).…

    Human Immunodeficiency Virus (HIV) is a lentivirus that attacks the body’s immune system through CD4 cells and evolves into Acquired immunodeficiency Syndrome (AIDS). HIV is transmitted by contact with bodily fluids. Symptoms of HIV are similar to simple cold symptoms including fever, chills, rash, etc. There is no cure for HIV, but it can be treated and controlled with antiretroviral therapy. There will be a more in-depth look into HIV in this paper.…

    (NIH) One of the treatments for AIDS/HIV is the use of anti-retroviral medications. This form of therapy is highly recommended for those with the virus. The use of medications as part of the treatment plan does not ensure a cure, it does however help with the progression of the disease and symptoms. Some of the medications may even help with stopping the spread of the HIV virus. The regimen of medications is tailored to the individual patient.…

    Epidemiology of the disease HIV/AIDS is now a global pandemic. As of 2012 approximately 35.2 million people are living in the world with HIV globally. Approximately 17.2 million of those people that are living with HIV are male and of that large population 16.8 million are women. The most shocking of this is the fact that 3.4 million are less than 15 years of age. The CDC is said to make estimation on the…

    The report also mentioned the relationship between incubation an anti-HIV-1 activity. If the protein was incubated for longer amounts of time, it’s anti-HIV-1 activity was reduced. Incubation degrades the protein structure at the functional level, in turn decreasing functionality and anti-viral effects. Also, proteins with a greater cationic charge exhibited higher rates of anti-viral activity signifying that charge is a critical factor in fighting HIV. This study demonstrated important findings in the fight against HIV-1.…

    HIV Infection Stages

    HIV Infection Stages HIV infection can be transmitted through few ways such as sexual contact and blood transfusion. Once a person gets infected, he will normally interact with three stages of infection which are known as acute, chronic (the latent or asymptomatic) and finally AIDS (1). When there is no treatment, HIV infection will progress from one stage to another and weaken the immune system during this process until it finally reaches AIDS. However, HIV medicines and antiretroviral therapy (ART) can stop HIV from advancing to AIDS (1). This essay presents the three stages of HIV infection in a way which shows when each stage begins and how it affects the body.…

    Human Immunodeficiency Virus, more commonly known as HIV, is a potentially fatal virus that is spread and contracted by humans. Unlike many other viruses that are transmitted HIV has the potential to hide from the human immune system, which prevents the virus from being destroyed. HIV does this by synthesizing a protein known as Nef. This protein aids the virus by convincing the host cell that the virus is actually part of the normal cellular waste, rather than displaying it on the surface of the host cell to be recognized and destroyed. Once the viral RNA is inside the host cell it does not reproduce immediately.…

    It’s important to take the treatment correctly and any possible side-effects. When a person’s CD4 count drops below, it’s possible that he/she have AIDS. Loss of CD4 cells makes it difficult for the body to fight infections and certain cancers. Having less HIV in the body protects the immune system. Anti-retroviral can not cure HIV, but it can help people with HIV live longer , healthier lives.…

    HIV significantly reduces the CD4 count level in the body making the body prone to opportunistic infections and cancer. Unlike other viruses, HIV cannot be completely removed from the body. Treatment needs to be continued throughout life. Antiretroviral Therapy (ART) can dramatically prolong the life of HIV patients, if taken correctly and regularly (Centers for Disease Control [CDC], 2016). HIV symptoms can be misleading, therefore, the best way to test for HIV is through testing available…

    Human Immune Deficiency means to lack the defense mechanisms necessary to fight against simple viruses like the common cold. The virus attacks the helper T cells in the body and prevents them from simulating B cells to secrete antibodies. It also prevents helper T cells from activating CD8 cells that are cytotoxic T cells which are antiviral cells. (van Baarle et al) HIV carries single-stranded RNA that, when coupled with reverse transcriptase, creates HIV DNA. When HIV enters the body, it attaches and fuses with the host cell.…
