All About Aids Essay Paper

AIDS (acquired immunodeficiency syndrome) is a syndrome caused by a virus called HIV (human immunodeficiency virus). The disease alters the immune system, making people much more vulnerable to infections and diseases. This susceptibility worsens if the syndrome progresses.

HIV is found throughout all the tissues of the body but is transmitted through the body fluids of an infected person (semen, vaginal fluids, blood, and breast milk).

In this article, we explain HIV and AIDS, their symptoms, causes, and treatments.

Overview

Overview

HIV is a virus that attacks immune cells called CD-4 cells, which are a subset of T cells. AIDS is the syndrome, which may or may not appear in the advanced stage of HIV infection.

HIV is a virus.

AIDS is a medical condition.

HIV infection can cause AIDS to develop. However, it is possible to contract HIV without developing AIDS. Without treatment, HIV can progress and, eventually, it will develop into AIDS in the vast majority of cases.

Causes

Causes


HIV can be passed from one person to another through blood-to-blood and sexual contact.

HIV is a retrovirus that infects the vital organs and cells of the human immune system.

The virus progresses in the absence of antiretroviral therapy (ART) - a drug therapy that slows or prevents the virus from developing.

The rate of virus progression varies widely between individuals and depends on many factors.

These factors include the age of the individual, the body's ability to defend against HIV, access to healthcare, the presence of other infections, the individual's genetic inheritance, resistance to certain strains of HIV, and more.

How is HIV transmitted?

Sexual transmission — it can happen when there is contact with infected sexual fluids (rectal, genital, or oral mucous membranes). This can happen while having sex without a condom, including vaginal, oral, and anal sex, or sharing sex toys with someone who is HIV-positive.

Perinatal transmission — a mother can transmit HIV to her child during childbirth, pregnancy, and also through breastfeeding.

Blood transmission — the risk of transmitting HIV through blood transfusion is extremely low in developed countries, thanks to meticulous screening and precautions. However, among people who inject drugs, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.

Symptoms

Symptoms

For the most part, the later symptoms of HIV infection are the result of infections caused by bacteria, viruses, fungi, and/or parasites.

These conditions do not normally develop in individuals with healthy immune systems, which protect the body against infection.

Early symptoms of HIV infection

Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.

The symptoms of early HIV infection may include:

  • fever
  • chills
  • joint pain
  • muscle aches
  • sore throat
  • sweats (particularly at night)
  • enlarged glands
  • a red rash
  • tiredness
  • weakness
  • unintentional weight loss
  • thrush

It is important to remember that these symptoms appear when the body is fighting off many types of viruses, not just HIV. However, if you have several of these symptoms and believe you could have been at risk of contracting HIV in the last few weeks, you should take a test.

Asymptomatic HIV

In many cases, after the initial symptoms disappear, there will not be any further symptoms for many years.

During this time, the virus carries on developing and damaging the immune system and organs. Without medication that stops HIV replicating, this process of slow immune depletion can continue, typically for an average of 10 years. The person living with HIV often experiences no symptoms, feels well, and appears healthy.

For people who are taking antiretrovirals and are rigidly compliant, this phase can be interrupted, with complete viral suppression. Effective antiretrovirals arrest on-going damage to the immune system.

Late-stage HIV infection

If left untreated, HIV weakens the ability to fight infection. The person becomes vulnerable to serious illnesses. This stage is known as AIDS or stage 3 HIV.

Symptoms of late-stage HIV infection may include:

  • blurred vision
  • diarrhea, which is usually persistent or chronic
  • dry cough
  • fever of above 100 °F (37 °C) lasting for weeks
  • night sweats
  • permanent tiredness
  • shortness of breath (dyspnea)
  • swollen glands lasting for weeks
  • unintentional weight loss
  • white spots on the tongue or mouth

During late-stage HIV infection, the risk of developing a life-threatening illness is much greater. Serious conditions may be controlled, avoided, and/or treated with other medications, alongside HIV treatment.

HIV and AIDS myths and facts

There are many misconceptions about HIV and AIDS. The virus CANNOT be transmitted from:

  • shaking hands
  • hugging
  • casual kissing
  • sneezing
  • touching unbroken skin
  • using the same toilet
  • sharing towels
  • sharing cutlery
  • mouth-to-mouth resuscitation
  • or other forms of "casual contact"
Diagnosis

Diagnosis

The CDC (Centers for Disease Control and Prevention) estimates that about 1 in every 8 HIV-positive Americans is unaware of their HIV status.

HIV blood tests and results

Diagnosis is made through a blood test that screens specifically for the virus. If HIV has been found, the test result is "positive." The blood is re-tested several times before a positive result is given.

If a person has been exposed to the virus, it is crucial that they get tested as soon as possible. The earlier HIV is detected, the more likely the treatment will be successful. A home testing kit can be used as well.

After infection with HIV, it can take from 3 weeks to 6 months for the virus to show up in testing. Re-testing may be necessary. If the moment an individual was most at risk of infection was within the last 6 months, they can have the test immediately. However, the provider will urge that another test is carried out within a few weeks.

Treatment

Treatment


The red ribbon is the worldwide symbol of support and awareness for people living with HIV.

There is currently no cure for HIV or AIDS. Treatments can stop the progression of the condition and allow most people living with HIV the opportunity to live a long and relatively healthy life.

Earlier HIV antiretroviral treatment is crucial — it improves quality of life, extends life expectancy, and reduces the risk of transmission, according to the World Health Organization's guidelines issued in June 2013.

Currently, there is no vaccine or cure for HIV, but treatments have evolved which are much more effective and better tolerated; they can improve patients' general health and quality of life considerably, in as little as one pill per day.

It is now established that, given the right treatment, someone living with HIV can reduce his or her viral load to such a degree that it is no longer detectable. After assessing a number of large studies, the CDC concluded that individuals who have no detectable viral load "have effectively no risk of sexually transmitting the virus to an HIV-negative partner."

This is referred to as undetectable = untransmittable (U=U).

Emergency HIV pills (post-exposure prophylaxis)

If an individual believes they have been exposed to the virus within the last 72 hours (3 days), anti-HIV medications, called PEP (post-exposure prophylaxis) may stop infection. The treatment should be taken as soon as possible after contact with the virus.

PEP is a treatment lasting 4 weeks, a total of 28 days. Monitoring for HIV will be continued after completion of the treatment.

Antiretroviral drugs

HIV is treated with antiretrovirals (ARVs). The treatment fights the HIV infection and slows down the spread of the virus in the body. Generally, people living with HIV take a combination of medications called HAART (highly active antiretroviral therapy) or cART (combination antiretroviral therapy).

There are a number of subgroups of antiretrovirals; these include:

Protease inhibitors

Protease is an enzyme that HIV needs to replicate. As the name suggests, protease inhibitors bind to the enzyme and inhibit its action, preventing HIV from making copies of itself. These include atazanavir/cobicistat (Evotaz), lopinavir/ritonavir (Kaletra), and darunavir/cobicistat (Prezcobix).

Integrase inhibitors

HIV needs the integrase enzyme to infect T cells. This drug prevents that step. Integrase inhibitors are often used in the first line of treatment because they are effective for many people, and cause minimal side effects. Integrase inhibitors include elvitegravir (Vitekta), dolutegravir (Tivicay), and raltegravir (Isentress)

Nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs)

These drugs, also referred to as "nukes," interfere with HIV as it tries to replicate and make more copies of itself. NRTIs include abacavir (Ziagen), lamivudine/zidovudine (Combivir), and emtricitabine (Emtriva)

Non-nucleoside reverse transcriptase inhibitors (NNRTIs)

NNRTIs work in a similar way to NRTIs, making it more difficult for HIV to replicate.

Chemokine co-receptor antagonists

Also known as CCRF, these drugs block HIV from entering cells. They are rarely used in America because other drugs are more effective.

Entry inhibitors

Entry inhibitors prevent HIV from entering T cells. Without access to these cells, HIV cannot replicate. As with chemokine co-receptor antagonists, they are rarely used in the United States.

A combination of these drugs will be used; the exact mix of drugs is adapted to each individual. HIV treatment is usually permanent and lifelong. HIV treatment is based on routine dosage. Pills must be taken on a regular schedule, every time. Each class of ARVs has different side effects, but some possible common side effects include:

  • nausea
  • fatigue
  • diarrhea
  • headache
  • skin rashes

Complementary or alternative medicine

Although widely used, alternative or complementary medications, such as herbal ones, have not been proven to be effective. According to some limited studies, mineral or vitamin supplements may provide some benefits in overall health. It is important to discuss these options with a healthcare provider because some of these options, even vitamin supplements, may interact with ARVs.

Prevention

To prevent contracting HIV, healthcare professionals advise precautions related to:

Condomless sex - having sex without a condom can put a person at risk of contracting HIV and other sexually transmitted infections (STIs). HIV can be transmitted by having sex without a condom (vaginal, oral, and/or anal sex). It can also be transmitted by sharing sex toys with someone infected with HIV. Condoms should be used with every sexual act.

Drug injection and needle sharing - intravenous drug use is an important factor in HIV transmission in developed countries. Sharing needles can expose users to HIV and other viruses, such as hepatitis C. Strategies such as needle-exchange programs are used to reduce the infections caused by drug abuse. If someone needs to use a needle, it must be a clean, unused, unshared needle.

Body fluid exposure - exposure to HIV can be controlled by employing precautions to reduce the risk of exposure to contaminated blood. Healthcare workers should use barriers (gloves, masks, protective eyewear, shields, and gowns) in the appropriate circumstances. Frequent and thorough washing of the skin immediately after coming into contact with blood or other bodily fluids can reduce the chance of infection.

Pregnancy - some ARVs can harm the unborn child. But an effective treatment plan can prevent HIV transmission from mother to baby. Precautions have to be taken to protect the baby's health. Delivery through cesarean section may be necessary.

HIV-infected mothers can pass the virus through their breast milk. However, if the mother is taking the correct medications, the risk of transmitting the virus is greatly reduced. It is important for a new mother to discuss the options with a healthcare provider.

Education - teaching people about known risk factors is vital.

Management

Management

Adherence - HIV treatment is effective if medication is taken as prescribed. Missing even a few doses may jeopardize the treatment. A daily, methodical routine should be programmed to fit the treatment plan around the individual's lifestyle and schedule. A treatment plan for one person may not be the same treatment plan for another. "Adherence" is sometimes known as "compliance".

General Health - it is crucial to take medication correctly and take steps to avoid illness. People living with HIV should seek to improve their general health by regularly exercising, eating healthfully, and not smoking.

Additional precautions - people living with AIDS should be extra cautious to prevent exposure to infection. They should be careful around animals and avoid coming into contact with cat litter, animal feces, and birds, too. Meticulous and regular washing of hands is recommended. These precautions are not as necessary while taking therapy.

Long-term condition - HIV is a lasting condition, so it is important to be in regular contact with the healthcare team. The treatment plan will be regularly reviewed.

Psychological - common misconceptions about AIDS and HIV are diminishing. However, the stigma of the condition persists in many parts of the world. People who are living with HIV may feel excluded, rejected, discriminated, and isolated.

Being diagnosed with HIV can be very distressing, and feelings of anxiety or depression are common. If you feel anxious or have symptoms of depression, seek medical help immediately.

Hiv/Aids Research Paper

HIV/AIDS

Throughout history, few illnesses have carried as much significance as Acquired Immune Deficiency Syndrome or AIDS. Similar human catastrophes have presented in our history such as, bubonic plague, leprosy and tuberculosis. All of these dreaded sicknesses have caused pain and suffering across cultures. Pain is associated with the physical distress of the patient, suffering is culturally distinctive, it describes the affliction of the human spirit and how community members cope with it. AIDS has given moral "do-gooders" a ripe opportunity to condemn others for behaviors which do not coincide with their perceived values. Globally, Americans have been blamed for creating the virus and spreading the disease worldwide. AIDS has created a symbol for suffering across the globe and this term paper demonstrates two different approaches to the care and concern for those afflicted with the HIV/AIDS virus.

Acquired Immune Deficiency Syndrome or AIDS, is a disease entity that has been identified since 1981 among homosexual men and intravenous drug users, witch is characterized by severe weight loss, night sweats, swollen lymph nodes and some AIDS victims develop severe dementia. AIDS is caused by infection with the human immunodeficiency virus (HIV), The virus commonly enters the body via blood transfusion or blood contaminates needles and through sexual contact. The virus attacks selected cells in the immune system and produces defects in function. This leaves the body open to an invasion by various infections; therefore, called opportunistic diseases and the development of unusual cancers. The virus also tends to reach certain brain cells. Since the first AIDS cases were reported in 1981, through mid-1991, more than 190,000 AIDS cases and more than 120,000 deaths had been reported in about 162 countries worldwide. Sub-Saharan Africa in particular appears to suffer a heavy burden of this illness. So far there is no cure or vaccine that exists. Further study of AIDS patients revealed marked depletion of certain white blood cells, called T4 lymphocytes. Then, in 1983, a T-celllymphotropic virus was separately discovered by Robert Gallo at the U.S National Institutes of Health and Luc Mon tagnier at France's Pasteur Institute Modes of Transmission Researchers.

In addition, in the early 1990's, AIDS was mostly only infecting homosexual men. Now, it has spread to men, women and children of all ages and sexualities. Homosexual men are at the highest risk for HIV/AIDS. Today, more than half of all new infections strike population under the age of 25, primary women, infant and children death rates have risen sharply. If you are not in a monogamous relationship and/or you are not sure if your partner is HIV positive, you can reduce the risk of getting the virus...
