What Is Stage 3 Hiv

What Is A Latent Hiv Reservoir

3 HIV Stages Explained

A latent HIV reservoir is a group of immune system cells in the body that are infected with HIV but are not actively producing new virus.

HIV attacks immune system cells in the body and uses the cells own machinery to make copies of itself. However, some HIV-infected immune cells go into a resting or latent state. While in this resting state, the infected cells do not produce new virus. HIV can hide inside these cells for years, forming a latent HIV reservoir but, at any time, cells in the latent reservoir can become active again and start making more virus.

To find out more about how HIV attacks cells, read the HIV Life Cycle fact sheet from HIVinfo.

How Is Hiv Transmitted

Human immunodeficiency virus is transmitted by coming in direct contact with certain body fluids of the person infected with HIV. These fluids are as follows

  • Blood
  • Receiving blood products that are contaminated with HIV
  • Getting stuck with an HIV-contaminated needle

Hence, taking precautions either while having sex or sharing a needle is the best way to prevent HIV.

Clinical Latency Stage Of Hiv Infection

The symptoms during ARS may last for a few weeks, according to the National Institutes of Health.

After this point, the infection progresses to the clinical latency stage, a period during which the virus reproduces at very low levels, but it is still active.

Also known as asymptomatic HIV infection or chronic HIV infection, the clinical latency stage typically causes no HIV-related symptoms.

For people who are not taking any anti-retroviral medication for their infection, the clinical latency stage lasts for 10 years, on average, but it may progress quicker.

ART, though, can keep the virus from growing and multiplying, prolonging the clinical latency state for several decades.

It’s important to note that people living with HIV in the clinical latency stage are contagious and can still transmit the virus to other people. But, as the CDC notes, people who take ART exactly as prescribed and maintain an undetectable viral load have effectively no risk of transmitting HIV to their HIV negative-partner through sex.

Symptoms And Stages Of Hiv Infection

FAST FACTS

  • There are three stages of HIV infection. The symptoms vary in type and severity from person-to-person.
  • Stage 1 after initial infection can feel like flu but not everyone will experience this.
  • Stage 2 is when many people start to feel better and may last for 10 years or more. During this time a person may have no symptoms.
  • Stage 3 is when a persons immune system is very badly damaged and can no longer fight off serious infections and illnesses.
  • The earlier a person is diagnosed with HIV and starts treatment, the better their health will be over time.
  • Some people dont get any symptoms during stages 1 and 2, and may not know they have the virus, but they can still pass on HIV.

The signs of HIV infection can vary in type and severity from person-to-person, and some people may not have any symptoms for many years.

The stages below describe how HIV infection progresses in the body if it is left untreated. Without antiretroviral treatment for HIV, the virus replicates in the body and causes more and more damage to the immune system.

However with effective treatment, you can keep the virus under control and stop it from progressing. This is why its important to start treatment as soon as possible after testing positive.

Stage : Seroconversion Illness

The primaryinfection stage only lasts for a number of weeks, during which the person maysuffer from flu-like symptoms such as fever, upset stomach, sore throat ormuscle pain. About one fifth of people would suffer enough to see a doctor butHIV is rarely diagnosed on this alone.

At this point, the immune system is starting to react to the virus by producing HIV antibodies and cytotoxic lymphocytes a process known as seroconversion. A third generation HIV test carried out before this process is complete may be negative or inconclusive.

Stage : Asymptomatic Stage

Aside from swollenglands, a person is largely symptomless at this stage and often starts to feelbetter. On average, this asymptomatic stage lasts for around ten years, but canlast up to 15 years. HIV antibodies can now be found in the blood and thereforean HIV test will give a positive result.

HIV is active withinthe lymph nodes at this time, infecting new cells and making copies of itself. Aviral load test measures the small amount of HIV which gets away from the lymphnodes. This information is very important in the treatment of HIV.

What Is The Connection Between The Hiv Life Cycle And Hiv Medicines

Antiretroviral therapy is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines every day. HIV medicines protect the immune system by blocking HIV at different stages of the HIV life cycle.

HIV medicines are grouped into different drug classes according to how they fight HIV. Each class of drugs is designed to target a specific step in the HIV life cycle.

Because an HIV regimen includes HIV medicines from at least two different HIV drug classes, ART is very effective at preventing HIV from multiplying. Having less HIV in the body protects the immune system and prevents HIV from advancing to AIDS.

ART cant cure HIV, but HIV medicines help people with HIV live longer, healthier lives. HIV medicines also reduce the risk of HIV transmission .

How Do I Know If I Have Hiv

The only way to know for sure if you have HIV is to get tested. Testing is relatively simple. You can ask your health care provider for an HIV test. Many medical clinics, substance abuse programs, community health centers, and hospitals offer them too. You can also buy a home testing kit at a pharmacy or online.

To find an HIV testing location near you, use the HIV Services Locator.

HIV self-testing is also an option. Self-testing allows people to take an HIV test and find out their result in their own home or other private location. You can buy a self-test kit at a pharmacy or online. Some health departments or community-based organizations also provide self-test kits for free.

Read the U.S. Food and Drug Administrations fact sheet on the OraQuick In-Home HIV Test, the only FDA-approved in-home HIV test.

The coronavirus pandemic has made it more difficult for some people to access traditional places where HIV testing is provided. Self-testing allows people to get tested for HIV while still following stay-at-home orders and social distancing practices. Ask your local health department or HIV service organization if they offer self-testing kits.

Chronic Hiv Infection With Antiretroviral Treatment

stage 3 of HIV

If you take effective HIV treatment, you can live with HIV as a chronic, manageable condition. A chronic health condition is one which continues for a long period of time.

This stage is not included in most descriptions of the stages of infection, which only describe disease progression in the absence of treatment.

However, most people living with HIV who have access to good healthcare are living with HIV as a chronic condition and will continue to do so for the rest of their lives. They are unlikely to fall ill or die as a direct result of HIV.

In order to reach this stage and to remain in it, you need to take HIV treatment and continue to take it, on an ongoing basis. These medications reduce levels of HIV in your body and strengthen the immune system. This usually prevents the symptoms and opportunistic infections described above from occurring.

One of the benefits of effective HIV treatment is that is stops HIV from being passed on. Treatment drastically reduces the amount of HIV in body fluids to the point where there is not enough HIV to transmit the virus to sexual partners.

The chronic infection phase can last for decades. People who start HIV treatment as soon as possible, are able to stick with it and have access to good healthcare are likely to have a similar life expectancy to their peers who dont have HIV.

How To Prevent Hiv From Progressing

The most effective way is to take antiretroviral medication as soon as possible and to do so consistently as prescribed.

Antiretroviral therapy keeps the immune system healthy and reduces the risk of transmitting the virus to virtually zero.

The sooner a person receives a diagnosis, the sooner they can begin treatment. Early treatment can improve the persons outlook and lower the risk of the virus passing on to others.

Aids Is The Final Stage

Controlling HIV with medications is crucial to both maintaining quality of life and helping prevent progression of the disease. Stage 3 HIV, also known as AIDS, develops when HIV has significantly weakened the immune system.

According to the CDC National Prevention Information Network, CD4 levels give one indication that HIV has progressed to its final stage. CD4 levels decreasing below 200 cells per cubic millimeter of blood is considered a sign of AIDS. A normal range is considered 500 to 1,600 cells/mm3.

AIDS can be diagnosed with a blood test to measure CD4. Sometimes its also determined simply by a persons overall health. In particular, an infection thats rare in people who dont have HIV may indicate AIDS. Symptoms of AIDS include:

  • persistent high fevers of over 100°F
  • pneumonia

AIDS is the final stage of HIV. According to AIDSinfo, it takes at least 10 years without treatment for most people with HIV to develop AIDS.

At that point, the body is susceptible to a wide range of infections and cant effectively fight them off. Medical intervention is necessary to treat AIDS-related illnesses or complications that can otherwise be fatal. Without treatments, the CDC estimates the average survival rate to be three years once AIDS is diagnosed. Depending on the severity of their condition, a persons outlook may be significantly shorter.

How Does Hiv Affect A Person In The Long Term

Though the outlook has gotten much better for those with HIV, there are still some long-term effects that they might experience.

As time passes, people living with HIV may begin to develop certain side effects of treatment or HIV itself.

These may include:

The body may also undergo a shift in how it processes sugars and fats. This can lead to having more fat in certain areas of the body, which can change the bodys shape. However, these physical symptoms are more common with older HIV medications. Newer treatments have far fewer, if any, of these symptoms affecting physical appearance.

If treated poorly or left untreated, HIV infection can develop into stage 3 HIV, or AIDS.

A person develops stage 3 HIV when their immune system is too weak to defend their body against infections. A healthcare provider will likely diagnose stage 3 HIV if the number of certain white blood cells in an HIV-positive persons immune system drops below 200 cells per mL of blood.

Life expectancy is different for every person living with stage 3 HIV. Some people may die within months of this diagnosis, but the majority can live fairly healthy lives with regular antiretroviral therapy.

Who Disease Staging System For Hiv Infection And Disease

Common Symptoms for Each Stage of HIV : Human N Health

WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization and updated in September 2005. It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIVdisease. Most of these conditions are opportunistic infections that are easily treated in healthy people. The staging system is different for adults and adolescents and children.

Stage I: HIV disease is asymptomatic and not categorized as AIDS.

Stage II: include minor mucocutaneous manifestations and recurrent upper respiratory tract infections.

Stage III: includes unexplained chronic diarrhea for longer than a month, severe bacterial infections and pulmonary tuberculosis.

Stage IV: includes toxoplasmosis of the brain, candidiasis of the esophagus, trachea, bronchi or lungs and Kaposi’s sarcoma these diseases are used as indicators of AIDS.

How Will I Know If I Have Kidney Disease

Most people with early kidney disease do not have symptoms. The best way to find out is to be tested for it. There are two simple tests to check for kidney disease.

  • Urine Test called ACR. ACR stands for “albumin-to-creatinine ratio.” Your urine will be tested for albumin. Albumin is a type of protein. Your body needs protein. However, it should be in the blood, not the urine. Having protein in your urine may mean that your kidneys are not filtering your blood well enough. This can be a sign of early kidney disease. If your urine test comes back “positive” for protein, the test should be repeated to confirm the results. Three positive results over three months or more is a sign of kidney disease.
  • Blood Test to estimate your GFR. Your blood will be tested for a waste product called creatinine. Creatinine comes from muscle tissue. When the kidneys are damaged, they have trouble removing creatinine from your blood. Testing for creatinine is only the first step. Next, your creatinine result is used in a math formula with your age, race, and sex to find out your glomerular filtration rate . Your GFR number tells your healthcare provider how well your kidneys are working.
  • What Are The 3 Stages Of Hiv When Does Hiv Infection Transition To Aids

    There are 3 stages of HIV infection.

    • Stage 1: Flu-like symptoms after initial HIV infection
    • Stage 2: Clinically latency may last for 10 or more years in some individuals
    • Stage 3: After HIV reactivation and/or HIVs progressive attack on the immune system, the damaged immune system has a reduced or an inability to protect the individual from serious infections and other illnesses. This stage is termed AIDS. In this stage, lab testing reveals high viral loads and CD4 counts < 200 cells/mm3.

    Which Is Worse Hiv Or Aids

    AIDS is the last and most advanced stage of HIV. A person is considered to have progressed into AIDS when the following occurs:

    • CD4 cell count drops below 200
    • Develop one or more opportunistic infections

    AIDS is characterized by the occurrence of severe illnesses, referred to as opportunistic infections. These infections tend to occur more often in those with AIDS and affect people with weakened immune systems more severely than people with healthy immune systems. Some of the most common opportunistic infections include:

    • Herpes simplex virus
    • Thrush
    • Toxoplasmosis

    If you are experiencing symptoms of early-stage HIV and believe you may have been exposed to the virus, its important to find out more. This can be done by taking a test with your doctor or from home with an at-home lab test.

    • You should also consider getting tested if:
    • You become sexually active
    • You have had unprotected sex
    • You are experiencing symptoms of a sexually transmitted infection
    • You are entering into a new sexual relationship
    • You have received a notification from a previous partner that they are infected

    What Is The Hiv Life Cycle

    Fact 7: Stages of HIV

    HIV attacks and destroys the CD4 cells of the immune system. CD4 cells are a type of white blood cell that play a major role in protecting the body from infection. HIV uses the machinery of the CD4 cells to multiply and spread throughout the body. This process, which is carried out in seven steps or stages, is called the HIV life cycle.

    Do Hiv Medicines Work Against Latent Hiv Reservoirs

    HIV medicines prevent HIV from multiplying, which reduces the amount of the virus in the body . Because the HIV-infected cells in a latent reservoir are not producing new copies of the virus, HIV medicines have no effect on them.

    People with HIV must take a daily combination of HIV medicines to keep their viral loads low. If a person stops taking their HIV medicines, the infected cells of the latent reservoir can begin making HIV again and the person’s viral load will increase. That is why it is important to continue taking HIV medicines every day as prescribed, even when viral load levels are low.

    Latency Causes A Break In Symptoms

    After initial exposure and possible primary infection, HIV may transition into a stage called clinically latent infection. Its also referred to as asymptomatic HIV infection due to a noticeable lack of symptoms. This lack of symptoms includes possible chronic symptoms.

    According to HIV.gov, latency in HIV infection can last for 10 or 15 years. This doesnt mean that HIV is gone, nor does it mean that the virus cant be transmitted to others. Clinically latent infection may progress to the third and final stage of HIV, also referred to as AIDS.

    The risk for progression is higher if a person with HIV isnt receiving treatment, such as antiretroviral therapy. Its important to take prescribed medications during all stages of HIV even if there arent any noticeable symptoms. There are several medications used for HIV treatment.
