What is the full form of aids

Diagnosis HIV can be diagnosed through blood or saliva testing. Available tests include: • Antigen/antibody tests. These tests usually involve drawing blood from a vein. Antigens are substances on the HIV virus itself and are usually detectable — a positive test — in the blood within a few weeks after exposure to HIV. Antibodies are produced by your immune system when it's exposed to HIV. It can take weeks to months for antibodies to become detectable. The combination antigen/antibody tests can take 2 to 6 weeks after exposure to become positive. • Antibody tests. These tests look for antibodies to HIV in blood or saliva. Most rapid HIV tests, including self-tests done at home, are antibody tests. Antibody tests can take 3 to 12 weeks after you're exposed to become positive. • Nucleic acid tests (NATs). These tests look for the actual virus in your blood (viral load). They also involve blood drawn from a vein. If you might have been exposed to HIV within the past few weeks, your health care provider may recommend NAT. NAT will be the first test to become positive after exposure to HIV. Talk to your health care provider about which HIV test is right for you. If any of these tests are negative, you may still need a follow-up test weeks to months later to confirm the results. Tests to stage disease and treatment If you've been diagnosed with HIV, it's important to find a specialist trained in diagnosing and treating HIV to help you: • Determine whether you need additional tes...

Ask Free Question Symptoms of HIV Early Stage * Within 2-4 week after HIV infection many but not all experience flu like symptoms which may last from few days to several weeks This is called Acute Retroviral Syndrome. Some patients do not experience any symptoms for 10 years or more. * The symptoms are fever, swollen gland, sorethroat, skin rash * Fatigue, headache, muscle and joint pain Clinical Latency Stage * During this stage HIV patients have no symptoms. * If the patient takes ART (Anti Retroviral treatment) at this stage he can stay healthy and live in this stage for several decades. Without treatment, this stage lastsfor 10 years and he develops symptoms of AIDS after 10 years. AIDS Stage If the patient has not taken ART in the clinical latency stage, he develops AIDS after 10 years The symptoms of AIDS are * Rapid weight loss * Recurrent fever or profuse night sweat * Extreme unexplained tiredness * Prolonged swelling of the lymph nodes in armpit, neck and groin * Uncontrolled diarrhoea lasting for more than a week * Sores of mouth, anus and genitalia * Red, brown, pink or purplish rashes under skin, inside of mouth, nose, eye lid * Pneumonia * Memory loss, depression and other neurological disorder Suggestions offered by doctors on Lybrate are of advisory nature i.e., for educational and informational purposes only.

The main cellular target of HIV is a gp120. The gp120 protein binds to a molecule called CD4 on the surface of the helper T cell, an event that initiates a complex set of reactions that allow the HIV genetic information into the cell. Entry of HIV into the host cell also requires the participation of a set of cell-surface proteins that normally serve as receptors for Once the CD4 count, provides a good indication of the status of the immune system. Physicians also measure the amount of virus in the bloodstream—i.e., the viral load—which provides an indication of how fast the virus is replicating and destroying helper T cells. 44 Questions from Britannica’s Most Popular Health and Medicine Quizzes The genome of HIV mutates at a very high rate, and the virus in each infected individual is thus slightly different. The genetic mechanisms that underlie the individual variation have been investigated through approaches based on genome sequencing. The HIV-1 genome in 2009 was the first HIV genome to be sequenced in its entirety. Prior to that achievement, the ability of HIV RNA to fold into highly Sequencing revealed that variation occurs throughout the HIV genome but is especially pronounced in the gene encoding the gp120 protein. By constantly changing the structure of its predominant surface protein, the virus can avoid recognition by antibodies produced by the immune system. Sequencing also has provided useful insight into genetic factors that influence viral activity. Knowle...

Human immunodeficiency virus (HIV) is the virus that causes acquired immune deficiency syndrome (AIDS). HIV weakens your immune system by destroying your T-cells until you are unable to fight off even minor illnesses. You can have HIV without any symptoms. Getting tested and starting treatment early gives you the best chance of living a long life. Overview What is HIV? HIV stands for human immunodeficiency virus. HIV infects and destroys cells of your immune system, making it hard to fight off other diseases. When HIV has severely weakened your immune system, it can lead to acquired immunodeficiency syndrome (AIDS). Because HIV works backward to insert its instructions into your DNA, it is called a retrovirus. What is AIDS? AIDS is the final and most serious stage of an HIV infection. People with AIDS have very low counts of certain white blood cells and severely damaged immune systems. They may have additional illnesses that indicate that they have progressed to AIDS. Without treatment, HIV infections progress to AIDS in about 10 years. What’s the difference between HIV and AIDS? The difference between HIV and AIDS is that HIV is a virus that weakens your immune system. AIDS is a condition that can happen as a result of an HIV infection when your immune system is severely weakened. You can’t get AIDS if you aren’t infected with HIV. Thanks to treatment that slows down the effects of the virus, not everyone with HIV progresses to AIDS. But without treatment, almost all peo...
