What is Hiv and Aids about knowing the signs and symptoms of HIV (human immunodeficiency virus) before causing acquired immunodeficiency syndrome (AIDS) as the basis for writing this article
What is Hiv and Aids
HIV stands for human immunodeficiency virus. This virus can cause acquired immunodeficiency syndrome (AIDS) if not treated. Unlike some other viruses, the human body cannot get rid of HIV completely, even with treatment. So once you get HIV, you have it for the rest of your life.
HIV is a virus that spreads through certain body fluids that attack the immune system, especially CD4 cells, often called T cells. Over time, HIV can destroy so many cells that the body cannot fight off infections and diseases. This particular cell helps the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body. Damage to the immune system makes the body more difficult and difficult to fight infection and some other diseases. Opportunistic infections or cancer take advantage of a very weak immune system and signal that the person has AIDS.
AIDS is the most severe phase of HIV infection. People with AIDS have a severely damaged immune system so they get an increase in the number of serious illnesses, called opportunistic infections. Without treatment, progressing HIV gradually weakens your immune system and gets worse over time. The three stages of HIV infection are: (1) acute HIV infection, (2) clinical latency, and (3) AIDS (acquired immunodeficiency syndrome).
Here are three stages of HIV infection:
- Stage of Acute HIV Infection
Within two to four weeks after infection many people experience flu-like symptoms, often described as “the worst flu ever.” Symptoms can include fever, swollen glands, sore throats, rashes, muscle and joint aches and pains, and headaches. This is called “acute retro viral syndrome” (ARS) or “primary HIV infection,” and this is the body’s natural response to HIV infection. During this initial infection period, a large number of viruses are produced in your body. This virus uses CD4 cells to replicate and destroy it in the process. Therefore, your CD4 cell can go down quickly.
During the acute phase of HIV infection, you are at high risk of transmitting HIV to a couple or a couple because the level of HIV in your bloodstream is very high. For this reason, it is important to take steps to reduce your risk of transmission. During this stage, it may be very beneficial for your health to start ART.
- Clinical Latency Stage
After the acute phase of HIV infection, the disease moves to a stage called the “clinical latency” stage. “Latency” means the period in which a virus lives or develops in a person without causing symptoms. During the clinical latency stage, people infected with HIV have an experience any symptoms, or only mild symptoms. This stage is sometimes called “asymptomatic HIV infection” or “chronic HIV infection”. At this stage, the HIV virus continues to reproduce at very low levels, even it cannot be detected by standard laboratory tests. If you are on ART, you may live with clinical latency for decades and never develop AIDS because treatment helps keep the virus in check.
People at this symptom-free stage can still transmit HIV to others. For people not on ART, the clinical latency stage lasts an average of 10 years, but some people may also progress through this stage more quickly. As disease progression, the virus will begin to increase and your CD4 count will begin to decline. As this happens, you may begin to have constitutional symptoms of HIV when the level of virus increases in your body before you develop AIDS.
This is the stage of HIV infection that occurs when your immune system is severely damaged and you are susceptible to opportunistic infections. If your CD4 cell count falls below 200 cells per cubic millimeter of blood (200), you are considered to have AIDS. (In someone with a healthy immune system, CD4 cell counts range between 500 and 1,600). You are also considered to have AIDS if developing one or more opportunistic diseases, regardless of your CD4 count.
Without treatment, people with AIDS usually last about three years. Once you have a dangerous opportunistic disease, life-saving life expectancy falls to about one year. ART can help people with AIDS at diagnosis and help with lives. In the United States, most people with HIV do not develop AIDS because effective entrepreneurial treatment halts disease progression. People with HIV who are diagnosed early can have similar without to people who are not HIV. People living with HIV can develop at different rates, depending on a variety of factors, including their genetic makeup, how healthy they were before they became infected, how many viruses they were dealing with and their genetic characteristics, how quickly after they became infected. In addition, people diagnosed with HIV regularly perform medical tests, take their HIV medications as directed, and the health choices they make, such as the decision to eat healthy foods, exercise, and not smoke.
Is there any treatment for HIV?
There is no effective cure for HIV, but with proper medical care, HIV can tolerate it. Treatment for HIV is called entrepreneurial therapy (ART). ART helps control the virus so you can live a longer and healthier life and greatly reduce the risk of HIV transmission to others. Before the introduction of ART in the mid-1990s, people with HIV could progress to AIDS (the last stage of HIV infection) in recent years. Currently, someone who is diagnosed with HIV and the disease is much more advanced can live almost as long as someone who does not have HIV.
