How HIV Affects the Body Human immunodeficiency virus (HIV) is a virus that causes the condition acquired immunodeficiency syndrome (AIDS). The virus attacks a specific type of immune system cell in the body, known as CD4 helper lymphocyte cells. HIV destroys these cells, making it harder for your body to fight off other infections. When you have HIV, even a minor infection (like a cold) can be much more severe because your body has difficulty healing. HIV is transmitted through contact with the following bodily fluids: blood ; breast milk ; semen ; vaginal fluid

How HIV Damages the Immune System In HIV, viral RNA has a protein called reverse transcriptase that is crucial for viral replication inside T cells, white blood cells that help coordinate activities of the immune system. (The function of reverse transcriptase, which means writing backwards, will be explained later when we discuss how HIV infects T cells.)

Comprehensive, up-to-date information on HIV/AIDS treatment and prevention from the University of California San Francisco HIV stands for Human Immunodeficiency Virus. HIV is a virus. Some viruses, such as the ones that cause the common cold or the flu, stay in the body only for a few days. Some viruses, such as HIV, never go away. When a person becomes infected with HIV, that person becomes HIV positive and will always be HIV positive.

What Are HIV and AIDS? About HIV/AIDS. Language: HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections.

Could HIV kill the person? The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome). People with AIDS have a low number of CD4+ cells and get infections or cancers that rarely occur in healthy people. These can be deadly.

White blood cells are an important part of the immune system.ou can get HIV from contact with infected blood, semen, or vaginal fluids. 1  Most people get the virus by having unprotected sex with someone who has HIV. 2  Another common way of getting it is by sharing drug needles with someone who is infected with HIV.

Treatment Decisions for HIV: Entire Section CD4 cells play a major role in helping your immune system work properly. HIV causes disease by killing off CD4 cells. It does this by infecting the cells and turning them into virus factories, a process that kills the cell. A test called the CD4 count can tell you how many CD4 cells you have.

- The immune system does try to fight HIV infection. It produces antibodies to do this. But they’re not very effective without the CD4 cells to organise them. Normally the body's immune system would fight off an infection, but HIV prevents the body’s immune system from working properly.

Overview 1 If your immune system weakens, the virus resurfaces — causing damage to your eyes, digestive tract, lungs or other organs.  Candidiasis. Candidiasis is a common HIV-related infection. It causes inflammation and a thick, white coating on the mucous membranes of your mouth, tongue, esophagus or vagina.

- HIV disrupts this process by directly infecting the helper T-cells. Your initial immune response does get rid of a great deal of HIV, but some of it manages to survive and infect these important cells. Once the infected helper T-cells are activated, they work to create new viruses instead of doing the job they are supposed to do in your immune system. In addition, many helper T-cells are destroyed in the HIV replication process. For more information, see NIAID's The Immune System.

What are HIV and AIDS? If HIV is left untreated, it may take up to 10 or 15 years for the immune system to be so severely damaged it can no longer defend itself at all. However, the speed HIV progresses will vary depending on age, health and background. Basic facts about HIV. HIV stands for human immunodeficiency virus.

What is HIV? All viruses must infect living cells to reproduce. HIV takes over certain immune system cells that are supposed to defend the body. These cells are called CD4 cells, or T cells. When HIV takes over a CD4 cell, it turns the cell into a virus factory. It forces the cell to produce thousands of copies of the virus. These copies infect other CD4 cells. Infected cells don't work well and they die early.

How HIV infects the body and the lifecycle of HIV The HIV virus attacks a type of white blood cell called T-helper cells (also called CD4 cells). These cells are important when it comes to having a healthy immune system as they help us fight off diseases and infections. HIV cannot grow or reproduce on its own.

- In doing so, the virus destroys the ability of the infected cells to do their job in the immune system. The body then loses the ability to fight many infections. When a person with HIV has an extremely low number of CD4 cells or certain rare infections, doctors call this stage of disease AIDS.
