- 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.

The HIV Life Cycle Although HIV can infect a number of cells in the body, the main target is an immune cell called a lymphocyte, more specifically a CD4 helper cell, a type of T-cell. T-cells are an important part of the immune system because they help facilitate the body's response to many common but potentially fatal infections.

HIV and AIDS How Does HIV and AIDS Cause Illness? HIV attacks and destroys a type of white blood cell called a CD4 cell, commonly called the T-cell. This cell's main function is to fight disease. When a person's CD4 cell count gets low, they are more susceptible to illnesses. AIDS is the more advanced stage of HIV infection.

HIV/AIDS HIV/AIDS. HIV, or human immunodeficiency virus, is the virus that causes AIDS (Acquired Immunodeficiency Syndrome). HIV attacks the immune system by destroying CD4 positive (CD4+) T cells, a type of white blood cell that is vital to fighting off infection. The destruction of these cells leaves people living with HIV vulnerable to other infections, diseases and other complications.

What Are HIV and AIDS? HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get other infections or infection-related cancers.

Immune Restoration Immune restoration means repairing the damage done to the immune system by HIV. In a healthy immune system, there is a full range of CD4 cells (T-cells, see Fact Sheet 124) that can fight different diseases. As HIV disease progresses, the number of CD4 cells drops. The first CD4 cells that HIV attacks are the ones that specifically fight HIV. Some types of CD4 cells can disappear, leaving gaps in the immune defenses. Immune restoration looks for ways to fill these gaps. A healthy immune system can fight off opportunistic infections (OIs, see Fact Sheet 500).

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.

- How HIV/AIDS overwhelms the body. HIV attacks and kills a type of immune system cell known as T lymphocytes. These T cells are crucial for killing other cells in the body that have been infected with germs. Without T cells, other immune system cells, such as antibody-making B cells, can't work properly.

How HIV Affects the Body Not only does HIV attack CD4 cells, it also uses the cells to make more of the virus. When the virus has destroyed a certain number of CD4 cells, doctors will call this stage AIDS. A person with AIDS is very vulnerable to infections, such as pneumonia.

individualism Use individualism in a sentence. Our country's laws are based upon the Founders' collective belief in the principles of individualism, a statement which seems to be ironic. Often teenagers express their individualism by dying their hair bright colors or getting piercings in various parts of their bodies.

HIV/AIDS Treatment with Garlic The HIV virus attacks the immune system and can effectively destroy its ability to fight diseases. When the virus has destroyed too many of the immune system’s white blood cells, the body succumbs to all kinds of invasive infections and diseases, including pneumonia, Kaposi’s sarcoma, herpes, meningitis, tuberculosis, cancer and others.

What does HIV destroy in the human body? Not exactly. HIV infects T cells but does not destroy them directly; it is the body's own autoimmune reaction against the infected T cells that destroys them. Edit Share to:

- AIDS is caused by the human immunodeficiency virus, or HIV. By killing or damaging cells of the body's immune system, HIV progressively destroys the body's ability to fight infections and certain cancers. People diagnosed with AIDS may get life-threatening diseases called opportunistic infections.

What Are HIV and AIDS? Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. Learn more about the stages of HIV and how to know whether you’re infected. What Is HIV? HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS, if not treated. Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment. So once you get HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get other infections or infection-related cancers.

HIV Testing Human immunodeficiency virus (HIV) is the virus that causes acquired immune deficiency syndrome (AIDS). HIV destroys the body's immune system and eventually leads to AIDS. People with AIDS develop many diseases and opportunistic infections (such as pneumonia, tuberculosis, cancer, and skin infections) that may ultimately lead to death. Prevention is critical. There is no cure for HIV/AIDS, but currently, there are effective treatments that can drastically slow the disease process.

AIDS and HIV Infection T-lymphocytes help the immune system perform its important task of fighting disease in the body caused by invading germs. As a result of HIV infection, the immune system becomes weakened and the body has trouble battling certain infections caused by bacteria, viruses, parasites, and fungi.

- Human immunodeficiency virus (HIV) infects the cells of the immune system. In particular, HIV attacks and destroys the T helper lymphocytes, or T-cells, which are crucial to the immune system and immune response.These cells are also called CD4-positive lymphocytes because HIV uses the protein CD4, present on the surface of the cell, to attach itself and pry its way into the cell.) Each day, your body produces millions of CD4+ T-cells to help maintain your immunity and fight off invading viruses and germs.

- Once enough of those cells have been destroyed by HIV, the person develops AIDS. We currently do not have a cure for any virus. There are treatments out there for various viruses, including HIV, which help, but ultimately the immune system is the only thing that can rid the body of a virus.

What is the difference between HIV and AIDS? HIV, or the human immunodeficiency virus, is the virus that causes AIDS (acquired immunodeficiency syndrome). HIV destroys the body's immune system by killing the blood cells that fight infection. Once HIV destroys a substantial proportion of these cells, the body's ability to fight off and recover from infections is compromised. This advanced stage of HIV infection is known as AIDS.

HIV/AIDS HIV infection also increases the risk of certain cancers, illnesses of the brain and nerves, body wasting, and death. The range of symptoms and illnesses that can happen when HIV infection severely weakens the body's immune defenses is called acquired immunodeficiency syndrome or AIDS.

Can you explain AIDS and how it affects the immune system? How does HIV become AIDS? HIV is a unique human RNA virus, capable of infecting cells of the immune system. Specifically, HIV targets T helper cells (CD4 cells), leading to the eventual death of the cell. CD4 cells are vital players in the regulation of immune responses to invading microorganisms. In an untreated person, 10 billion to 100 billion new viruses are produced per day.
