- The human immunodeficiency virus is the cause of HIV infection and the acquired immunodeficiency syndrome (AIDS). HIV belongs to a family of organisms known as retroviruses. Once someone acquires the virus, it attaches to and enters human cells, especially cells known as CD4 T-cells, macrophages, and dendritic cells.

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.

Causes HIV is not passed on easily from one person to another. The virus does not spread through the air like cold and flu viruses. HIV lives in the blood and in some body fluids. To get HIV, one of these fluids from someone with HIV has to get into your blood. The body fluids that contain enough HIV to infect someone are: 1  semen. 2  vaginal fluids, including menstrual blood. 3  breast milk. 4  blood. 5  lining inside the anus.

- The human immunodeficiency virus (HIV) is one of the most serious, deadly diseases in human history. HIV causes a condition called acquired immunodeficiency syndrome — better known as AIDS. HIV destroys a type of defense cell in the body called a CD4 helper lymphocyte (pronounced: LIM-foe-site). These lymphocytes are part of the body's immune system, the defense system that fights infections.

HIV/AIDS HIV/AIDS. Human immunodeficiency virus (HIV) infection (HIV) occurs when the virus invades cells in the immune system and uses them to make more HIV cells. HIV is a retrovirus, meaning it needs host cells to replicate. The host cells it uses are CD4, or helper T, cells, which initiate the body’s response to infection.

- HIV, or human immunodeficiency virus, causes AIDS. HIV can be transmitted through blood transfusion, sex, contaminated hypodermic needles, childbirth, and breastfeeding. HIV destroys the important cells in the human body that fight disease and infection. While the immune system is capable of fighting many other viruses, like the common flu, it can’t fight HIV.

HIV (like other viruses) is harmless after antibody immunity. 2. HIV does not kill T-Cells it infects. 3. HIV does not infect enough T-Cells to cause Aids. 4. HIV has no AIDS causing gene. 5. There is no such thing as a slow virus.

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. As the leading U.S. government institute for HIV/AIDS research, NIAID is committed to conducting the research necessary to successfully end the fight against HIV/AIDS.

HIV The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.nfection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk.

WHAT IS AIDS? AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make antibodies, special immune molecules the body makes to fight HIV. Tests for HIV look for these antibodies in your blood or mouth lining. If you have them in your blood, it means that you have HIV infection. Fact Sheet 102 has more information on HIV testing. Being HIV-positive, or having HIV disease, is not the same as having AIDS.

HIV and AIDS Human immunodeficiency virus, or HIV, is the virus that causes acquired immune deficiency syndrome (AIDS). The virus weakens a person's ability to fight infections and cancer.People with HIV are said to have AIDS when they develop certain infections or cancers or when their CD4 count is less than 200.CD4 (T-cell) count is determined by a blood test in a doctor's office.IDS is the more advanced stage of HIV infection. When the immune system CD4 cells drop to a very low level, a person's ability to fight infection is lost.
