HIV virus infects and destroys white blood cells called CD4+ cells. The body can no longer defend itself against infection if too many CD4+ cells are destroyed.
What is HIV?
HIV, human immunodeficiency virus, attacks the body’s infection fighting cells, which makes a person vulnerable to diseases and infections. More specifically, HIV attacks the white blood cells called the CD4+ cells.
There is no effective cure for HIV, so once you contract the virus, it stays for life. There is, however, an effective treatment with HIV medicine. But, if left untreated, HIV can lead to AIDS, acquired immunodeficiency syndrome.
AIDS is the last stage of HIV. This occurs when the immune system of the body is badly damaged.
A person is said to have progressed to AIDS from HIV when their CD4 cell number falls below 200 per cubic ml of blood.
Therefore, HIV virus infects and destroys white blood cells called CD4+ cells. The body can no longer defend itself against infection if too many CD4+ cells are destroyed.
