HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have 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. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection.
HIV is a incurable disease that will lead to ACE. It lowers the body's ability to fight infection. The symptoms are chills, cold, fever, sores, nausea, and etc. HIV is contractable by saliva or blood. HIV is also a high risk of cause of death. First came to the U.S. First person who contracted it was known as patient 0.
