What is the primary function of Human Immunodeficiency Virus (HIV) in the body?

The primary function of Human Immunodeficiency Virus (HIV) in the body is to disable the body's immune system. HIV specifically targets and infects CD4+ T cells, which are crucial for the immune response. By attacking these cells, HIV progressively weakens the immune system, making it difficult for the body to fight off infections and diseases. Over time, if untreated, this can lead to acquired immunodeficiency syndrome (AIDS), a condition characterized by severe immune deficiency. This is a significant concern since a compromised immune system can result in opportunistic infections and certain cancers that a healthy immune response would typically combat effectively. Understanding this function is key in recognizing the destructiveness of HIV and the importance of treatment options available to manage and control the virus.
