📖 Introduction
What is HIV? An Overview
HIV stands for Human Immunodeficiency Virus. It is a specific type of virus that targets and significantly damages the immune system within the human body. This attack compromises the body's natural defenses.
Definition: HIV is a retrovirus that primarily infects components of the human immune system, such as CD4+ T cells, macrophages, and dendritic cells.
Targeting Key Immune Cells
The virus primarily targets and damages CD4 immune cells. These are a crucial type of White Blood Cell, playing an essential role in orchestrating the body's immune response against infections and various diseases.
By destroying these vital cells, HIV progressively weakens the immune system. This makes the infected individual increasingly susceptible to illnesses that a healthy immune system would normally fight off.
Impact on the Body's Defenses
Over an extended period, the continuous assault by HIV severely debilitates the body's immune system. This leaves the individual highly vulnerable to a range of opportunistic infections and certain types of cancers.
Key Concept: HIV does not directly cause death, but rather creates a state of severe immunodeficiency (AIDS) that allows other infections and cancers to thrive, ultimately leading to severe health complications.
