What Is HIV?
HIV stands for human immunodeficiency virus. This virus causes the body’s immune system to break down. Your immune system fights off illness and infection and is important for a healthy body.
HIV attacks important white blood cells in your immune system called lymphocytes, or T-cells. T-cells identify and destroy invading organisms in the body. Once attached to the T-cell, HIV multiplies and destroys the cell. When your body loses enough T-cells, it can become very sick. It gets infections that a healthy person’s immune system would normally fight off. This includes infections such as colds, flu and other viruses.
