What is HIV?

HIV is the Human Immunodeficiency Virus. It attacks your body's immune system by destroying CD4 cells, which help your body fight diseases. HIV can severely damage your immune system and lead to AIDS.

How is HIV treated?

HIV treatment may reduce the amount of HIV in your blood (called "viral load"). Treatment may also help to increase the number of CD4 cells in your blood which help fight off other infections.
