HIV
HIV stands for: Human Immunodeficiency Virus
HIV is a virus. Viruses such as HIV cannot grow or reproduce on their own, they need to infect the cells of a living organism in order to replicate (make new copies of themselves). The human immune system usually finds and kills viruses fairly quickly, but HIV attacks the immune system itself – the very thing that would normally get rid of a virus.
With around 2.6 million people becoming infected with HIV in 2009, there are now an estimated 33.3 million people around the world who are living with HIV, including millions who have developed AIDS.
It takes around ten years on average for someone with HIV to develop AIDS. However, this average is based on the person with HIV having a reasonable diet, and someone who is malnourished may well progress from HIV to AIDS more rapidly.

What is the connection between HIV and AIDS?
HIV causes AIDS by damaging the immune system cells until the immune system can no longer fight off other infections that it would usually be able to prevent.It takes around ten years on average for someone with HIV to develop AIDS. However, this average is based on the person with HIV having a reasonable diet, and someone who is malnourished may well progress from HIV to AIDS more rapidly.
