Aids is caused by HIV, which destroys important cells in the immune system. It was first described in 1979 and the virus was identified in 1983. Then, patients died because there was no treatment. Today there are many medicines. These allow people with AIDS to lead more normal lives. Extensive research is underway into even better medicines for the future.

Intro
FAQ: What can be done about it?
There has been a huge amount of effort devoted to the development of treatments for AIDS. In 1995 there were just three available drugs. Now there are twenty. They work by interfering with the normal life-cycle of HIV. This reduces the amount of virus in the body and considerably slows down the development of more serious symptoms.
Unfortunately, these medicines have complicated dosage schedules and can have unpleasant side effects. Also, HIV is a very changeable virus with new forms constantly emerging. This means that it becomes resistant to the drugs very quickly. It also means that it is difficult to design a protective vaccine that could prevent infections.
