How is AIDS treated?
Several drugs are now available to treat HIV infection. Some, including AZT, interfere with the virus as it tries to copy itself inside the immune system cells. Other drugs stop the virus maturing and leaving the cells. None of these drugs cures HIV infection or AIDS, although when used in combination they can delay the appearance of symptoms, perhaps indefinitely. However, not everyone in the world infected with HIV can afford, or get access to, these drugs.
