aids is a disease that breaks down the body's immune system and leaves a person defenceless against infections and illnesses. people get aids after having been infected with hiv, the virus that causes the disease. there are millions of people who die of aids every year.
so far, there is no treatment available for the disease and aids patients have to deal with the fact that they might die young. unfortunately, a deadly disease such as aids also frightens others. because of a lack of knowledge about how it gets transmitted, people often treat aids patients as if they were bad or dangerous.
