What is AIDS?

AIDS is the abbreviation of "Acquired Immune-Deficiency Syndrome", and it is a serious contagious disease caused by the "Human Immunodeficiency Virus" (HIV). Until now, HIV has been found to have two types: HIV-1 type and HIV-2 type.

The virus can destroy human immunity, making an AIDS patient weaker and unable to resist any infection or the invasion of cancer. In the initial stages, the patient would suffer from symptoms similar to a cough or serum disease, followed by a long symptomless infection phase. Then following, is an AIDS pro-phase and an AIDS phase. AIDS is not a single disease, but rather multiple infections invading the body at the same time. Drug therapy may lengthen the patient’s survival time, but if the patient is not treated, many kinds of severe opportunistic infections and malignant tumors can occur.
