Answer:
Acquired immunodeficiency Syndrome (AIDS) is a syndrome caused by the human immunodeficiency virus (HIV). Up till today, there is not a proper cure for the syndrome but specific drugs can be given to the patient to control or reduce the virus in the patient. Some of the medicines used are:
Lamivudine (Epivir, 3TC), Tenofovir (Viread, TDF), Abacavir (Ziagen, ABC), Indinavir (Crixivan, IDV) etc.
The treatment of AIDS is nowadays far better than the initial years in which AIDS became common. Scientists could not make medicines for reducing the HIV virus and also did not know how this virus spread from one person to another.
In the near future, scientists are working hard to produce vaccines for developing immunity against the virus and also looking for genetic engineering methods to treat AIDS.
