Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging immune system, HIV interferes with body's ability to fight the organisms that cause disease. HIV is a sexually transmitted infection. It can also be spread by contact with infected blood or from mother to child during pregnancy, childbirth or breast-feeding. Without medication, it may take years before HIV weakens your immune system to the point that you have AIDS.
Disease Symptoms and Treatment
Each class of anti-HIV drugs blocks the virus in different ways. It's best to combine at least three drugs from two classes to avoid creating strains of HIV that are immune to single drugs. The classes of anti-HIV drugs include: Non-nucleoside reverse transcriptase inhibitors. Examples include efavirenz (Sustiva), etravirine (Intelence) and nevirapine (Viramune) etc.
According to World health rankings the Death Rate (Age Standardized) of HIV/AIDS patients was found to be 0.60 % Per 100,000 people during the year 2014.
