 The human immunodeficiency infections are 2 types of Lentivirus that contaminate people. After some time, they cause Acquired Immunodeficiency Syndrome (AIDS), a condition wherein dynamic disappointment of the resistant framework permits perilous deft diseases and malignant growths to blast. Without treatment, normal endurance time after contamination with HIV is evaluated to be 9 to 11 years, contingent on the HIV subtype. By and large, HIV is an explicitly transmitted disease and happens by contact with or move of blood, semen, pre-discharge, and vaginal liquids. Exploration has appeared (for both same-sex and other gender couples) that HIV is untransmittable through condomless sex if the HIV-positive accomplice has a reliably untraceable viral burden. Non-sexual transmission can occur from a contaminated mother to her baby during pregnancy, through labor by presentation to her blood or vaginal liquid, and through bosom milk. Inside these natural liquids, HIV is existent as both free infection particles and infection in tainted resistant cells. HIV is a long lasting condition and presently there is no fix, albeit numerous researchers are attempting to discover one. Be that as it may, with clinical consideration, including treatment called antiretroviral treatment, it's conceivable to oversee HIV and live with the infection for a long time.
