AIDS

A group of ailments brought on by infection with the retrovirus known as the human immunodeficiency virus (HIV), including the human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS). After the first infection, a person could not exhibit any symptoms or might go through a brief period of influenza-like sickness. Usually, a protracted incubation period without symptoms comes afterwards. The danger of getting common illnesses like TB, other opportunistic infections, and tumors—all of which are uncommon in persons with healthy immune systems—increases as the infection worsens because it interferes more with the immune system. The term "acquired immunodeficiency syndrome" refers to these post-infection symptoms (AIDS). Unintentional weight loss is frequently correlated with this period as well. HIV is typically passed from mother to child through pregnancy, childbirth, or nursing, unprotected intercourse (including anal and vaginal sex), tainted blood transfusions, and hypodermic needles. Saliva, sweat, and tears are a few physiological fluids that don't spread the infection. There is minimal to no danger of viral transmission during oral sex. Safe sex, needle exchange programmes, treating sick people, and pre- and post-exposure prophylaxis are all examples of preventative strategies. Antiretroviral therapy for both mother and child can frequently avoid disease in a newborn.
