Human immunodeficiency syndrome (HIV): It is a virus that suppresses the immune system and causes acquired immunodeficiency syndrome (AIDS) over time. The suppression of immunity leads to the development of opportunistic infections. It is a life-long condition and there is no permanent cure. The treatment (antiretroviral therapy) is given to suppress the infection. If the right treatment is not provided, then it may affect and kill immune cells which can put the body at high risk of getting serious infections. HIV can transfer from one person to another by blood, vaginal and rectal fluids, breast milk and semen.
