HIV or Human Immunodeficiency Virus is a disease transmitted by five bodily fluids (blood, semen, vaginal fluid, breastmilk, and pre-seminal fluid) which weakens the human immune system. The immune system is the body’s defense against illnesses. HIV reprograms cells that protect the immune system and uses them to reproduce. With treatment, infection can be controlled. If untreated, the infection can cause serious or life-threatening vulnerabilities to other diseases.
