Human Immunodeficiency Virus (HIV)

HIV or Human Immunodeficiency Virus is a lentivirus, which is a sub-classification of the retrovirus. It causes the HIV infection which over time leads to AIDS or Acquired Immunodeficiency Syndrome. AIDS is a deadly condition in which the affected person’s immune system fails leading to the spread of life-threatening infections and cancers in his body. The average survival period for a person affected with HIV without treatment is nine to eleven years subject to the subtype of HIV. HIV infection can occur by the transference of blood, breast milk, vaginal fluid, semen or pre-ejaculate. HIV occurs as both free virus particles and as virus inside the infected immune cells within the above-mentioned bodily fluids.
