It belongs to the genus Lentivirus and the family called a retrovirus. HIV possesses a difference in structure from the retroviruses and is spherical and has a diameter of 120 nanometers (nm) that is 60 times smaller when compared to the red blood cells. Infection occurs via the transferring of vaginal, semen, breast milk or pre-ejaculation fluid.
