Giantmicrobes HIV - Small
H.I.V. (human immunodeficiency virus) is a virus that kills the CD4 cells, or T-helper cells, which help the body fight infections. Once the body's immune system has been compromised, a person develops AIDS (acquired immunodeficiency syndrome). H.I.V. is found in bodily fluids, and it can be transmitted when these come into contact with an uninfected person's broken skin or mucous membranes. The most common means of transmission by far are: Sexual contact with an infected person, Sharing needles or syringes (primarily for drug injection) with someone who is infected, During pregnancy or birth to babies of HIV-infected mothers, or through breast-feeding after birth. Giantmicrobes are based on actual microbes, cells, organisms and other critters, only 1,000,000 times actual size!
