Things about AIDS:
Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a disease you can get, and once you have it, you have it for life. Once your number of T Cells (the disease fighting cells) gets below a certain number, you no longer have HIV, you have AIDS.
AIDS can be spread by any of your bodily fluids touching infected fluids of another person. Animals can not get HIV/AIDS.
