AIDS -- Something none of
us wants to catch. Even though this is a deadly disease, it is not as
contagious as other infectious diseases.
Infectious diseases are spread by
germs. These are different from diseases you might inherit from your
parents. The
reasoning for that is that is AIDS (caused by the HIV virus) is only spread by blood, or body fluids.
Other diseases can be spread as the germs can be airborne. These are two
ways to prevent yourself from getting AIDS.
