i can identify the meaning of disease, bacteria, virus, germ, and pathogen.

i learned that there are 2 types of diseases. communicable, and noncommunicable.
communicable diseases are contagious and noncommunicable diseases are not.
AIDS is an example of a communicable disease because it can be spread. i learned that
people who have AIDS don't die from the infection itself, they die because it destroys their immune system so they can't fight off other diseases.
