There are all sorts of ways to get an infectious disease. They can pass from person to person. Insect or animal bites can transmit disease. Infectious diseases are also acquired by eating contaminated food or drinking dirty water, or being exposed to harmful organisms in the environment. These diseases can be caused by bacteria, viruses, parasites and other micro-organisms.
