Epidemic and Pandemic Worksheets

There is a wide array of aliments that can affect the human body. Some diseases can be caused by our genetics, toxins, or the environment that we are surrounded by. Heart disease is an example of these types of non-infectious diseases. If someone contracts heart disease, they cannot transmit that disease to people. There are also diseases that are cause ridiculously small organisms we commonly refer to as germs. The scientific word for germs is pathogens. This types of organisms can cause an infectious disease, which we can transmit to other people. There five types of pathogens bacteria, fungi, protozoa, viruses, and worms. Although who knows what Mother Nature will throw at us in the future? Pathogens make their way into our bodies through all the openings on our bodies. That includes our mouths, noses, eyes, and any cut that is exposed. Pathogens can enter and not cause disease, but if they are able to make their way an begin to make a lot of copies of themselves, that is when the trouble begins. Our immune system immediately begins to work against the pathogen with the help of our white blood cells and antibodies. This heightened immune response causes many of the symptoms that we see as a result of infection. Our body heats up, causing a fever to help fight off the infection. This series of reading worksheets will explore various rates of infectious disease outbreaks.
