Start by learning about their biology
– what type of cell are they and what types of structures do they have?
Move on to the disease they cause
– what is the name of the disease, who do they infect, how do they
infect, what symptoms they cause, and how we treat them?
Finish up with why should we care about them
– are infections on the rise due to something that has changed, is the infection hard to treat with what we have available (antibiotics, vaccines, antiviral drugs), has the microbe mutated to become more dangerous?
