Instructions: Doctors must be able to accurately identify a disease in order to effectively treat it. On the back of this paper, create a flow chart that uses symptoms to separate out all of the bacterial and viral diseases listed below. A good flow chart will use clear, unambiguous distinctions and should have the fewest steps possible. See the example below.

Bacterial Diseases	Mode of Transmission	Symptoms
Tuberculosis	Airborne water droplets	Fatigue, persistent cough, bleeding in lungs; can be fatal
Diphtheria	Airborne water droplets	Fever, sore throat, fatigue
Scarlet Fever	Airborne water droplets	Rash, fever, sore throat
Bubonic plague	Fleas	Swollen glands, bleeding under skin; often fatal
