Answer 3

• What is the most important thing to know in the diagnosis of an infectious disease?
• Physical appearance, and a physical provides evidence which allows for the doctor to see what physical problems are a major risk at the moment. The doctor can come across what systems or what physical problems are being effected by the disease, and can narrow down what disease is being the culprit.  

1. If you look at a patient and see that he has ashen skin, and labored breathe a doctor would automatically think that the patient just had a heart attack. 
2. If you take a physical you can see if there is anything abnormal about the body, and can pinpoint the system at risk by seeing what is wrong with the body.
3. A physical is also includes testings of different kinds, depending on the symptoms a certain test is administered. A high white blood count can shed evidence that there is an infection raging in the body.
