1.) Symptoms may relate to another medical condition or an underlying harmless effect of another disease, but symptoms are a main factor in diagnosing an infectious disease, symptoms help you identify what is being effected, which helps narrow down the possible diseases.
2.) My three evidence are Epidemiological Triad, Similar Diseases, and Bacterial vs. Viral Infection.
Epidemiological Triad- When a new disease emerges, epidemiologists use the Triad, including symptoms, so they see what if the unknown disease affecting.
Similar Diseases- When you know the symptoms you can relate them to other diseases that maybe similar to what is effecting the host. When Ebola first came out, the epidemiologists related it to the Dengue Fever, a disease that is very similar to Ebola.
Bacterial vs. Viral- The symptoms usually tell if someone has a bacterial or viral infection. One common symptom attached to bacterial diseases, is a fever. Another thing that helps pinpoint a bacterial infection is that they are usually a respiratory, or digestive tract infection.
3.) I haven't really put my sources on my WB, because the second two were common knowledge, and the first one, I just read up on a website and didn't think about using it as an article. But I found four sources that prove my answers.
