Patient case (clinical description): The patient is a 38-year-old man with cough and body ache that started 3 days ago.  He had fever and chills at the beginning and has low grade fever at the time of visit. He feels tired and sleepy. His body ache and myalgia get better after using Tylenol. The PCR test for Covid is positive. His vital signs are within normal limits with a body temperature of 37.9 C. There is no lymphadenopathy or white exudates in the pharynx.

Patient's own account: I was feeling really sick the other day, to the point that I showed up at the doctor's office. I was coughing, and my body was hurting for 3 days. I had a fever and chills and felt tired and sleepy. I got better after using Tylenol. They did a PCR Covid test on me, and it was positive! My vitals were normal, and my temperature was 37.9 C. I had no swelling around my neck or white spots on the back of my throat.

                  infarction, unchanged stable conduction abnormalities e.g. right bundle branch
                  block, or any other finding which does not significantly impact mortality would
                  be considered non-clinically significant findings and subjects with these
