A Mild Case of COVID-19 Infection: An Observational Longitudinal Study 27 Days Post Symptom of Antigen, Antibodies (IgM & IgG), IL-6 and D-Dimer |Biomedgrid

A 58-year-old male developed symptoms of COVID-19 infection, fever, aches and pains and general malaise. The next day the symptoms got worse and his breathing became laboured on climbing the stairs. He had a throat and nose swab which tested positive using a COVID-19 antigen test and the diagnosis was confirmed using PCR test. Swabs and blood samples were taken daily till day 27 post onset of symptoms and analysed for COVID-19 antigen, Covid19 antibodies, IL-6, D-dimer, CK-MB, Troponin and Myoglobin. His nasopharyngeal swabs remained positive for 15 days post onset of symptoms, his IgM and IgG seroconversion started on day 10 and 11 post onset of symptoms, respectively. His interleukin-6 levels were elevated on day 1 and was elevated most of the time until day 8 when it returned to normal. His D-dimer concentrations were elevated from day 1 and remained elevated fluctuating up and down till day 24 post onset of symptoms.
