Abstract
Since the beginning of Corona Virus Disease (COVID) pandemic, there has been lack of clarity about the management protocols in spite of frequently updated national and international guidelines. Irrational use of unproven therapies has not been helpful in improving treatment outcomes. Early use of high-dose steroids or late use of antiviral medicines might have caused more harm than the benefit. There is also lot of fear about post-COVID fibrosis leading to extended use of steroids and antifibrotics. We reviewed the available COVID guidelines and treatment protocols in the light of scientific evidence generated over last 2 years by a systematic literature search using various databases (PubMed, Google Scholar, MEDLINE, UpToDate, Embase, and Web of Science). This article presents a comprehensive approach to the diagnosis, appropriate investigations, their interpretations, and use of specific therapies according to the stage of disease.
