COVID-19 is certainly the greatest global health problem now and for the foreseeable future. Clinicians and scientists from all over the world have been producing evidence to understand the epidemiology, clinical profile and prognostic factors of COVID-19. In the last six months a large list of COVID-19 symptoms including loss of taste and smell have emerged which can be used for screening and risk stratification. Robust workup of this evidence will help to reach strong conclusions to advance clinical medicine, epidemiology, public health, immunology and evidence-based treatment options in the spectrum of disease that we now know as COVID-19.
