Coronavirus outbreak has challenged the medical, public health infrastructure and economic status of nearly all countries across the World. The main issue of concern with SARS-CoV-2 has been the high infectivity rate and the high mortality rate especially, observed during the wave 2 of COVID-19. The symptoms associated with SARS-CoV-2 are often misleading with influenza and another respiratory tract seasonal viral infection as, majority of the patients report common constitutional symptoms. Hence, correct diagnosis for COVID-19 may play a key role in early detection, management and curtailment in the transmission rate.Therefore, apart from limiting this outbreak, efforts need to be made to plan comprehensive and stringent measures to develop diagnostic tools to prevent future outbreaks of this zoonotic disease. The present manuscript provides a detailed description of various indices and parameters which are currently being used for easier, rapid, accurate diagnosis, medical managementand prognosis assessment of COVID-19 patients in various stages of the disease.
