Coronavirus Anatomy and Its Analytical Approaches for Targeting COVID-19.

The whole world has lived in fear of the Coronavirus 2019 (COVID-19) for more than one-fourth of a year in 2020. Since then, numerous studies have been done and others are still being conducted to identify the coronavirus causal agent and determine the ideal antiviral therapies for treating this illness. Despite the fact of significant global efforts, which are being made to develop vaccines and identify therapeutic medicines, the emergence of multiple variants has rumbled the research for developing an ideal diagnostic and therapeutic tool for targeting COVID-19. A thorough anatomy of the coronavirus virus and its global dissemination is essential for healthcare initiatives, as well as for predicting and preventing new epidemics. Testing for active COVID-19 infections is a critical public health strategy for tracking the epidemic. The widespread adoption of polymerase chain reaction (PCR) and antigen rapid test assays has increased the supply of test kits. In this chapter, the significance of molecular technique to develop prognostic analytical techniques for targeting COVID-19 along with the advantages and limitations of available techniques is discussed.
