Abstract: Coronavirus disease 2019 (COVID-19) is a severe acute respiratory syndrome caused by a novel strain of coronavirus (SARS-CoV-2) which was declared by WHO as a cause of global pandemic. By human-to-human transmission it caused severe damage to mankind with increased mortality rate worldwide. Coronavirus is a spherical enveloped virus with single stranded positive-sense RNA with a size of ~30 kilobases encoding various structural, non-structural and accessory proteins. The entry of coronavirus into the host cells is mediated by spike proteins. SARS-CoV-2 efficiently replicates in host cell and by evading immune surveillance, like innate and adaptive immune responses, in the host cells ultimately leads to increased virulence and disease outcome. In the current review, we highlighted the molecular insights of SARS-CoV-2 and its infection mechanism in the host cell via host-viral protein interactions based on currently available data up to 16thMay 2020 using various research literature databases. The diagnostics of SARS-CoV-2 is mainly done by RT-qPCR and serological tests. There is no effective treatment for COVID-19, however, few methods like plasma therapy and remdesivir treatment are reported to show promising results in improving patient's health and decreasing mortality rate.
