The COVID-19 pandemic is raging across the globe, with the total active cases increasing each day. Globally over 63 million COVID-19cases and more than 1.4 million deaths have been reported to WHO. Throughout the world, academicians, clinicians and scientists are working tirelessly on developing a treatment to combat this pandemic. The origin of novel SARS-CoV-2 virus still remains foggy but is believed to have originated from a bat coronavirus RaTG13 with which it shares approximately 96% sequence similarity. In the present review, the authors have provided an overview of the COVID-19 pandemic, epidemiology, transmission, developments related to diagnosis, drugs and vaccines, along with the genetic diversity and lifecycle of the SARS-CoV-2 based on the current studies and information available.

Keywords: COVID-19, SARS-CoV-2, ACE2, spike, diagnosis, vaccine.
