Coronavirus-19 is a severe acute respiratory disorder in humans which has become a major
health problem. It spreads out very rapidly throughout the world since it has been first identified in
Wuhan, China (December 2019). The causative virus is known as severe acute respiratory syndrome
coronavirus 2. And the World Health Organization has named this respiratory syndrome as a new epidemic
disease called COVID-19. The incidence of COVID-19 continued to increase with three million
confirmed infected cases and with 244,000 death cases worldwide. Until now there is no specific
treatment or vaccine available against COVID- 19. The collective information about the different aspects
of COVID-19 viral infection has been gathered from renowned journals, and electronic databases
including Science Direct, Web of Science, Scopus and PubMed from 1990 to 2020. This manuscript
has highlighted the transmission and symptoms of Covid-19. Therefore, these studies show how the
SARS-CoV 2 can facilitate the debut of the virus into targeted host cells.
