Abstract:
The end of 2019 marked the start of coronavirus disease
(COVID-19) pandemic from China, which went on to
envelope more than 190 countries and territories across
the globe. Severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2), from a group of betacoronaviruses, is
responsible for COVID-19. The virulent factors include the
presence of envelope and spike proteins having receptor
bonding domains (RBD). Clinical manifestations can range
from mild respiratory infections to fatal outcomes. The
viability of virus ranges from 3 to 72 hours. Polymerase
chain reaction (PCR) is the diagnostic test of choice in this
pandemic situation. Due to the absence of specific
antivirals and vaccine, adoption of preventive option can
help to combat the specific life-threatening outcomes.
