摘要:
There is a new public health crisis threatening the world with the emergence
and spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The
disease was later named novel coronavirus disease or COVID-19. It was then declared a
pandemic by the World Health Organization on March 11, 2020. The virus originated in
bats and was transmitted to humans through unknown intermediary animals in Wuhan,
Hubei province, China, in December 2019.
As of February 5, 2021, 103 million laboratory-confirmed cases and nearly 2.3 million
deaths were reported globally. The number of death tolls continues to rise, and a large
number of countries have been forced to maintain social distance in public place and enforce
lockdown. As per literature, coronavirus is transmitted human to human or human
to animal via airborne droplets. Coronavirus enters the human cell through the membrane
ACE-2 exopeptidase receptor. WHO, ECDC, and ICMR advised avoiding public places
and close contact with infected persons and pet animals. To date, there is no evidence of
any effective treatment for COVID-19. The main therapies being used to treat the disease
are antiviral drugs, chloroquine/hydroxychloroquine, and respiratory therapy. Although
several therapies have been proposed, quarantine is the only intervention that appears to
be effective in decreasing the contagion rate. We conducted a literature review of publicly
available information to summarize knowledge about the pathogen and the current epidemic.
In the present literature review, the causative agent of the pandemic, epidemiology,
pathogenesis, and diagnostic techniques are discussed. Further, currently used treatment,
preventive strategies along with vaccine trials and computational tools are all described
in detail.
