"SARS-CoV2", a previously unknown strain of coronaviruses caused a severe
respiratory disease called Coronavirus disease (COVID-19) which emerged from
Wuhan city of China on 30 December 2019, and declared as Global health problem by
World Health Organisation within a month. In less than two and half months (11
March, 2020) it was declared as a pandemic disease due to its rapid spreading
ability, it covered more than 211 countries infecting around 1.7 million persons
and claiming around 1.1 lakhs lives within merely 100 days of its emergence.
Containment of the infection of this virus is the only available measure to
control the disease as no vaccine or specific antiviral treatment is available.
Confirmed detection of the virus followed by isolation of the infected person at
the earliest possible is the only measure to prevent this disease. Although there
are number of methods available for detection of virus and to combat this disease
in the present pandemic situation, but these available diagnostic methods have
their own limitations. The speedy and exponential global spread of this disease
strongly urges the fast and economic diagnostics tools. Additional to the
available diagnostic methods, there is a sudden surge for development of various
of methods and platforms to diagnose the COVID-19. The review summarized the
advantage and disadvantage of various diagnostic approaches being used presently
for COVID-19, newer detection methods in developmental stage and the feasibility
of advanced platforms like newer nano-sensor based on-the-spot detection
technologies.
