In December 2019, the Wuhan health authorities detected
a few cases of an atypical pneumonia of unknown aetiology and
having symptoms like pyrexia, myalgia, fatigue, coughs, dyspnea,
and pneumonia (Shanker, 2020). By laboratory finding, this illness
was later confirmed as a novel coronavirus and initially named as a
2019 novel coronavirus (2019-nCoV). The disease name, as Corona
Virus Disease (COVID-19) was recommended subsequently by the
World Health Organization (WHO). The name SARS-CoV-2 instead
of 2019-nCoV was suggested by the International Committee on
Taxonomy of Viruses. WHO declared this recent ongoing viral out-
break as a pandemic on 11
th
March, 2020 and as an international
public health emergency on 30
th
January, 2020 [1].
The SARS-CoV-2 has a diameter of 50–200 nm, a spherical en-
velope, and a single-strand positive-sense RNA genome (30 kb in
length) [2]. The genome sequencing similarity of SARS-CoV-2 was
noticed as 79.6% and 96% with SARS-CoV and Bat-CoV, respec-
tively. The SARS-CoV-2 membrane having four major structural
proteins; namely, spike (S) glycoprotein, small envelope (E) glyco-
protein, membrane (M) glycoprotein, and nucleocapsid (N) pro-
tein [3].
SARS-CoV-2, a member of the Coronaviridae family and the
genus -coronavirus, shares genetic similarities with Bat-CoV
(RaTG13/Beta-CoV) [4]. According to Phylogenetic analyses and
by using the large sub genomic data set of bat coronaviruses, it’s
indicated that SARS-CoV-2 likely originated in horseshoe bats form
China, as its genome sequence has approximately 96% nucleotide
identity with RaTG13, isolated from Chinese Rhinolophus affinis.
The nucleotide similarity of Pangolin-CoV genome with SARS-
CoV-2 and Bat CoV RaTG13 was noticed as 91% and 90.6%, re-
spectively [5].
Although SARS-CoV-2 is alleged to have originated from an ani-
mal host (zoonotic origin) with further human to human transmis-
sion may has occur [6]. Sneezing and coughing are the most com-
mon symptoms of human coronavirus transmission by air from an
infected person to a healthy person. The virus transmission was
mainly noticed by the close physical contact like rubbing or shaking
of hands, close contact of the surface contaminated with the virus,
lips contact, nose or eyes contact before washing their hands [7].
Currently 625 outbreaks in animals have been reported glob-
ally, affecting 17 species in 32 countries including Dog, Cat, Tiger,
Lion, Puma, Ferret, Mink and Gorilla [8] and SARS-CoV-2 was ex-
perimentally inoculated by the intranasal route for the evaluation
of the susceptibility in several domestic animals. The results indi-
cate that Cat, Dog and Ferret are highly susceptible to SARS-CoV-2
[9]. The first case of COVID-19 was confirmed in a Malayan tiger
maintained at the Bronx Zoo, New York on 4th April 2020. The
zookeeper was suspected for COVID-19 infection spreading among
the captive wild felids. The SARS-CoV-2 isolated from the Malayan
tiger (SARS-CoV-2/tiger/NY/040420/2020) consists of a similar
whole-genome sequence with the available human sequences of
SARS-CoV-2 [10].
The clinical diagnosis of 2019-nCoV depends on the symptoms
and travel history to a country known to have the disease and/or
exposure to an infected person. The different testing procedures
for COVID-2019 have been published by WHO. The real-time re-
verse transcription polymerase chain reaction (RT-PCR) is the most
common technique used for the testing of COVID-2019. The RT-PCR
test may be done on respiratory samples like nasopharyngeal swab
or sputum samples [11].
