The respiratory sickness Middle East respiratory syndrome (MERS) caused by a
coronavirus (Middle East respiratory syndrome coronavirus or MERS-CoV) was
first recognized in Saudi Arabia in 2012.
Coronaviruses (CoVs) belong to the order Nidovirales, possess the most complex and the largest RNA genomes ever described to date that allow them to speedily adapt to new hosts. The first human CoV was recognized in the mid-1960s.
About 35% of the patients reported with MERS-CoV infection have passed away.
CoV spreads from person-to-person through aerosolized droplets originated from
coughs and sneezes of infected people through air and contaminated material.
Even though most of the human cases of MERS-CoV have been recognized to
human-to-human infections scientific facts propose that dromedary camels are a
key reservoir host for MERS-CoV (Hemida et  al. 2017). As per Philippe (2020)
evidence suggests that MERS and SARS viruses originated from bats and they are
assumed to have undergone wide recombination with CoV from other animals
ahead of infecting humans.
Health care-related outbreaks have occurred in a number of nations, with major
outbreaks seen in United Arab Emirates, the Republic of Korea, and Saudi Arabia.
The most overwhelming examples of CoV epidemics were the SARS and the MERS
outbreaks in 2002 and 2012, respectively, followed by a novel corona virus outbreak
in 2019.
Since 2012, 27 nations reported cases of MERS with 2494 laboratory-confirmed
cases of MERS were reported globally at the end of November 2019 that include
858 associate deaths, majority of which were reported from Saudi Arabia
(WHO 2019b).
In the late December, 2019, the outbreak of respiratory syndrome, started in
Wuhan, China (Nanshan et al. 2020) have spread to 28 other countries and territories by first week of February 2020 (CDC 2020).
The transmission of disease occurred in four stages across the globe after it originated in China. Stage 1 is the stage of being the disease imported, stage 2 being
local transmission, stage 3 being community transmission, and stage 4 being the
disease turning into an epidemic.
Many patients in Wuhan were epidemiologically associated with the Huanan
seafood market in Wuhan, where numerous non-aquatic animals were also sold
before the outbreak (Roujian et  al. 2020). On January 23, Wuhan authority shut
down all public transport in the city. Quarantine orders were extended to other 15
cities in China locking down 50 million people in China. The corona virus killed
more than 630 and affected about 31,000 in Wuhan, China by the second week of
February 2020 (Business insider 2020).
The lockdown of Wuhan that was extended to other places of Hubei province
prevented business-related travel and transportation of goods. Restaurants, transport
