Introduction
Middle East Respiratory Syndrome coronavirus (MERS-CoV) is the
causative factor for this disease.
It can spread from the animals to human and this virus family is
associated with the respiratory infections
MERS-CoV was first detected in Saudi Arabia in 2012.
After detection of the virus in Saudi Arabia in 2012, it spreaded to
the other countries of middle east Asia and also affect the people
globally.

Determinants of the Disease
MERS-CoV can be transmitted through a
number of ways.
Primary source of MERS-CoV transmission
Person to person transmission
Household transmission
Nosocomial transmission
Transmission by asymptomatic individuals
Document Page

The primary source of the MERS-CoV
infection is the human infection acquired
in human the community . However, the
exact source an mode of transmission is
still known accurately.
However, bat is identified as one of the
primary source of infection.
Camel is detected as another causative
animal for the transmission of this
disease (Zhang, Shen & Gu, 2016).
People who are in close contact with the
dromedary camels are more vulnerable to
be affected by the MERS-CoV infection

Person to Person Transmission
Person to person transmission can be
happened through urine, nasal swabs,
feces, bloods, lung tissues.
Sometimes, MERS-CoV can be detected
in the serum of the blood. People who
are giving care to the infected people
can also get the infection from those
patients.
However, MERS-CoV only can be
transferred from one person to another
only when there is direct contact with
the infected patients.
Document Page
Nosocomial Transmission
Nosocomial transmission is one of the leading cause of MERS-CoV transmission
and every 1 out of 3 cases is due to nosocomial transmission in the world.
MERS-CoV is more stable in cold and dry weather.
Lack of maintaining proper control measure can cause nosocomial
transmission.

Indicators of the Disease
The determinants of the MERS-
CoV are as follows-
Gastrointestinal symptoms
respiratory problems
Organ Failures
Chronic disease
Problems in the immune
system

Measurement of the Disease
The prevalence of the disease in Saudi
Arabia is a serious matter of concern
Not only this, the MERS-CoV infection is
not quite uncommon in other countries of
the world (Aghazadeh-Attari et al., 2018).
The prevalence rates are different for the
various causative factors.
The MERS-CoV infection is also
associated with the mortality and
morbidity of the patients in Saudi Arabia.
Serological analysis showed that 44
cases out of 280 cases were found to be
affected by the infection.
Almost 34 out break cases were reported
in the hospital of Riyadh in 2017 (Hui et
al., 2018)

Prevalence of cases of MERS-CoV
Document Page
Continued..
In the hospital setting, the prevalence
rate of the infection was different from
one unit to another.
Contaminated environments can also
cause infection in the health care
setting.
As a primary source of infection, camel
can cause infection MERS-CoV infection
(Hui et al., 2018)
