ABSTRACT
Middle East respiratory syndrome (MERS) is a viral respiratory
disease caused by a novel coronavirus (Middle East respiratory
syndrome coronavirus, or MERS‐CoV) that was first identified in
Saudi Arabia in 2012. Coronaviruses are a large family of viruses that
can cause diseases ranging from the common cold to Severe Acute
Respiratory Syndrome (SARS). SARS coronavirus (SARS-CoV) –
virus identified in 2003. Typical MERS symptoms include fever,
cough and shortness of breath. Pneumonia is common, but not always
present. Gastrointestinal symptoms, including diarrhoea, have also
been reported, whereas the Symptoms of SARS include fever, malaise,
myalgia, headache, diarrhoea, and shivering (rigors). No individual
symptom or cluster of symptoms has proved to be specific for a
diagnosis of SARS. MERS-CoV is a member of the family
Coronaviridae, As of January 20, 2017, the WHO had received reports from 27 countries of
1879 cases of laboratory confirmed MERS and at least 659 related deaths. As of Jan 23,
2020, confirmed cases were consecutively reported in 32 provinces, municipalities, and
special administrative regions in China, including Hong Kong, Macau, and Taiwan.
Seroepidemiologic studies have shown that antibodies to MERS-CoV are present in
dromedary camels (Camelus dromedarius). The majority of severe MERS cases have
occurred in adults older than 50 years of age who have coexisting conditions such as diabetes,
hypertension, cardiac disease, obesity, chronic respiratory disease, end-stage renal disease, or
cancer or in persons receiving immunosuppressive therapy. No vaccine or specific treatment is currently available, however several MERS-CoV specific vaccines and treatments are in development. Treatment is supportive and based on the patient’s clinical condition.
