Middle Eastern Respiratory Syndrome Corona Virus (MERS CoV): case reports from a tertiary care hospital in Saudi Arabia

BACKGROUND AND OBJECTIVES: Middle Eastern respiratory syndrome caused by novel coronavirus (MERS CoV) has been a major public health challenge since it was first described in 2012 in Saudi Arabia. So far, there is no effective treatment for this serious illness, which features a high mortality rate. We report an initial experience of the use of ribavirin and interferon (IFN)-α2b in the management of MERS CoV at a tertiary care hospital. DESIGN AND SETTINGS: A case series of 6 patients admitted with a confirmed diagnosis of MERS CoV were treated with ribavirin and IFN-α2b in addition to supportive management. The patients' demographics, clinical parameters, and outcomes were recorded. Fifty-four close contacts of these patients were screened for MERS CoV. METHODS: Six patients with MERS CoV infection were included in this study. Four cases featured symptomatic disease, including pneumonia and respiratory failure, while 2 were asymptomatic close contacts of the MERS CoV patients. The MERS CoV infection was confirmed by reverse transcription–polymerase chain reaction detection of the consensus viral RNA targets upstream of the E gene (UPE) and open reading frame (ORF1b) on a sputum sample. The patients' demographics, comorbid conditions, time to diagnosis and initiation of treatment, and clinical outcomes were recorded. RESULTS: Three out of 6 patients who had comorbid conditions died during the study period, while 3 had successful outcomes. The diagnosis and treatment was delayed by an average of 15 days in those patients who died. Only 2 close contacts out of the 54 screened (3.7%) were positive for MERS CoV. CONCLUSION: Treatment with ribavirin and IFN-α2b may be effective in patients infected with MERS CoV. There appears to be a low infectivity rate among close contacts of MERS CoV patients.
