The risk factors associated with MERS-CoV patient fatality: A global survey

Risk factors associated with Middle East respiratory syndrome coronavirus (MERS-CoV)
infection outcome were established by analyses of WHO data from September 23, 2012 to 18
June 2018. Of the 2220 reported cases, 1408 cases, including 451 MERS-CoV deaths, were
analyzed. The case fatality rate was 32% (95% CI: 29.4–34.5). Compared to MERS patients ≤ 30
years old, those with >30 years had the adjusted odds ratio estimate for death of 2.38 [95% CI:
1.75-3.22]. This index was 1.43 [95% CI: 1.06-1.92] for Saudi patients in comparison to non-
Saudi; 1.76 [95% CI: 1.39-2.22] for patient with comorbidity in comparison to those without
comorbidity; 0.58 [95% CI: 0.44-0.75] for those who had close contact to a camel in the past 14
days and 0.42 [95% CI: 0.31-0.57] for patients with >14 days with onset of signs and hospital
admission compared to patients with ≤14 days.
