Abstract

Abstract : Aim: To compare the clinical features of Middle East respiratory syndrome coronavirus (MERS‐CoV) infection between paediatric and adult cases. Methods: Using multiple public data sources, we created an enhanced open‐source surveillance dataset of all MERS‐CoV cases between 20 September 2012 and 31 December 2018 in Saudi Arabia including available risk factor data. Results: Of the 1791 cases of MERS‐CoV identified, 30 cases (1.7%) were aged under 18 years and 1725 cases (96.3%) were aged 18 years and over. Three paediatric cases were fatal, aged 0, 2 and 15 years. The odds of asymptomatic MERS‐CoV infection among cases under 18 years ( n = 10/23; 44%) was significantly higher (odds ratio (OR) = 4.98; 95% confidence interval (CI): 2.15–11.51; P = 0.001) compared to adults ( n = 199/1487; 13%). The odds of hospitalisation were significantly lower (OR = 0.17; 95% CI: 0.08–0.39; P < 0.001) among cases under 18 years ( n = 12/24; 50%) compared to adults ( n = 1231/1443; 85%). Children were more likely to have a known source of exposure compared to adults (OR = 2.68; 95% CI: 1.29–5.56; P = 0.008). Conclusions: Clinically severe illness is less common in children, although death can occur, and the proportion of paediatric cases (1.7%) is similar to that reported for COVID‐19. Age‐specific differences in the clinical presentation of MERS‐CoV cases could have implications for transmission for other betacoronaviruses including severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Children may be at risk within the household with an infected adult. More studies are required on the role of children in transmission of betacoronaviruses.
