“…Effectiveness of consistent promotion and application of basic and advanced infection control procedures in reduction of cases has been demonstrated in hospital-associated MERS-CoV outbreaks in Saudi Arabia and Korea [53,85,91]. However, MERS-CoV has a high morbidity and case-fatality rate, particularly among ICU and/or critically ill patients, those with comorbid illness, older patients and those with a high viral load [11,12,15,[92][93][94]. The potential for viral mutations, for example in the viral spike (S) protein, which mediates viral entry into host cells, or in viral proteases such as Mpro, could increase viral affinity for human host cells and expand host cell range [50,[94][95][96].…”
