Abstract
Middle East Respiratory Syndrome coronavirus (MERS-CoV) was initially isolated from a patient who was admitted to a private hospital in the Western part of the Kingdom of Saudi Arabia in 2012. Subsequently, MERS-CoV resulted in many sporadic cases, multiple intrafamilial transmission, and major outbreaks in healthcare settings. Of all the cases reported within the Kingdom of Saudi Arabia, 38% of the cases were primary, 45% were healthcare-associated infection, and 14% were household infections. The clinical spectrum of the MERS-CoV infection ranges from asymptomatic infections, mild or moderately symptomatic cases, and severe disease requiring intensive care unit admissions and may result in death. Within healthcare settings, transmissions of MERS-CoV are facilitated by overcrowding, poor infection control measures, unrecognized infections, and superspreader phenomenon. Currently, there is no approved therapy for MERS-CoV and there are no vaccines.
