A β-coronavirus, MERS-CoV is a member of the large viral family that includes the SARS coronavirus as well as viruses that cause the common cold (WHO, 2014b). MERS-CoV appears to be circulating widely throughout the Ara-bian Peninsula, where all primary cases to date apparently became infected. While some secondary cases of MERS—including several large hospital outbreaks30—have arisen, the virus does not appear to be readily transmissible (WHO, 2014b). Intensive screening of MERS-CoV contacts revealed very few instances of house-hold transmission (WHO, 2014d). Secondary cases tend to present with a milder disease than primary cases, and many of the recently reported secondary cases have been mild, or were people whose tests were positive for MERS-CoV but were asymptomatic.
