Since 2012, a total of 2583 laboratory-confirmed cases of Middle East respiratory syndrome (MERS), including 890 associated deaths were reported globally for a case-fatality ratio (CFR) of 34.4%. The majority of these cases were reported from Saudi Arabia, which had 2182 cases including 812 related deaths (CFR 37.2%).
The World Health Organization (WHO) says MERS-CoV is a virus transferred to humans from infected dromedary camels. It is a zoonotic virus, meaning it is transmitted between animals and people, and it is contractable through direct or indirect contact with infected animals. MERS-CoV has been identified in dromedaries in several countries in the Middle East, Africa and South Asia. In total, 27 countries have reported cases since 2012.
Human-to-human transmission is possible, but only a few such transmissions have been found among family members living in the same household. In health care settings, however, human-to-human transmission appears to be more frequent.
