Abstract
As of July 14, 2015, the South Korean outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) infection has involved 185 secondary infections belonging to three overlapping generations of cases who have contracted the virus almost exclusively in the healthcare environment. Fomite transmission may explain a significant proportion of the infections occurring in the absence of direct contact with infected cases. The analysis of publicly available data collected from multiple sources, including the media, is useful for describing the epidemic history of an infectious disease outbreak.

Three generations of secondary infection, with over half belonging to the second generation, could be delineated. Hospital infection was found to be the most important cause of virus transmission, affecting largely non-healthcare workers (154/184).
