The eight countries reporting Middle East respiratory syndrome coronavirus (MERS-CoV) cases through September 11, 2013 are color coded by frequency of reported cases in the map below. The numbers presented for all countries, with the exception of Saudi Arabia, are presumed to be accurate. The count from Saudi Arabia is uncertain due to poor case reporting from the Saudi Arabia Ministry of Health. The local cluster outbreaks in the countries of France, Italy, Tunisia, and the United Kingdom are a result of the human-to-human infection. In each of these country clusters, the index case had recently returned from a trip to the Middle East.
