South Korean health officials on Sunday reported 14 more cases of Middle East Respiratory Syndrome, bringing the total in the country’s outbreak to 64, and said a fifth person infected with the virus had died. South Korea’s outbreak of the often-deadly MERS virus, first reported on May 20, is the largest outside the Middle East, prompting public fear and questions over the government’s initial response. The patient who died was a 75-year-old man who had been in the same Seoul hospital emergency room where a total of 17 people, including two medical staff, are believed to have been infected with MERS, South Korea’s health ministry said.
