INTERPRETATION: Our results showed increased transmission potential of MERS-CoV from a single patient in an overcrowded emergency room and provide compelling evidence that health-care facilities worldwide need to be prepared for emerging infectious diseases. Excluding three patients with confi rmed MERS-CoV infection who were not identifi ed in the initial patient contact investigation (appendix p 5), the overall attack rate for patients in the emergency room was 4% (30 of 675). No MERS-CoV infection was reported in patients and visitors who had been in the emergency room on May 29 during the time period when they were exposed only to zones II (n=81) or III (n=15), while Patient 14 was confi ned to zone IV. ./cache/cord-295971-jtv1jj2z.txt ./txt/cord-295971-jtv1jj2z.txt
