From May through July 2015, a total of 26 cases of Middle East Respiratory Syndrome were reported from 2 hospitals in Daejeon, South Korea, including 1 index case and 25 new cases. We examined the epidemiologic features of these cases and found an estimated median incubation period of 6.1 days (8.8 days in hospital A and 4.6 days in hospital B). The overall attack rate was 3.7% (4.7% in hospital A and 3.0% in hospital B), and the attack rates among inpatients and caregivers in the same ward were 12.3% and 22.5%, respectively. The overall case-fatality rate was 44.0% (28.6% in hospital A and 63.6% in hospital B). The use of cohort quarantine may have played a role in preventing community spread, but additional transmission occurred among members of the hospital cohort quarantined together. Caregivers may have contributed in part to the transmission.
2015 年 5 月至 7 月，韩国大田市的两家医院共报告了 26 例中东呼吸综合征病例，包括 1 例输入性病例和 25 例本地感染病例。我们对这些病例的流行病学特征进行了分析，估计潜伏期中位数为 6.1 天（A 医院为 8.8 天，B 医院为 4.6 天）。总感染率为 3.7%（A 医院为 4.7%，B 医院为 3.0%），同一病房住院患者和陪护人员的感染率分别为 12.3%和 22.5%。总病死率为 44.0%（A 医院为 28.6%，B 医院为 63.6%）。采用队列隔离的方法可能有助于防止社区传播，但在集中隔离的医院队列人群中仍发生了后续传播。陪护人员可能在一定程度上促成了传播。
