An ongoing outbreak of pneumonia associated with 2019 novel coronavirus was reported in China. It is unclear whether the virus is infective exists during the incubation period, although person-to-person transmission has been reported elsewhere. We report the epidemiological features of a familial cluster of 4 patients in Shanghai, including an 88-year-old man with limited mobility who was exposed only to asymptomatic family members whose symptoms developed later. The epidemiological evidence has shown possible transmission of 2019 novel coronavirus during the incubation period.
中国报告了一起与 2019 年新型冠状病毒相关的肺炎疫情爆发。目前尚不清楚该病毒在潜伏期是否具有传染性,尽管其他地方已经报告了人际传播的情况。我们报告了上海一家族性聚集性病例的流行病学特征,包括一名 88 岁行动受限的男子,他仅接触过后来出现症状的无症状家庭成员。流行病学证据表明,2019 年新型冠状病毒在潜伏期可能具有传染性。
