| 目的 描述黑龙江省新型冠状病毒肺炎（新冠肺炎）本土相关疫情的流行状况及特点，为黑龙江省新冠肺炎防控策略提供参考依据。方法 新冠肺炎个案调查、聚集性疫情调查资料来源于中国CDC全国传染病报告信息管理系统和突发公共卫生事件报告管理信息系统。采用Excel 2010和SPSS 23.0软件整理数据与统计学分析，描述人群、时间及地区分布特征。结果 2020年1月22日黑龙江省报告首例新冠肺炎确诊病例，截至2020年3月11日，13个城市累计报告境内病例482例，发病率为1.28/10万，病死率为2.70%（13/482）。其中聚集性疫情81起，确诊病例数占总确诊病例的79.25%（382/482），死亡12例；家庭聚集70起（86.42%，70/81）。与散发病例相比，聚集性疫情尤其是家庭聚集性病例中，病死率、≥60岁老年人与重/危重型的比例均较高，差异均无统计学意义（均P>0.05）。涉及病例≥5例的聚集性疫情占41.98%（34/81），涉及病例数占聚集性病例的68.31%（261/382），涉及6~9例病例数的聚集性疫情中，年龄≥65岁者的比例较多（26.53%，39/147）。结论 黑龙江省新冠肺炎的发病率较高，前期疫情较为严重；聚集性疫情尤其是家庭聚集涉及病例数较多。 |

| Objective To describe the COVID-19 epidemic and its characteristics in Heilongjiang province, and provide evidence for the further prevention and control of COVID-19 in the province. Methods The information of COVID-19 cases and clusters were collected from national notifiable disease report system and management information system for reporting public health emergencies of China CDC. The Software's of Excel 2010 and SPSS 23.0 were applied for data cleaning and statistical analysis on the population, time and area distributions of COVID-19 cases. Results On January 22, 2020, the first confirmed case of COVID-19 was reported in Heilongjiang. By March 11, 2020, a total of 482 cases domestic case of COVID-19, The incidence rate was 1.28/100 000, the mortality rate was 2.70% (13/482) in 13 municipalities in Heilongjiang. There were 81 clusters of COVID-19, The number of confirmed cases accounted for 79.25% (382/482) of the total confirmed cases and 12 cases of deaths. The family clusters accounted for 86.42% (70/81). Compared with the sporadic cases, the mortality rate, proportion of elderly cases aged 60 or above and severe or critical cases of clinical classification were all higher in the clusters especially the family clusters, but the differences were not significant (P>0.05). There were 34 clusters involving more than 5 confirmed cases accounted for 41.98% (34/81) of the total clusters, the involved cases accounted for 68.31% (261/382) of the total cases of clusters. There were significant differences in age distribution of the cases among the case clusters with different case numbers. In the clusters involving 6-9 cases, the proportion of cases aged 65 years or above was more (26.53%, 39/147).
