目的分析西南地区新型冠状病毒肺炎(NCP)疫情的流行病学特征及疫情期间公众的网络关注点。方法收集2020年1月21日至2月9日国家卫生健康委员会公布的疫情数据,并进行统计描述与分析;利用百度词条搜索指数初步分析西南地区包括四川省、重庆市、西藏自治区、贵州省、云南省疫情期间群众的网络关注点,用Origin 9软件绘制搜索指数热图。结果截至2020年2月9日,西南地区NCP累计确诊患者1070例,累计发病率为0.53/10万,累计治愈出院565例,死亡32例;西南地区累计确诊病例主要集中在重庆市(446例,占41.68%)和四川省(386例,占36.07%),西藏最少(仅有1例,占0.09%),日新增病例总体呈下降趋势。疫情期间,西南地区有关疫情进展和个人防护的百度搜索指数显著增高,分别以“疫情地图”和“口罩”两个词条的百度搜索指数最高,而与健康状况自评相关的“新冠肺炎症状”的百度搜索指数较低。结论2020年1月21日至2月9日,西南地区NCP疫情进展相对平缓,无病例急剧增加现象,防控措施有效,但不同地区疫情流行程度有明显的差异。加强疫情监测,严格控制人口流动,加强疫情防控信息的公布力度,增强公众自我保护意识和健康自测意识,有利于及时发现新发病例,实现群防群治。
ObjectiveTo analyze the epidemiological characteristics and network focus of novel coronavirus pneumonia (NCP) epidemic in Southwest China. MethodsEpidemic data released by the National Health Commission from 21st January to 9th February, 2020, was collected, statistically interpreted and analyzed. Search indexes by Baidu entries was employed to initially analyzed the public network focus in Southwest areas. including Sichuan province, Chongqing City, Tibet Autonomous Region, Guizhou province and Yunnan province during epidemic, and with Origin 9 software to draw a heat map of search indexes. ResultsDuring the period from 21st January to 9th February, 2020, the cumulative confirmed cases of NCP in Southwest areas were 1070 in total. The incidence of cumulative onset was 0.53 parts per hundred thousand. The cumulative cured cases were 565 and dead cases in 32. The cumulative confirmed cases were mainly centralized in Chongqing City (446 cases, 41.68%) and Sichuan Province (386 cases, 36.07%), Whereas Tibet had the lowest number of cases (only 1 case, 0.09%). The daily newly confirmed cases presented a descending trend in total. During epidemic, the search indexes via Baidu of relative epidemic advance and individual protection significantly increase, with the highest search indexes via Baidu in “epidemic map” and “mask”, respectively; whereas with lower search indexes related to health status self-assessment in “NCP symptoms”. ConclusionThroughout 21st January to 9th February, 2020, the advance of NCP epidemic in Southwest areas is relatively gentle, with no sharp increase of confirmed cases, which indicates an effective prevention and control measures; however, there is a prominent difference of epidemic status between various areas. It is conducive to discovering newly confirmed cases in time and to implementing prevention and treatment in mass by strengthening epidemic surveillance, strictly controlling movement of population, strengthening efforts to release the epidemic prevention and control information, raising awareness of public self-protection and healthy self-assessment.
