基于Python对深圳市新冠病毒感染者住院诊疗数据的挖掘研究

Research on the Diagnosis and Treatment Date of COVID-19 Patients in Shenzhen Based on Python

目的:通过对深圳市新冠病毒感染者诊疗数据的分析,比较2020年1月至2022年3月新冠病毒感染者临床特征,寻找新冠病毒感染者病情变化规律。方法:采用Python程序设计工具,对专病数据预处理,筛选出1668条有效治疗记录数据分析,采用χ^(2)检验比较治疗数据以寻找其差异变化,K-means聚类模型分析,并可视化直观展示,比较不同新冠病毒株临床表现,归纳深圳市2022年以来新冠病毒奥密克戎毒株的致病特点。结果:深圳2022年新冠病毒奥密克戎BA.2株传播速度快,但毒性弱,重症率低,复阳人员总体病情较轻,较2020年经典新冠病毒株复阳率低,但平均复阳间隔天数缩短。结论:定期采用数据挖掘手段对新冠病毒感染者诊疗数据追踪分析,可发现不同时期、不同新冠病毒毒株感染者病情演变规律,为新冠病毒疫情防控提供科学的决策依据。此外少年感染人数及比率显著上升,其中愈后少年复阳者大多在1周内二次感染,推断这段时间是易感期,要加强宣传提高安全意识,注意病毒防护。

Objective Through the analysis of the diagnosis and treatment data of coronavirus disease 2019(COVID-19)infected people in Shenzhen,the clinical characteristics of COVID-19 patients from January 2020 to March 2022 were compared to find out the changing rules of the disease conditions of COVID-19 patients.Methods The Python programming tool was used to preprocess the data of specific diseases,and 1,668 effective treatment records were selected for analysis.Theχ^(2)test method was used to compare the treatment data to find the differences.The K-means clustering model was analyzed and visually displayed to compare the clinical manifestations of different novel coronavirus strains.To summarize the pathogenic characteristics of Omicron strain of COVID-19 in Shenzhen since 2022.Results The transmission rate of Shenzhen 2022 COVID-19 Omicron BA.2 was fast,but the virulence was weak,the rate of severe illness was low,and the overall condition of the patients who relapse positive was relatively mild,which was lower than that of the classic COVID-19 strain in 2020,but the average number of days between relapse positive was shortened.Conclusion Regular data mining is used to track and analyze the diagnosis and treatment data of COVID-19 patients,which can discover the evolving rules of the disease of patients with different COVID-19 strains in different periods,providing scientific decision-making basis for the prevention and control of COVID-19.In addition,the number and rate of adolescent infection increased significantly,and most of the adolescents who recovered from the disease were infected again within 1 week,suggesting that this period is a susceptible period.Therefore,it is necessary to strengthen the publicity,improve the awareness of safety,and pay attention to virus protection.
