摘要
目的分析2020年浙江省法定传染病流行特征,为浙江省传染病防控工作提供依据。方法通过中国疾病预防控制信息系统传染病监测系统收集2015—2020年浙江省法定传染病报告资料,采用描述流行病学方法分析2020年浙江省法定传染病发病及死亡情况,并与2015—2019年均值比较;分析新型冠状病毒肺炎、流行性感冒、其他感染性腹泻等传染病的流行特征。结果2020年浙江省报告法定传染病30种,病例487271例,报告发病率为832.94/10万,死亡率为0.6154/10万,分别较2015—2019年均值下降7.05%和14.60%。甲、乙类传染病周发病率为1.24/10万~3.68/10万,第6—8周出现1个发病低谷;丙类传染病第1周发病率为154.19/10万,在第2—6周快速下降至4.83/10万,之后维持在较低水平。杭州市、金华市和宁波市发病率较高,分别为1412.62/10万、960.35/10万和921.25/10万;其中杭州市丙类传染病发病率为1248.80/10万,高于其他10个市。报告发病率较高的传染病有流行性感冒、其他感染性腹泻、手足口病、肺结核、梅毒和病毒性肝炎,分别为438.45/10万、140.29/10万、99.64/10万、41.92/10万、41.37/10万和30.48/10万;报告死亡率较高的传染病主要为艾滋病和肺结核,分别为0.4821/10万和0.1162/10万。报告新型冠状病毒肺炎确诊病例1306例,无症状感染者302例,死亡1例。结论2020年浙江省法定传染病发病率较2015—2019年均值下降,肺结核、梅毒和乙肝仍然高发,新发的新型冠状病毒肺炎疫情波及范围广,部分呼吸道传染病和输入性传染病发病率较往年明显下降。
Objective To analyze the epidemiological characteristics of notifiable infectious diseases reported in Zhejiang Province in 2020 for prevention and control.Methods Data of notifiable infectious diseases reported in Zhejiang Province in 2020 were extracted from China Information System for Disease Control and Prevention.The incidence and death of notifiable infectious diseases were analyzed and compared with the averages from 2015 to 2019;then the characteristics of some key diseases such as coronavirus disease 2019(COVID-19),influenza and other infectious diarrhea were summarized.Results Totally 487271 cases of 30 kinds of infectious diseases were reported.The incidence and mortality rate was 832.94/100000 and 0.6154/100000,which were 7.05%and 14.60%lower than the average value of 2015-2019.The weekly morbidity of Class A and Class B infectious diseases fluctuated between 1.24/100000 and 3.68/100000,and hit the bottom in the sixth to eighth week.The morbidity of Class C infectious diseases was 154.19/100000 in the first week,then dropped to 4.83/100000 in the second to sixth week and maintained at a low level.High morbidity of infectious diseases were reported in Hangzhou(1412.62/100000),Jinhua(960.35/100000)and Ningbo(921.25/100000).The morbidity of class C infectious diseases in Hangzhou was 1248.80/100000,which was far higher than that of other ten prefecture-level cities.The diseases with high reported morbidity were influenza(438.45/100000),other infectious diarrhea(140.29/100000),hand-foot-and-mouth disease(99.64/100000),pulmonary tuberculosis(41.92/100000),syphilis(41.37/100000)and viral hepatitis(30.48/100000).More deaths were reported in AIDS and pulmonary tuberculosis,and the mortality were 0.4821/100000 and 0.1162/100000.A total of 1306 confirmed cases,302 asymptomatic infections and 1 death of COVID-19 were reported.Conclusion In 2020,the incidence rate of notifiable infectious diseases in Zhejiang decreased compared with the average value of 2015-2019.Pulmonary tuberculosis,syphilis and hepatitis B still have high morbidity,and the COVID-19 epidemic spread widely.The morbidity of some respiratory infectious diseases and imported infectious diseases have dropped significantly compared with previous years.
