目的 分析新型冠状病毒肺炎疫情响应期间,芜湖市其他法定传染病监测的发病情况。方法 采用描述性分析方法,比较2020年新型冠状病毒肺炎疫情不同响应阶段其他法定传染病发病情况,采用2017—2019年移动平均数水平分析方法,描述新冠肺炎疫情背景下的其他法定传染病发病水平的变化。结果 2020年芜湖市法定传染病报告发病数较2019年下降26.70%,响应前期高于2019年同期水平,一级、二级响应期间、常态化防控期间均低于2019年同期水平。发病前10位的法定传染病在一级二级响应期间较2019年同期下降了54.63%,其中手足口病、流行性感冒、丙型肝炎、其他感染性腹泻等四种传染病报告发病数下降在50%以上。与2017—2019年5日移动平均数对比,2020年流行性感冒发病水平较低,手足口病春夏之交流行高峰未出现,但秋冬季高峰明显,成为当年发病主高峰,其他感染性腹泻的发病除一级二级响应期间明显低于既往水平外,常态化防控期发病水平及变化趋势与前3年发病情况类似。结论 新冠肺炎疫情期间的防控措施对其他传染病尤其是急性传染病同样起到了一定程度的阻断传播作用,对于流感等与新冠肺炎传播途径相近的传染病更为明显。

Objective To analyze the incidence of other legal infectious diseases in Wuhu City during the epidemic period of COVID-19. Methods Descriptive analysis was used to compare the incidence of other legal infectious diseases in different stages of COVID-19 in 2020.Describe the changes in the incidence of other legal infectious diseases during the period of COVID-19 by the moving average analysis method in 2017 to 2019 year. Results The number of reported cases of legal infectious diseases in Wuhu City in 2020 decreased by 26.70% compared with that in 2019.The number of reported cases in 2020 was higher than that in the same period in 2019 in the early response period,and lower than that in the same period in 2019 in the first and second response periods and normalized prevention and control periods.The top ten legal infectious diseases decreased by 54.63% during the primary and secondary response period compared with the same period in 2019.Among them,hand-foot-and-mouth disease,influenza,hepatitis C and other infectious diarrhea reported decreased by more than 50%.Compared with the 5-days mobile average in 2017-2019 years,the incidence of influenza in 2020 was relatively low,and the epidemic peak of hand-foot-and-mouth disease did not appear in spring and summer,but the peak was obvious in autumn and winter,which became the main peak of hand-foot-and-mouth disease in that year.Except that the incidence of other infectious diarrhea during the primary and secondary response period was significantly lower than the previous level,the incidence level and change trend in the normalized prevention and control period were similar to those in the previous three years. Conclusion The COVID-19 prevention and control measures also play a certain role in the transmission of other infectious diseases,especially acute infectious diseases.Influenza and other infectious diseases similar to the transmission route of COVID-19 are more obvious.
