【摘要】 目的 分析COVID-19疫情对广州市输入性疟疾防控的影响，为新发传染病发生时输入性疟疾的防控工作提供参考。方法 收集2017—2022年广州市输入性疟疾资料，分析疟疾特征和疫情调查处置情况，采用χ~2检验、Fisher确切概率法、秩和检验和Brown-Mood检验进行统计检验。结果 2017—2022年广州市报告输入性疟疾病例602例，平均年龄(39.79±10.95)岁，以中国籍(480例，占79.73%)、男性(531例，占88.21%)和劳务工人(313例，占51.99%)为主，疟疾类型以恶性疟为主(526例，占87.38%)。COVID-19疫情后(2020—2022年)报告疟疾病例274例，较COVID-19疫情前(2017—2019年)减少16.46%;COVID-19疫情前后，疟疾病例在不同性别、年龄、国籍、职业和病例来源地方面，占比差异有统计学意义(χ~2=19.31、28.73、87.74、24.13,P<0.001)。COVID-19疫情后，疟疾病例的发病-初诊时间间隔分布及中位数、7d内疫点调查处置率均优于COVID-19疫情前，差异有统计学意义(W/Z=61 269.00、32.51,P<0.001)。结论 在COVID-19疫情防控过程中，广州市采取的措施有助于强化执行“1-3-7”工作规范，能有效阻止输入性疟疾疫情的传播和扩散。更多还原

【Abstract】 Objective To analyse the impact of the COVID-19 epidemic on the prevention and control of imported malaria in Guangzhou City, and to provide a reference for informing the prevention and control of imported malaria in the event of emerging infectious diseases occurrence.Methods Data on imported malaria cases in Guangzhou City from 2017 to 2022 were collected.The characteristics and survey and disposal of malaria epidemic were analyzed.The Chi-square test, Fisher exact probability method, rank-sum test and Brown-Mood test were used for statistical testing.Results A total of 602 imported malaria cases were reported in Guangzhou City from 2017 to 2022,the average age was 39.79±10.95 years old.The majority of cases were Chinese nationals(480 cases, 79.73%),males(531 cases, 88.21%),and labor workers(313 cases, 51.99%),and the main type of malaria was falciparum malaria(526 cases, 87.38%).Two hundred and seventy-four imported malaria cases were reported after the COVID-19 epidemic(2020-2022),a decrease of 16.46% compared to the period before COVID-19 epidemic(2017-2019).The differences in the percentage of malaria cases before and after the COVID-19 epidemic based on gender, age, nationality, occupation and place of region of cases were statistically significant(χ~2=19.31,28.73,87.74,24.13,P<0.001).After the COVID-19 epidemic, the distributions and median on distribution of onset-preliminary diagnosis time intervals of malaria cases, as well as investigation and disposition rate of epidemic spot within 7 days were better than those before the COVID-19 epidemic, with a statistically significant(W/Z=61 269.00,32.51,P<0.001).Conclusion The measures implemented in Guangzhou City during the prevention and control of the COVID-19 epidemic help to strengthen the implementation of the "1-3-7" job specification and effectively stop the transmission and diffusion of imported malaria epidemics.更多还原
