摘　　要：目的了解2011—2019年河南省疟疾疫情特征,为河南省消除疟疾后监测阶段疟疾防控提供科学依据。方法收集2011—2019年河南省疟疾疫情资料及疟疾病例个案调查资料,采用描述流行病学方法对疟疾流行特征进行分析。结果 2011—2019年河南省共报告疟疾病例1 836例,其中有1 634例境外输入病例,15例境外输入性恶性疟病例死亡。境外输入病例来自非洲的有1 545例(94.55%,1 545/1 634),以恶性疟为主(81.10%,1 253/1 545);东南亚88例(5.39%,88/1 634),以间日疟为主(84.09%,74/88)。1 836例病例分布于全省18个市的128个县(市、区),报告病例数位于前五的市有郑州市(651例)、洛阳市(256例)、濮阳市(151例)、南阳市(138例)和安阳市(95例),占总病例数的70.32%。男性1 738例,女性98例;病例主要集中于20~59岁年龄组,占病例总数的93.74%(1 721/1 836),职业以农民为主。病例分布具有一定的季节性,2011—2019年发病7 d内确诊率差异具有统计学意义(χ~2=61.854,P <0.01)。18个市在发病后3 d和7 d内的确诊率差异均具有统计学意义。结论在全省进入消除后监测阶段,应继续严格按照"1-3-7"消除疟疾工作模式要求,完善消除后监测体系,以巩固来之不易的消除疟疾成果。Objective To ascertain the characteristics of malaria incidence inH enan Province from 2011 to 2019,and to provide scientific basis for the prevention and control of malaria in the monitoring stage after malaria elimination in Henan Province. Methods Data of malaria cases in Henan Province during 2011 to 2019 were collected from the Information Management System for Infectious Diseases Report and Information Management System for Parasitic Diseases Control and Prevention,and the descriptive epidemiological analysis was performed. Results A total of 1 836 cases of malaria were reported from 2011 to 2019,of which 1 634 cases were oversea imported and 15 deaths of imported P. falciparum were imported from abroad. 1 545 cases( 94. 55%,1 545/1 634) were from Africa,and the predominant cases were P. falciparum( 81. 10%,1 253/1 545). 88 cases( 5. 39%,88/1 634) were from Southeast Asia,mainly P. vivax( 84. 09%,74/88). All1 836 cases were distributed in 128 counties. The top five cities with reported cases were Zhengzhou( 651),Luoyang( 256),Puyang( 151),Nanyang( 138) and Anyang( 95),accounting for 70. 32% of the total cases in Henan Province. Most malaria cases were adults,of which 1 738 cases were male and 98 cases were female,while 1 721 cases( 93. 74%) were at ages of 20 to 59 years. Farmers were the predominant occupation and the distribution had certain seasonality. The difference in the diagnosis rate within 7 days from 2011 to 2019 was statistically significant( χ2= 61. 854,P < 0. 01). The difference in diagnosis rate within 7 days after onset in 18 cities was statistically significant. Conclusion As Henan has entered in the post-elimination monitoring stage,the"1-3-7"malaria elimination work model should be carried out strictly and the monitoring system should be improved to consolidate the achievement of malaria elimination.
