摘要
目的 分析2013—2020年张家港市境外输入性疟疾的特点,为今后防控策略和措施的制定提供科学依据。方法 收集2013—2020年张家港市境外输入性疟疾病例相关流行病学资料进行统计学分析。结果 2013—2020年张家港市共报告境外输入性疟疾病例52例,其中恶性疟35例(67.31%)、卵形疟13例(25.00%)、间日疟2例(3.85%)、三日疟2例(3.85%)。除2例间日疟病例来自大洋洲外,其余全部来自非洲国家。经圆形分布分析显示张家港市境外输入性疟疾病例季节性差异无统计学意义(Z=0.357 8,P>0.05)。地区分布以金港镇为主,共33例。病例以男性为主,女性仅2例;除1例病例为2岁外,其余均为20~57岁;职业发病最多的为木材行业,共36例。发病-初诊时间间隔中位数为2 d,平均值为2.33 d;初诊-确诊时间间隔中位数为0 d,平均值为0.88 d;出国-回国时间和发病次数差异有统计学意义,且存在线性递增趋势(χ^(2)=15.257,P<0.05;Z=13.501,P<0.01)。结论 2013—2020年张家港市境外输入性疟疾引起本地再传播的风险依然存在,要有针对性地加强疟疾防控,防止输入再传播。
Objective To analyze the characteristics of overseas imported malaria cases in Zhangjiagang City from 2013 to 2020,and to provide a scientific basis for the formulation of prevention and control strategies and measures in the future.Methods The related epidemiological data of imported malaria cases from abroad in Zhangjiagang City from 2013 to 2020 were collected for statistical analysis.Results From 2013 to 2020,Zhangjiagang City reported a total of 52 cases of imported malaria from abroad, including 35 falciparum malaria(67.31%),13 ovale malaria(25.00%),2 tertian malaria(3.85%) and 2 quartan malaria(3.85%).All the cases were from African countries, except for 2 cases of tertian malaria from Oceania.There was no statistical significance in seasonal distribution of imported cases in Zhangjiagang by circular distribution analysis(Z=0.357 8,P>0.05).The regional distribution was dominated by Jingang Town, with 33 cases.The imported cases were mainly male, with only 2 female cases.Except for 1 case, which was 2 years old, the others were between 20 and 57 years old;the largest number of occupations was in the timber industry, with 36 cases.The median time interval between onset and initial diagnosis was 2 d(mean 2.33 d);the median time interval between initial diagnosis and diagnosis was 0 d(mean 0.88 d).The differences in time abroad-return and number of episodes were statistically significant and there was a linear increasing trend(χ^(2)=15.257,P<0.05;Z=13.501,P<0.01).Conclusion The risk of local retransmission due to imported malaria from abroad still exists in Zhangjiagang from 2013 to 2020,and malaria prevention and control should be strengthened in a targeted manner to prevent imported malaria cases retransmission.
