目的了解成都市疟疾疫情状况,为有针对性地开展消除疟疾工作提供科学依据。方法对2012-2016年成都市报告的输入性疟疾病例数据进行回顾性分析。结果 2012-2016年成都市报告疟疾病例全部为输入性病例,共240例,其中恶性疟165例(68.75%)、间日疟49例(20.41%)、三日疟6例(2.50%)、卵形疟16例(6.25%)、混合感染5例(2.08%),死亡3例,病死率为1.25%;自非洲输入224例,东南亚输入16例。平均年发病率为0.28/10万,年间发病率差异有统计学意义(χ~2=23.87,P<0.001)。各月份均有病例报告,无明显季节性(χ~2=0.833,P>0.05)。结论成都市境外输入性疟疾病例呈上升趋势,应加强对境外输入性疟疾的防控工作,巩固消除疟疾成果。
Objective To understand the status of malaria in Chengdu and provide a scientific basis for targeted malaria elimination. Methods The data of malaria cases imported from Chengdu in 2012-2016 were analyzed retrospectively. Results A total of 240 malaria cases were reported in Chengdu in 2012-2016, including 165 malaria cases (68.75%), 49 malaria cases (20.41%), 6 malaria cases (2.50%), There were 16 cases of oval malaria (6.25%), 5 cases of mixed infection (2.08%) and 3 deaths, with a mortality rate of 1.25%; 224 cases were imported from Africa and 16 cases were imported from Southeast Asia. The average annual incidence was 0.28 / 100 000, with significant difference in the annual incidence (χ ~ 2 = 23.87, P <0.001). Each month, there are case reports, no significant seasonal (χ ~ 2 = 0.833, P> 0.05). Conclusion The incidence of imported malaria outside Chengdu is on the rise. The prevention and control of imported malaria should be strengthened and the results of malaria elimination should be consolidated.
