摘要
目的了解并分析河南省2006年的疟疾疫情,评价疟疾防治措施,为疟疾防治提供依据。方法收集河南省2006年的疟疾疫情报告数据进行分析,评价防治措施。结果全省2006年共报告疟疾病例5 090例,平均年发病率为0.52%,较2005年的2 304例上升120.92%。病例集中在永城、夏邑和桐柏等15个县.共发生疟疾4 769例,占全省疟疾发病数的93.69%,较上年的2 085例上升128.73%。其中豫东地区的永城和夏邑两县上升幅度明显,分别较上年上升307.04%和360.94%。全省发现36个暴发点均分布在永城市,发病2 890例,占全省发病数的56.8%。全省2006年共血检发热病人332 853人,镜检阳性3 204例,阳性率为0.96%,占全部报告病例的62.95%。疟疾休止期服药15 470人,正规服药率97.12%。流行季节对疟疾高发区的8 567人进行了预防性服药。现症病人正规服药率95%。在暴发点采取全民预防服药11 953人次、菊酯类杀虫剂灭蚊室内外喷洒82万m^2等措施后控制暴发。结论河南省疟疾疫情处于快速回升状态,应当采取超常规措施防止豫东地区大范围疟疾暴发流行。
Objective To understand and analyze malaria situation in Henan Province in 2006, and evaluate the malaria control measures, and provide evidence for malaria control and prevention. Methods Data on malaria epidemic situation were collected and analyzed. Malaria control measures were evaluated. Results 5 090 malaria cases were reported and malaria incidence was 0. 529/10000 in Henan Province in 2006. The number of reported malaria cases in 2006 was 120.92% higher than 2 304 in 2005. Main malaria cases were distributed in 15 counties including Yongcheng, Xiayi, Tongbai, et al. 4 769 cases were reported in these counties, accounted for 93.69% of total cases in Henan Province and 128. 73% higher than 2 085 in 2005. All of 36 local malaria outbreak spots were found in Yongcheng county, of which 2 890 malaria cases were reported and accounted for 56.8% of total cases in Henan Province. 332 853 of fever patients were tested and 3 204 were positive with positive rate of 0.96%, account for 62.95% of total malaria cases. On malaria control measures in Henan Province, 15 470 of people with infection history in the last year and relative population （families and/or neighbors） were given pre-transmission season treatment, and the rate of proper treatment reached at 97.12%. During transmission season, oral preventive drugs were given to 8 567 high risk people. The rate of proper treatment reached at 95 % in the new diagnosed patients with vivax malaria and/or suspects. In outbreak spots of Yongcheng county, 11 953 of oral preventive drugs were given to the people in high risk areas, residual spray of decamethrin were used in 820 000 m^2 in and/or out of rooms, then malaria outbreaks were control. Conclusion Dramatic resurgence of malaria situation appeared in Henan Province. Supernormal malaria control measures should be done to prevent the possible wide-bound malaria outbreak in East of Henan Province.
