苏、鲁、豫、皖、鄂五省2006年疟疾疫情分析

目的分析苏鲁豫皖鄂五省2006年疟疾流行情况，评价我国中部地区五省疟疾防治措施。方法收集苏鲁豫皖鄂五省2006年疟疾疫情报告、媒介监测、发热病人血栓、血清学调查和防治措施进行分析。结果五省2006年共报告疟疾病例42744例，占全国疟疾发病的67％，平均发病率1．13／万，比2005年上升109．8％。病例主要分布于安徽和河南两省，报告病例40008例，占五省病例总数的93．6％。输入性疟疾病例458例，其中输入性恶性疟56例。2006年传播休止期治疗9．4万人，流行李节服药治疗11.6万人，治疗疟疾现症病人和疑似病人51907人次，实施药物滞留喷洒或杀虫荆浸帐灭蚊保护人口13，6万人。血栓发热病人161．22万人次，阳性者21889人，阳性率1．36％，占全部报告病例的51．2l％。抗体阳性率1．79％（24／13454）；居民带虫阳性率0．32％（134／41534）。结论五省尽管采取有力的防治措施，但疟疾疫情仍呈回升态势，疟防工作仍十分艰巨。

Analysis of malaria situation in five provinces of Jiangsu, Shandong, Henan, Anhui and Hubei in 2006

Objective To analyze malaria situation in five provinces of Jiangsu, Shandong, Henan, Anhui and Hubei in central China in 2006 and evaluaate malaria control measures. Methods Data coneertrning malaria infection , vector monitoring, blood examination of feverish eases, serological monitoring and malaria control measures implemented were collected and analyzed. Resnlts There 42 744 malaria eases were reported with an average incidence of 1.13 per ten thousand in the five provinces in 2006. The humber of reported malaria eases in 2006 increased 109.8% than that of previous year and it was accounted for 67.0 of the total eases in China. Most of malaria eases were distributed in Anhui and Henan Provinces in which 40 008 eases were reported accounted for 93.6% of the total eases detected in the five provinces. There were 458 imported eases including 56 faleiparum malaria cases. In 2006 94 0130 eases with malaria history were treated at transmission resting season with ehloroquine and primaquine. During transmission season a population of 116 000 people at high risk in areas with high incidence were treated ; there 51 907 diagnosed and suspected malaria cases were treated. Residul spraying of insecticide or insecticide - impgranting of bed nets were carried out and 136 0130 people were protected. Blood examination of 1 612 200 feverish cases were accomplished and 21 889 positives were detected with a positive rate of 1.36% accounted for 51.21% of the total cases reported. Antibody positive rate was 1.79% （24/3 454） and the parasite carrying rate in the inhabitants was 0.32% （134/41 534）. Conclusion The malaria control measures implemented in the five provinces are effective but malaria infection show an increasing tendency. Thus the work of malaria control is still a hard task to be performed.
