摘要
目的探讨疟疾防治中联合管理的作用。方法采用主动侦查与被动侦查相结合的方式,对临床诊断和实验室诊断病例进行个案调查。结果参与疟疾联防的五个地级市2005年共发现疟疾病例119例(占全省病例的63.30%),年发病率0.03/万。五市当地居民血检阳性率为0.05%,流动人口血检阳性率为0.14%,两者血检阳性率有显著性差异(!2=20.848,P<0.05);流动人口中的返乡人员血检阳性率为0.20%,外来人员血检阳性率为0.15%,经统计学检验,两者血检阳性率无显著性差异(!2=0.899,P>0.05)。在返乡人员中,从国外返乡的人员血检阳性率最高,与从其它省返乡的人员血检阳性率比较有显著性差异;参与疟疾联防的五个地级市全年各月都有疟疾病例发生,其中6、7月达到最高峰,病例的季节分布与我省传疟媒介的季节消长相吻合。结论通过联防,2005年我省联防区内疟疾发病率继续维持在低水平,输入病例和输入继发病例减少,流动人口疟疾发病得到了有效控制。
Objective To understand the effectiveness of joint prevetion for malaria control in Guangdong. Method Active survey and passive survey were carried out to investigate clinically and lab confirmed malaria cases. Result 119 malaria cases, account for 63.30% of all cases of the province, were identified in the 5 cities of the joint prevention area of Guangdong Province. Annum incidence rate of malaria was 0.03 per 10000. Positive rates of blood test for local population and floating population in the 5 cities were 0.05% and 0.14%, respectively, and showed a significant difference （x^2=20.848,P 〈 0.05）. The positive rates of blood test for persons who returned from outside and non-residents were 0.20% and 0.15%, respectively, and showed no significant difference （x^2=0.899, P 〉 0.05）. The positive rate of blood test for persons who returned from oversea was the highest, and was significantly different from that of the people returned from other provinces. Malaria cases occurred in every month of the year in the 5 cities, and was peaked at June and July. The season distribution of malaria cases was correlated with the changes in the population of malaria vectors. Conclusion By joint prevention for malaria in the 3 provinces, the malaria incidence rate of the 5 cities maintained at low level, imported cases and secondary transmitted cases decreased, and malaria of floating population was effectively under control.
