摘要:

应用集中度和圆形分布法对保山市1990-2014年报告的疟疾疫情数据进行处理分析。结果表明,1990-2014年保山市的疟疾发病呈下降趋势,总集中度M=0.36,圆形分布r=0.30,平均角α=148.78°,显示保山市疟疾发病的高峰日为5月31日,流行期为3月2日~8月29日,与当地传疟媒介的季节性消长时间不一致。

Abstract:

The malaria epidemic data in Baoshan city from 1990 to 2014 were analyzed with concentration ratio and circular distribution. Results showed that the incidence of malaria in Baoshan city displayed a trend of decrease from 1990 to 2014. The total concentration ration M was 0.36, the circular distribution r was 0.30, and the average angle α was 148.78°. The malaria incidence peaked on May 31, with the epidemic period being from March 2 to August 29, which is inconsistent with the seasonal ebb and flow of local malaria vector.
