湖北省桐柏山及大别山区疟疾流行态势

目的掌握桐柏山及大别山区疟疾流行态势,分析流行因素,提出有效控制措施。方法收集桐柏山及大别山区1990-2007年各县（市）疟疾疫情、气象资料及调查资料,分析流行态势及因素。结果桐柏山区系中度不稳定疟疾流行区,疟疾回升间隔为8～9年,流行年发病率最高为28.35/10万,非流行年发病率最低为6.55/10万,传染源的积累是造成当地疟疾流行的主要因素,流行年疟疾发病与温度、降雨量密切相关,其高峰在降雨后1个月;大别山区系低度稳定疟疾流行区,年发病率在1/10万以下,连续10年以上无回升。结论桐柏山及大别山区疟疾现已降至1/万以下,大部分地区仅属残存病例,控制传染源是遏制疟疾回升的有效措施。

Evaluation of Malaria Epidemic Situation in Tongbai and Dabieshan Mountain Area in Hubei

Objective To understand the situation of malaria epidemic and analyze the epidemic factors in Tongbai and Dabie mountain area, and suggest effectiveness measures to control the disease. Methods The data of malaria cases and weather during 1990-2007 was collected in Tongbai and Dabie mountain area for the analysis of epidemic factors. Results Results showed unstable medium epidemic of malaria area interval 8-9 years in Tongbai mountain. The peak morbidity was 28.35/hundred thousands incidence in high epidemic years and 6.55/hundred thousands in lower epidemic years. The accumulation of infection source was the cause of malaria epidemics, the peak of malaria cases was correlated with temperature and precipitation of the year, with the peak at one month after rain season. In the malaria stable and low malaria epidemic area, the incidence had been under 1/hundred thousands and without any increase over 10 years in Dabie mountain. Conclusion The incidence rate of malaria in Tongbai and Dabieshan Mountain areas was under 1/ten thousands, and most areas only have few cases. Control the infectious sources of malaria was the effective measures to prevent the disease.
