【摘要】 目的探讨降雨量及水位对人群急性血吸虫病(急血)的影响,为控制急血提供预警预报。方法采用回顾性调查方法,收集东、南、西洞庭湖区域2003~2007年垸外水位和降雨量资料及急血资料进行相关分析。结果急血发病人数逐年下降,2007年较2003年下降95.37%,3年来无急血暴发流行,近5年急血发病高峰时段月平均降雨量逐年明显减少,急血发病与同期月平均水位高低相关。结论急血发病与水位涨落和降水量大小有着直接关系。坚持科学的防控措施,因地制宜,适时干预,则可有效减少急血发生。更多还原

【Abstract】 Objective To study the impact of precipitation and water level on acute schistosomiasis for providing reference to control acute schistosomiasis in advance. Methods The historical data on precipitation and water level as well as acute schistosomiasis from 2003 to 2007 in Eastern, Southern and Western Dongting Lake regions were collected and analysed for the correlation between acute schistosomiasis and precipitation and water level in local areas. Results Acute schistosomiasis gradually decreased year by year from 2003 to 2007. Compared with 2003, the number of acute schistosomiasis in 2007 reduced by 95.37%. There was no outbreak of acute schistosomiasis from 2005 to 2007.In the period of peak acute schistosomiasis, the average monthly rainfall reduced from year to year for the successive 5 years. There was a significantly correlation between acute schistosomiasis and monthly average water level. Conclusions The acute schistosomiasis is directly affected by nature factors and has a close correlation with the rainfall and water level in Dongting Lake regions.更多还原
