目的及时掌握绵竹市地震灾后病媒生物种类、密度动态,为病媒生物性疾病风险评估提供可靠依据,科学合理、及时有效的控制病媒生物,切断传染病传播途径,保护灾区人民健康。方法根据《汶川地震灾区病媒生物监测方案(试行)》要求,采用目测法监测蚊虫、蝇类密度;鼠迹法监测鼠类密度。结果绵竹市震后6-10月各监测点平均蚊虫密度为13.45只/人工.h,平均蝇类密度为0.23只/m2,平均鼠类密度为4.00处/2 000 m。结论地震后绵竹市6月、7月蚊?蝇?鼠密度较大,对灾区人民健康造成巨大隐患,8月份居民入住板房蚊?蝇?鼠密度明显下降,已达到不足为害水平。
OBJECTIVE To grasp the species and density dynamics of the vector after the earthquake in Mianzhu City in time, provide a reliable basis for the risk assessment of vector-borne diseases, and control the disease vector timely and effectively, cut off the transmission of infectious diseases and protect the health of people in the disaster areas. Methods According to the requirements of “vector bio-monitoring program in Wenchuan earthquake-affected area (for trial implementation)”, mosquito and flies density were monitored by visual inspection method; and mouse density was monitored by mouse trace method. Results The average mosquito density at each monitoring point in Mianzhu from June to October was 13.45 / h, the average flies density was 0.23 / m2 and the average rodent density was 4.00 / 2000 m. Conclusion Mianzhu mosquito density in June and July in Mianzhu City after the earthquake was relatively large, causing huge hidden danger to people’s health in the affected areas. In August, the density of mosquitoes and mosquitoes in boarding houses decreased significantly, which has reached the level of deficiency.
