目的为了更有效地预防登革热的流行,建立基于伊蚊监测诱蚊诱卵法的登革热可能流行分级预警指标体系。方法根据伊蚊的生态特点建立诱蚊诱卵法,比较诱蚊诱卵指数(MOI)与传统的登革热媒介监测的布雷图指数(B)I和诱卵指数的关系,并结合此法在登革热流行监测中的实际应用效果,参照国内外的登革热可能流行分级控制体系和其他相关的虫媒疾病分级控制体系,初步建立基于诱蚊诱卵法的登革热可能流行的分级预警指标。结果将MOI分为4个层次:<5、5～20、20～40和>40,并结合登革热流行的季节特点、蚊虫携带病毒以及疫情监测结果,分成4个登革热流行预警级别,提出相应的媒介控制措施。结论MOI<5可作为登革热疫情得到有效控制的指标。分级预警与应对指标仍有待实际应用的进一步检验和研究。
Objective To prevent the epidemic of dengue more effectively and to establish the epidemic prehistoric epidemic index system based on Aedes albopictus monitoring of mosquito and egg. Methods Based on the ecological characteristics of Aedes albopictus, the method of establishing mosquito and oviposition was established to compare the relationship between the mosquito-oviposition index (MOI) and the traditional Bovine index (B) I and the index of ovulation induced by dengue vector monitoring. Epidemiological surveillance, and according to the epidemic grading control system of dengue fever in other countries at home and abroad and other related insect disease control systems, the preliminary warning index of dengue fever that may be prevailing based on the method of mosquito and ovum induction was initially established. Results MOI was divided into four levels: <5, 5-20, 20-40 and> 40. According to the seasonal characteristics of dengue epidemic, mosquito-borne virus and surveillance results of epidemic situation, MOI was divided into four epidemic warning levels of Dengue, Media control measures. Conclusion MOI <5 can be used as an indicator of effective control of dengue fever. Grading early warning and response indicators are yet to be further tested and studied.
