目的 比较环境卫生治理和化学灭蚊对蚊媒密度的控制效果,为有效防治登革热提供科学依据.方法 收集2020年广州市海珠区老旧城区试点的布雷图指数(breteau index,BI)、成蚊密度指数(adult mosquito density index,ADI)、标准间指数(standard space index,SSI)和诱蚊诱卵器指数(mosquito ovitrap index,MOI)原始数据,根据以上蚊媒指标进行蚊媒密度风险分级,对环境卫生治理组、化学灭蚊组干预后的蚊媒密度的风险等级数据资料进行卡方检验.结果 干预期后,环境卫生治理组与对照组蚊媒密度风险等级分布差异有统计学意义(x2=11.14,P＜0.05),化学灭蚊组与对照组蚊媒密度风险等级分布差异无统计学意义(x2=1.57,P＞0.05),环境卫生治理组与化学灭蚊组蚊媒密度风险等级分布差异有统计学意义(x2=6.94,P＜0.05).结论 环境卫生治理干预措施对降低蚊媒密度具有持续性效果,能达到有效防控登革热的目标.
Objective To compare the control effects of environmental sanitation management and chemical mosquito control on mosquito vector density,and to provide a scientific basis for effective prevention and control of dengue fever.Methods The original data of breteau index(BI),adult mosquito density index(ADI),standard space index(SSI)and mosquito ovitrap index(MOI)were collected from Haizhu old district pilot in Guangzhou City in 2020.Risk classification of mosquito vector density was carried out according to the above mosquito vector indicators,and Chi-square test was carried out on the risk class data of mosquito vector density after the intervention of environmental sanitation management group and chemical mosquito control group.Results After the intervention period,the difference in risk class distribution of mosquito vector density between the environmental sanitation management group and the control group was statistically significant(x2=11.14,P＜0.05),while the difference in risk class distribution of mosquito vector density between the chemical mosquito control group and the control group was not statistically significant(x2=1.57,P＞0.05),and the difference in risk class distribution of mosquito vector density between the environmental sanitation management group and the chemical mosquito control group was statistically significant(x2=6.94,P＜0.05).Conclusion Environmental sanitation management interventions have a sustained effect on reducing mosquito vector density and can achieve the goal of effective prevention and control of dengue fever.
