The results of Aedes larval surveys and Dengue Fever in the 4th Regional Health, 2017-2019

Abstract

Dengue is an important arboviral disease and still a major problem. No vaccine exists for dengue or specific treatment.The primary preventative measure to reduce dengue infections is the control of mosquito populations. Since 2017, the Office of Disease Prevention and Control 4th, Saraburi Province use the Tanrabad® application to assess risk of dengue transmission after conducting larva survey in the responsibility area. This study compiled the Aedes larvae index data from the Tanrabad® application and analyzed to study the prevalence of Aedes aegypti larvae and study the relationship of with dengue incidence in the year, 2017-2019. The results of the survey of Aedes Aegypti larvae breeding sites percentage of houses surveyed found the highest Aedes aegypti larvae (HI) accounted for 25.25% in 2011. The percentage of the container with the highest larvae (CI) was found as 6.96%. The number of containers found by larvae per 100 houses (BI), the highest 30.31%. The container survey showed that the most risk container were found in larvae in the whole year. 2017-2019 in the area of health region 4th, including containers that are not used accounted for 17 percent, followed by anti-ant plates, refrigerator/water cooler and old tires accounted for 15, 14 and 13 percent respectively. The results of the study on the relationship between the control of Aedes aegypti larvae and the incidence of disease showed that the incidence of dengue fever and Aedes aegypti larvae index (HI, CI and BI) were both provincial and in the overall health area. The fourth was not statistically significant at a confidence level of 0.05 (p-value> 0.05).
