4.3. Correlation of vector index with dengue patients in Dien Khanh district 2015-2017 period There is no correlation between the mosquito density index and the average number of dengue cases in the period 2015-2017 in Dien Khanh district. Other indicators of mosquitoes and larvae did not correlate with the number of dengue cases. The results of correlation analysis in Dien Khanh differ from the study of author Cao Ba Loi (2016) in Tien Giang on correlation of vector index and SXHD. Number of mosquitoes Ae. aegypti caught in an outbreak with the number of dengue patients in outbreaks had no correlation between Ae mosquito. aegypti with outbreaks of SXHD. This shows that epidemic prevention such as insecticide spraying, mosquito and larvae removal campaign when deployed may not immediately reduce the number of dengue cases but will help control the vector and reduce transmission in the next time [
