Factors associated with Dengue Hemorrhagic Fever Control in the Epidemic Areas at Chaiyaphum Province 2020

Abstract

A cross-sectional study was designed. The aim of the study was to determine factors associated with dengue hemorrhagic fever control in the epidemic areas at Chaiyaphum Province 2020. The populations of the study were 127 sub-district health promotion hospitals. Sixty-five samples were selected by using inclusion-exclusion criteria. Multiple logistic regression was used to analyze the data. The results found that the most action was preparing measures before the outbreak such as eliminated larvae mosquitoes. The least action was sprayer checking.  Operation 3-3-1 measures passed the criteria about 35.4%, Incidence rate of dengue hemorrhagic fever was higher than standard (89.2%). Larvae house index was higher than standard (56.9%). Factors that significantly associated with incidence rate of dengue hemorrhagic fever were eliminated larvae mosquitoes before the outbreak (OR_adj = 2.92, 95% CI = 2.01-4.23), sprayer checking (OR_adj = 0.13, 95% CI = 0.09-0.21), disease control training for team before the outbreak (OR_adj = 3.29, 95% CI = 2.21-4.91), broadcast or local communication at village level (OR_adj = 2.78, 95% CI = 1.99-3.87) and passing standard criteria of 3-3-1 measurement (OR_adj = 1.93, 95% CI = 1.333-2.78). Furthermore, factors associated with larvae mosquitoes house index were eliminated larvae mosquitoes before the outbreak (OR_adj = 0.11, 95% CI = 0.05-0.24), using thermal fogger machine to control outbreak (OR_adj = 3.99, 95% CI = 2.39-6.66), sprayer checking (OR_adj = 0.57, 95% CI = 0.39-0.82) and operating 3-3-1 measurement passed the criteria (OR_adj = 0.56, 95% CI = 0.39-0.79). Therefore, Chaiyaphum Province should implement to eliminate Aedes aegypti larvae mosquitoes before the outbreak, preparing fogger machines for ready use. Operating 3-3-1 measurement when had the outbreak of dengue hemorrhagic fever was recommended.
