Effectiveness of Dengue Fever Prevention and Control Model Through Village Health Volunteer Participation in Border Area Context Ban Tha Ton Health Promotion Hospital, Mae Ai District, Chiang Mai Province

Abstract

     This study employed a mixed methods research approach with the objectives of developing and examining the effectiveness of a dengue fever prevention and control model through the participation of village health volunteers in a border area context at Ban Tha Ton Sub-district Health Promoting Hospital. Data were collected through workshops and interviews with 11 public health network leaders in Tha Ton Sub-district. Knowledge and skills questionnaires on dengue fever prevention and control were analyzed from 130 village health volunteers. The Breteau Index and dengue fever morbidity rates were compared before and after implementation of the developed model, using descriptive statistics, Wilcoxon signed rank test, and Paired t-test for data analysis.

     The study findings revealed that the developed dengue fever prevention and control model consisted of four activities: 1) community surveillance, 2) planning and knowledge-skills development, 3) dengue fever combat operations, and 4) summary and evaluation. The effectiveness study results showed that after implementing the developed model, the mean knowledge and skills scores increased with statistical significance at P<0.01 level. The Breteau Index decreased with statistical significance at P<0.05 level, and the dengue fever morbidity rate per 100,000 population decreased.
