The dengue virus, which is carried by Aedes mosquitoes, causes dengue hemorrhagic fever (DHF). In the midst of the COVID-19 epidemic, DHF has emerged as a problem for public health in several countries around the world. A cross-sectional study was used to conduct the research. The goal of the study was to investigate the association between population factors, water source factors, agricultural area factors, and DHF epidemics during the COVID-19 pandemic. Secondary data was acquired by the researcher from the Ministries of Public Health, the Interior, and Agriculture and Cooperatives. Six districts in Nonthaburi Province were studied. The study was carried out in November and December of 2022. The data in this study was analysed using frequency, percentage, mean, standard deviation, and correlation. The findings demonstrated that population numbers were significantly connected to DHF epidemics during the COVID-19 pandemic and in the same direction (r = 0.922).At a significance level of 0.05, irrigation water sources had a significant relationship with DHF epidemics, as well as a reverse relationship (r = -0.904). As a result, a strong DHF monitoring network built on relevant technology is required. Moreover, research should be performed to identify new techniques for DHF management and prevention, and local wisdom should always be considered.
