The second time, the revised version was tested with 138 patients in the Songkhla province. step 4, the research evaluation and satisfaction acquired from October 2022 to November 2023. The results was as follows: 1) Control of the dengue according to the 3-3-1 measure in health area 12 was timely, with a rate of 67.19%.

User satisfaction with the application was very high in all features (Mean = 4.20 ± 1.06 SD). In conclusion, the Dengue Alert application was proved to be a valuable tool for accessible,  efficient disease control and monitoring control measure.
