The city of Pontianak as the center of West Kalimantan Province plays an important role in the spread of dengue disease, to the surrounding regencies/cities. Objectives: To analyze the sensitivity, specificity, positive predictive value and negative predictive value of the diagnostic tools used, namely; fever/heat, chills, headache, combination of fever and chills, combination of fever and headache, and combination of fever, chills and headache. Methods: The design in this study used an analytical observational design with a cross-sectional design. Results: The validity as measured by clinical symptoms was compared with the standard, namely a complete blood count, the results of clinical symptoms that had high sensitivity were obtained, namely a single clinical symptom of fever/heat, namely Se; 75.00%, Sp: 89.36%, PPV: 17.64% and NPV: 99.15%, while the combination symptoms that have the highest validity are fever/heat, headache, rash on the skin, and bleeding from the nose. and Guzi with the value of Se; 87.78%, Sp:92.96%, PPV: 41.18% and NPV: 99.18%. Develop an application. A simple diagnostic tool, a Wi-fi-based diagnostic tool that can be accessed with a cellphone and has succeeded in making a Flowchart of the Dengue Fever Suggestion: Combination of symptoms of fever, headache, skin rash, and bleeding from the nose and Guzi are typical symptoms found in the study area.
