[Construction and application of a staged early warning model for dengue fever].

Abstract

To achieve early warning of dengue fever from multiple sources and improve the ability to detect and identify dengue fever outbreaks timely, we took Hangzhou as an example and proposed the possibility of early warning of dengue fever. This study divided early warning of dengue fever into three stages: early warning of epidemic source, epidemic symptom, and epidemic. The early warning of epidemic source and epidemic symptom were emphasized to provide reference for other similar studies. Our findings showed that the staged warning of dengue fever was meaningful. Combining the source early warning with the symptom early warning could improve the sensitivity of the warning. Monthly warning can be used as a supplement to weekly warning.
