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.
为实现登革热多源预警，提高及时发现和识别登革热疫情暴发的能力，本研究以杭州市为例，提出登革热分阶段预警的可能，将登革热预警划分为疫源预警、疫兆预警、疫情预警三个阶段，并着重介绍疫源预警、疫兆预警两个阶段，以期为其他类似的研究提供参考。研究结果显示，登革热的分阶段预警是有意义的，将疫源预警与疫兆预警并联能提高预警灵敏度，月预警可以作为周预警的补充。.
