Abstract: 【Purpose/significance】In the era of big data,the Public Health Emergency (PHE) risk intelligence is a necessary support for
the PHE risk prevention and control.【Method/process】First,this paper gives the definitions of PHE.PHE risk and PHE risk intelli?
gence.Second,this article analyzes the PHE risk intelligence work in the big data environment.Finally,this paper proposes a model for
PHE risk intelligence work in the big data environment【. Result/conclusion】The PHE risk intelligence work in the big data environ-
ment is driven by big data,and oriented to the PHE prevention and control【. Innovation/limitation】This paper establishes a model for
PHE risk intelligence work in the big data environment,which can provide a theoretical basis and method guidance for PHE risk intelli-
gence work in the big data era.However.,since this article does not verify the theoretical model involved with actual cases.there are cer-tain limitations.
