During　the　major　epidemic,　especially　when　the　number　of　patients　increases　sharply　and　medical　resources　are　tight,　the　prevention　of　the　epidemic　and　the　effective　treatment　of　patients　are　extremely　important.　This　paper　comprehensively　studies　the　services　and　applications　of　＂AI+5G＂　technology　in　this　context　to　improve　the　efficiency　of　therapy　and　prophylaxis　and　further　expand　the　medical　service　space.　Based　on　problems　and　practical　applications,　the　role　and　characteristics　of　AI　expertise　and　5G　IT　in　the　anticipation　and　treatment　of　main　pandemics　are　analyzed　through　case　analysis　and　induction.　The　research　results　demonstrate　that　＂5G　plus　AI＂　has　great　significance　in　initial　discovery,　monitoring　and　early　warning,　diagnosis　assistance,　pathological　sharing　and　diagnosis　and　treatment　development.　The　combination　of　AI　technology　and　5G　network　technology　can　effectively　contribute　to　the　reduction　of　cross-infection　and　treatment　pressure,　and　effectively　contribute　to　the　improvement　of　treatment　efficiency.　©　2022　SPIE.
