Disclosure　of　patients＇　travel　route　information　by　government　departments　has　been　an　effective　and　indispensable　pandemic　prevention　and　control　measure　during　the　COVID-19　pandemic.　However,　this　measure　may　make　patients　susceptible　to　cyber　violence　(CV).　We　selected　13　real　cases　that　occurred　in　China　during　the　COVID-19　pandemic　for　analysis.　We　identified　several　characteristics　that　commonly　appeared　due　to　route　information,　such　as　rumors　about　and　moral　condemnation　of　patients,　and　determined　that　patients　who　are　the　first　locally　confirmed　cases　of　a　particular　wave　of　the　pandemic　are　more　likely　to　be　the　victims　of　CV.　We　then　analyzed　and　compared　six　real　cases　using　data　mining　and　network　analysis　approaches.　We　found　that　disclosing　travel　route　information　increases　the　risk　of　exposing　patients　to　CV,　especially　those　who　violate　infection　prevention　regulations.　In　terms　of　disseminating　information,　we　found　that　mainstream　media　and　influential　we-media　play　an　essential　role.　Based　on　the　findings,　we　summarized　the　formation　mechanism　of　route　information　disclosure-caused　CV　and　proposed　three　practical　suggestions-namely,　promote　the　publicity　of　the　media　field　with　the　help　of　mainstream　media　and　influential　we-media,　optimize　the　route　information　collection　and　disclosure　system,　and　ease　public　anxiety　about　the　COVID-19　pandemic.　To　our　knowledge,　this　study　is　one　of　the　first　to　focus　on　CV　on　social　media　during　the　COVID-19　pandemic.　We　believe　that　our　findings　can　help　governments　better　carry　out　pandemic　prevention　and　control　measures　on　a　global　scale.
