OBJECTIVE:To explore the differences in Traditional Chinese Medicine(TCM)diagnosis and treatment rules for coronavirus disease 2019(COVID-19)between Northern and Southern China based on the real-world data from 982 COVID-19 ***:All consecutive cases of COVID-19 admitted to the TCM department of designated COVID-19 hospitals in eight provinces and cities were retrospectively *** were divided into a Northern and a Southern group according to the location of the admitting *** symptoms,syndrome elements,syndrome distribution and herbal treatments were *** core prescriptions were extracted using the multiscale backbone-based network comparison algorithm(msbNC).REsuLTS:The distribution of syndrome elements showed that dampness was common in Northern and Southern China,wind and heat were more often present in the South,while fire toxin and spleen deficiency were more often encountered in the *** distribution of syndromes showed that the South was dominated by heat dampness accumulating in the lung(55.69%),while the North was dominated by dampness-toxin stagnating in the lung(44.90%).The results of core prescription mining showed that dispelling dampness,dispersing wind,clearing heat and strengthening spleen were the common treatment methods in Northern and Southern *** mild cases,Jinyinhua(Flos Lonicerae)and Lianqiao(Fructus Forsythiae suspensae)were often used in the South to clear heat and relieve exterior symptoms,while Chaihu(Radix Bupleuri Chinensis)and Huangqin(Radix Scutellariae Baicalensis)were often used in the North to relieve muscles by expelling *** moderate cases,Chaihu(Radix Bupleuri Chinensis),Qinghao(Herba Artemisiae Annuae),and Shigao(Gypsum Fibrosum)were often used to clear heat of Tri-jiao Channel and stomach in the South,while Fuling(Poria),Chenpi(Pericarpium Citri Reticulatae),and Dangshen(Radix Codonopsis)were often used to invigorate spleen and remove dampness in the *** severe cases
