Objective

2

To analyze the traditional Chinese medicine（TCM） syndromes of 46 patients with coronavirus disease-2019 (COVID-19) by cluster analysis method.

Method

2

The 46 COVID-19 patients with TCM symptoms

signs

tongue and pulse were analyzed by frequency analysis and clustering analysis

and the TCM syndrome types of COVID-19 patients were classified and summarized by combining clinical expertise

and the evolution law was analyzed by combining the median days of the syndrome collection.

Result

2

The major signs and symptoms of the 46 patients with COVID-19: fever (frequency of 39

accounted for 84.8%)

poor appetite (frequency of 44

95.7%)

fatigue (frequency of 42

91.3%)

wheezing breath (frequency of 35

76.1%)

dry mouth (frequency of 21

45.7%)

lung condition short (frequency of 20

43.5%)

defecate pond (frequency of 15

32.6%)

red tongue (frequency 30

accounting for 65.2%)

yellowish moss (frequency 27

accounting for 58.7%)

and slimy pulse (frequency 30

accounting for 62.5%). TCM syndromes were divided into seven types

i.e. dampness and heat syndrome (13 cases)

dampness and toxin syndrome (10 cases)

heat stasis syndrome (7 cases)

dampness and heat syndrome (5 cases)

cold dampness internal invasion syndrome (4 cases)

dampness poison blood stasis syndrome (2 cases).According to the time of onset

there were cold and dampness syndrome (median days 6.5 days)

dampness was heavier than heat syndrome (10 days)

dampness and heat syndrome (10 days)

dampness and heat syndrome (11.5 days)

heat stagnation of liver and gallbladder syndrome (13 days)

dampness and blood stasis syndrome (15 days)

and Yin injury syndrome (16 days).

Conclusion

2

Among the 46 cases of COVID -19

damp-heat syndrome was the most common

followed by heat stagnation of liver and gallbladder syndrome

Yin injury and gas consumption syndrome

cold and damp internal invasion syndrome

and dampness and blood stasis syndrome. The pathogenesis of the disease evolved into heat and poison

and later appeared to consume Qi Yin performance.
