Since the outbreak of corona virus disease-2019 (COVID-19), the timely intervention of Chinese medicine has played an important role， it can significantly improve the clinical symptoms of patients, alleviate fever, cough, shorten the course of disease and reduce the conversion rate of mild disease to severe disease， moreover, it has obvious advantages in improving survival rate, prognosis and quality of life in patients. In order to make better use of the therapeutic effect of Chinese medicine and overcome the epidemic situation as soon as possible, various provinces, municipalities and autonomous regions have introduced local Chinese medicine treatment schemes in accordance with the geography, climate and epidemic situation. In this article, we have analyzed the similarities and differences among treatment schemes from the perspective of three factors, and it is believed that the onset season is the same for this disease, and the differences between treatment schemes mainly depend on geographical and climatic factors. The results showed that in seven regions of China, the early symptoms in warm and humid regions such as Central China, South China, East China and Southwest China were characterized by "wet, warm, hot, and toxic", and treatment schemes mainly adopted the recipes with clearing heat and detoxifying, strengthening spleen and removing dampness functions. The early symptoms in cold regions such as Northeast China, North China, and Northwest China were mostly characterized by "cold, wet, wind, and toxic", and the therapeutic recipes emphasized on the effects of expelling wind and cold, removing toxicity and dampness. Among them, the national plan with the Hubei epidemic situation as an important reference has gradually evolved from a single syndrome attribute of each period to both cold and hot syndromes with multiple treatment methods. With the development of the disease, epidemic toxin and toxic heat in the lungs are the main characteristics in the medium term, when the treatment mainly focuses on purging heat and removing toxins. In severe cases and advanced stage, internal block and outward desertion are the main symptoms, when the treatment mainly focuses on block dredging and relieving desertion. In the recovery period, deficiency of lung and spleen Qi, and deficiency of Qi and Yin are the main symptoms, when the treatment is mainly used to invigorate the spleen, tonify the lungs, and nourish Qi and Yin. The physical factors are mostly reflected in the prevention program, so they are rarely mentioned in the treatment program. The Chinese medicine treatment schemes of COVID-19 in different regions show obvious differences. It is of great significance to analyze these differences and sum up the corresponding laws for the differential prevention and treatment of infectious diseases like COVID-19.
