本文通过回顾总结中医学对传染性疾病的认识，特别是近代各医家治疗传染性疾病经验，发现多从温病入手，运用卫气营血、三焦和脏腑辨证体系指导临床。但单一卫气营血辨证和单一脏腑辨证在现代传染性疾病的应用存在局限性和不足之处，建议在诊治现代传染性疾病时采用温病经典的卫气营血辨证和脏腑辨证相结合，以卫气营血辨证为横向系辨病情轻重和病邪深浅，脏腑辨证为纵向系辨明确病位，建立起了卫气营血—脏腑立体的联合辨证体系方法会更加全面。新型冠状病毒肺炎是新近出现的传染性疾病，中医防治具有明显的“三因制宜”特点，针对广东地区的新冠肺炎，作者论述了将卫气营血—脏腑联合辨证体系方法运用到临床实践的理论依据，认为卫气营血—脏腑联合辨证体系是比较切中广东地区新型冠状病毒肺炎的中医病因和病机演变规律的，值得进一步深入总结和研究，以期多角度、多方位探索广东地区新冠肺炎的中医辨证方法，为临床提供诊治思路，也为广东地区临床防控疫情提供可参考的中医诊疗方案和科学依据。

This paper summarizes the understanding of infectious diseases in Traditional Chinese medicine (TCM), especially the experience of recent medical practitioners in treating infectious diseases, and finds that most of them start from warm diseases and use the pattern differentiation system of weifen, qifen, yingfen and xuefen, triple burner and visceral organs to guide clinical practice. However, there are limitations and shortcomings in the application of single pattern differentiation of weifen, qifen, yingfen and xuefen or visceral organs in modern infectious diseases. It is suggested that in the diagnosis and treatment of modern infectious diseases, the combination of the classical weifen, qifen, yingfen and xuefen pattern differentiation and the visceral organs pattern differentiation should be used, with the former one as the horizontal system to identify the severity of the disease and the depth of the disease, and the later one as the vertical system to identify the location of the disease, establishing a three-dimensional joint pattern differentiation system of weifen, qifen, yingfen and xuefen and visceral organs, which will be more comprehensive. COVID-19 is a newly emerged infectious disease, and the prevention and treatment of TCM has obvious characteristics of "three causes and three conditions", and for the new coronavirus pneumonia in Guangdong, the authors discussed the theoretical basis of applying the combined weifen, qifen, yingfen and xuefen pattern differentiation system to clinical practice. The combined system is more relevant to the TCM etiology and pathogenesis of COVID-19 in Guangdong, and is worthy of further in-depth summary and research, in order to explore the TCM identification method of the new coronavirus pneumonia in Guangdong from multiple perspectives and directions, to provide clinical diagnosis and treatment ideas, and to provide reference and scientific basis to TCM treatment plans and scientific basis for clinical prevention and control of the epidemic in Guangdong.
