1. Introduction
In traditional Chinese medicine (TCM) novel coronavirus disease 2019
(COVID-19) belongs to the category of “epidemic diseases”. The cause
of the disease is “plague rage” with characteristics that include
rapid onset, mutual infection, similar symptoms, and serious illness.
The COVID-19 medical scheme (trial edition 8) (National,et
al.,2020)suggests that different considerations such as the state of the
illness, underlying physical conditions, and local climate
characteristics impact the clinical manifestations and potential
treatment of COVID-19. Current TCM understanding of the disease suggests
that it primarily affects the lung, and its etiology and disease onset
and progression are mainly due to the cold-dampness epidemic pathogen.
Traditional Chinese medicine symptoms and protocols vary for COVID-19,
which is a reflection of the complexity of the disease. The main cluster
of COVID-19 patients in Chongqing, China was located in Wanzhou. Thus,
this study conducted a retrospective
analysis of patients with COVID-19 from Wanzhou to summarize their TCM
symptom characteristics and prescriptions. These findings will provide a
reference for the regional pathogenic characteristics of COVID-19 and
TCM treatment based on symptom differentiation.
