Brief Summary
Chinese medicine has been used for thousands of years in the treatment of epidemic diseases. Through the long-term struggle with the epidemic, Investigators have accumulated and explored a lot of prevention and control experience. According to recent reports, Chinese medicine plays an important role in the treatment of COVID-19. For example. Therefore, it is of great clinical significance to further develop the prevention of COVID-19 by Chinese medicine. According to the 《Diagnosis and treatment of COVID-19》published by National Health Committee and the experience of professional TCM physician, although the disease is generally susceptible, individuals with the body constitution of "deficiency of Qi and Yang" and "deficiency of Qi and Yin" are more prefer to suffer from COVID-19. Therefore, "Invigorating Qi and Yang, invigorating qi and Yin" can be regarded as the primary strategy of preventing COVID-19. Therefore, "Invigorating Qi and Yang, invigorating qi and Yin" can be regarded as the primary strategy of preventing COVID-19 in Chinese medicine. After a series of questionnaire surveys and blood sample collection, investigators can estimate subjects with body constitution is more likely to infect COVID-19.

Potential COVID-19 susceptible body constitutions will be measured by the scale of "Self-test for classification and judgment of body constitution by traditional Chinese medicine (TCM) theory"
At the beginning of the clinical trial, the classification of body constitution will be determined by scale of "Self-test for classification and judgment of body constitution by Traditional Chinese Medicine (TCM) theory", in which 8 kinds of body constitutions are involved, including the potential COVID-19 susceptible body constitution "deficiency of Qi with either Yang and Yin". There are 9 types of body constitution and 7 choices for each body constitution. The minimun and maximum score for each body constitution is 7 and 35, respectively. The total score of this scale is 315. Higer score in a specific item stands for the stonger correlation with a specific body constitution.

Changes of TCM-based syndromes will be measured by the "Questionnaire of TCM symptom"
The scale of "Questionnaire of Traditional Chinese Medicine (TCM) symptom" will be used to measure the changes of TCM specific symtom before and after the treatment, such as the changes of "Irritable motion" and " insomnia". The scale of "Questionnaire of TCM symptom" consists of 20 items and each item has 4 choices. The minimun and maximum score for each body is 1 and 4, respectively. The total score of this scale is 80. Higer score in a specific item represents the stonger correlation with a specific TCM symptom

Potential changes of fatigue status will be measured by Fatigue Scale
The fatigue scale is a 13-item scale of fatigue status. Items are scored on a 0 to 4 response scale with anchors ranging from "Not at all" to "Very much so". To score the fatigue, all items are summed to create a single fatigue score ranging from 0 to 52. Higer score stands for a stonger correlation with fatigue.
