COLD, COMPLICATIONS, FLU SYMPTOMS
The effect of treatment was assessed using log cards. Patients completed the influenza-like symptom scale (ISS) twice a day in the morning and evening, which was divided into four levels (0 asymptomatic, 1 mild, 2 moderate, and 3 severe) according to the different degrees of ISS. When the symptom was zero to one for 24 h, it was recorded as normal, and recording was stopped.Body temperature was measured four times in the morning, noon, afternoon, and evening of every day. If the subject’s body temperature dropped below 37.3 °C for 24 h, body temperature recording was stopped.During the visit, it was necessary to ask and record the daily use of the experimental drugs and the combined use of other drugs taken at the same time. In this study, other drugs with antiviral effects and traditional Chinese medicine preparations to treat cold, relieve cough or resolve phlegm, interferon, and glucocorticoids were prohibited. During the medication period, if other symptoms or the current flu symptoms were aggravated, the patient returned to the test unit for relevant tests. The researcher judged whether there are any complications and recorded them at that time.
