Detailed description

The acute pneumonia pandemic caused by a new strain of corona virus 2019 named as COVID-19 by the World Health Organization (WHO) is a pandemic caused by SARS-CoV-2 virus. The reported symptoms have included, but are not limited to fever or chills, cough, shortness of breath, muscle aches, headaches, loss of taste or smell, diarrhea, dizziness, sore throat, abdominal pain, anorexia, and vomiting. The hard capsule KOVIR is a product based on the traditional prescription named Nhân sâm bài độc táng which is used to treat the cold conditions, also known as the initial plague according to the theory of traditional medicine. The study timeline is expected about 7 months, including enrolment period, 14 days of treatment, data entry and analysis. The study compares between standard dose regimen of KOVIR combined with background treatment in COVID-19 patients and placebo combined with background treatment in COVID-19 patients. All participants will be treated and followed up in 14-day period. In case the participant meets the discharge criteria before 14 days, discontinuing the study drug will be done at the discretion of the investigators. Screening procedures occur at Day 1. Periodic assessments are conducted daily from Day 2-14. Finally, End of study visit is conducted.
