The study will enroll 700 participants to KOVIR group and 300 participant to Non-KOVIR group. 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.
