Arm Intervention/treatment
Experimental: Povidone-iodine 0.5% antiseptic mouth rinse
Subjects will be asked to rinse/gargle one time with 10 mL of Povidone-iodine 0.5% antiseptic mouth rinse for 30 seconds.
Drug: Mouth rinse
Subjects will be asked to rinse/gargle one time with 10 mL of assigned mouth rinse for 30 seconds.

Placebo Comparator: Placebo
Subjects will be asked to rinse/gargle one time with 10 mL of placebo mouth rinse for 30 seconds.
Drug: Mouth rinse
Subjects will be asked to rinse/gargle one time with 10 mL of assigned mouth rinse for 30 seconds.

Primary Outcome Measures :
  1. Change in viral load in oral cavity [ Time Frame: 5 minutes, 30 minutes, 60 minutes after intervention ]
    The primary outcome is the change in amount of SARS-CoV-2 in the oral cavity before and after intervention.

Secondary Outcome Measures :
  1. Clinical status after using antiseptic mouth rinse for 7 days [ Time Frame: 7 days ]
    Subject's clinical status at day 7 and the number of COVID-19 symptoms, symptoms onset and the severity of symptoms will be collected throughout Phase 2 of the study.
