Masking Description
Face mask and saliva SARS-CoV-2 viral RNA loads are measured before and after water rinse and before and after mouthwash rinse (intervention). Order is randomized. Participant is not told which rinse they are using, though can likely differentiate by taste.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
0.075% Cetylpyridinium Chloride 		Crossover design where a series of viral load measurements are taken before and after water rinse (placebo) and repeated before and after CPC rinse (intervention). The order of the rinses were randomized after the 19th participant.
  • Drug: Mouthwash Product
    Commercially over-the-counter Colgate mouthwashes will be administered according to standard package instructions. Viral load will be measured prior to and after mouth rinse using serial face mask and saliva samples. Additionally viral load measured prior to and after water rinse using serial face mask and saliva samples. These serial measurements and both CPC and water rinses were conducted consecutively in one visit.

Detailed Description

The study will consist of a Control Phase to optimize procedures for measuring expelled/exhaled viral load, and a Evaluation phase comparing different commercially available mouthwashes. In the Control Phase. up to 20 COVID-19 patients will be asked to undergo a sequence of face mask sampling and saliva collections prior to and after an oral rinse with (i) water and (ii) a commercially-available cetylpyridinium chloride (CPC) mouthwash. Based on outcomes of the Control Phase, the study will proceed into the Evaluation Phase, which will randomize approximately 40 COVID-19 patients to receive 1 of 4 commercially available Colgate mouthwashes following standard package instructions. Face mask sampling and saliva will be collected prior to and after the mouth rinse to assess impact on SARS-CoV-2 viral load.
