SARS Cov-2 Nasal Pharyngeal and Oral Pharyngeal Wash (SNOW) Trial SARS Cov-2 Nasal Pharyngeal and Oral Pharyngeal Wash (SNOW) Trial
Adults recently diagnosed with SARS-CoV-2 infection who use a 4-day combined intervention of nasal washes with 1% baby shampoo solution and oral gargles with Listerine Antiseptic® will have a reduced SARS-CoV-2 viral load compared to those using nasal and oral washes with normal saline. This combined intervention should be acceptable, tolerable and safe in this population. To test this, we are conducting a trial comparing the efficacy of a number of washes in reducing the oral and nasal SARS-CoV-2 viral load amongst adults.
At their home, participants will perform three nasal and oral rinses per day for 4 days and self-swab the nose and mouth before and after each morning rinse to collect specimens under the guidance of a zoom visit. On the morning of the 5th day participants will also self swab the nose and mouth for a final collection specimen. Participants will answer questions on an app and online platform.
