Using Xylitol Nasal Spray to Reduce SARS-CoV-2 Infections

This study investigates the use of xylitol nasal spray on symptomatic and asymptomatic patients, who were high-risk healthcare workers at hospitals in India during the Delta variant phase of the pandemic. The results significantly reduced SARS-CoV-2 infections by 62%. This multicenter-double blinded randomized controlled trial demonstrated the xylitol nasal spray was well tolerated with good user acceptability and a benign safety profile.
