Evaluation of Number of Particles Containing Viral RNA and Their Virus Infectivity in Exhaled Air From Participants With Upper Respiratory Tract Infection Symptoms, Before and After Use of One Dose With ColdZyme Mouth Spray
Many respiratory diseases spread through aerosols. ColdZyme is a mouth spray that protects against upper respiratory tract viruses causing common cold and flu-like symptoms. ColdZyme forms a protective moisturizing barrier on the mucous membrane of the oral cavity and throat. The objective of this study is assessing if ColdZyme could also contribute to decreased airborne transmission by decreasing the amount of (infectious) virus that is exhaled by an infected subject.
