A Randomized Controlled Clinical Trial on the Use of Saline Nasal Irrigations to Eradicate Localized Nasal Infection by SARS-CoV-2

At the moment of diagnosis, patients were asked to fill out an ad hoc questionnaire to subjectively evaluate symptoms and comorbidities at the moment of diagnosis and of negativization. Subjects performed a daily nasal swab. When the subjects tested negative for the first time, they had to complete the questionnaire once again. Patients were given nasal washes (Tonimer Panthexyl®) to be performed three times a day, and in any case after nasal swab.
