VIRUS, CAVITY
In the present study, all three groups experienced a decrease in Ct values over time, indicating a reduction in the VL. These results are in accordance with previous reports that gargling and rinsing with mouthwash as well as rinsing the nasal cavity are associated with a reduction in the SARS-CoV-2 VL [Considering that the highest VL can be found in the first week after symptom onset [This study has some limitations. The sample size was limited. Furthermore, Ct values are semi-quantitative and the RT-PCR evaluation only indicates the presence or absence of virus fragments. More precise results could be obtained if the evaluation measured the infective capacity of viable viruses after using the rinsing protocols. In the present study, we adopted the measure of infectivity as previously described by Jaafar et al. [
