What does World Health Organization (WHO) say about mouthwash’s efficacy on Coronavirus?
WHO website clearly mentions that there is no evidence that using mouthwash will help prevent one self from the new Coronavirus.
Is there any research done to check the effectiveness of mouthwash against Coronavirus?
There is research done titled “Virucidal Efficacy of Different Oral Rinses Against Severe Acute Respiratory Syndrome Coronavirus 2” which was published on The Journal of Infectious Diseases on 29 July 2020.
The findings suggest that some mouthwash helps in reducing the viral load in the mouth during COVID19. This means the number of viruses in a COVID-19 patient’s mouth decreases by using mouthwash. While this does not cure the patient, but given that the new Coronavirus spreads when the virus is released while sneezing, coughing or talking, this has a potential to reduce transmission. The researchers of the study has recommended, ‘the evaluation of selected formulations in clinical context’. Further clinical research is being conducted in this aspect.
