A scientific study has found out that mouthwash can kill coronavirus within 30 seconds of exposure.
Scientists at Cardiff University found out that over-the-counter mouthwashes having at least 0.07% cetylpyridinium chloride (CPC) indicated “promising signs” of reducing transmission of the virus. Their preliminary report supports a study published last week that found CPC-based mouthwashes helpful in reducing the viral load of persons infected with the virus. This study is yet to be peer-reviewed, which means that it has not yet been scrutinized by other scientists.
This report comes ahead of a clinical trial on patients at the University Hospital of Wales in Cardiff to find out if mouthwash can reduce coronavirus in a patient’s saliva. The results are expected to be published in early 2021. Prof. David Thomas told the PA news agency that although the study is very encouraging and is a positive step, more clinical research is needed. He also said that the reason for their ongoing clinical study is to find out if the effects of these over-the-counter mouthwashes on the corona virus achieved in the laboratory can work in patients. The ongoing study will also show the efficacy of a dose of the mouth wash in patients with Covid-19.
Dr Nick Claydon, a specialist periodontologist, said this study could lead to mouthwash becoming an important addition to fighting coronavirus together with hand washing, physical distancing and wearing masks, both now and in the future.
There are more than 54 million confirmed cases of COVID-19 globally and restrictions have been intensified up to control spiraling infections. Let’s continue to follow the preventive measures issued by the government, including washing hands frequently and maintaining social distance.
