Mouthwash can probably protect against coronavirus, scientists say

A group of scientists calls for an urgent study of whether a liquid for mouth rinses to be effective in reducing the spread of coronavirus.

They reviewed scientific papers, to evaluate whether a liquid mouth rinse to reduce the transmission of the disease in the early stages.

SARS-CoV-2 is enveloped virus with a lipid membrane. However, according to the researchers, while there was no discussion of the possible role of damage to this membrane as a possible way to deactivate the virus in the throat.

They argue that previous studies have demonstrated that substances which can usually be found in liquids for mouth rinsing, such as ethanol, povidone-iodine and CPC-free, can damage lipid membranes of several enveloped viruses.

However, scientists emphasize that it is unknown whether the same to be true in the case of the novel coronavirus, and people should adhere to the instructions of the government.

Scientists have estimated the current formulations mouthwash on their potential ability to affect the lipid shell of the SARS-CoV-2 and stated that some people deserve clinical evaluation.

Publishing their study in the journal Function, the authors wrote: “We emphasize that the already published research of other enveloped viruses, including coronaviruses, directly supports the need for further research whether the mouth rinse be considered as a potential way of reducing transmission of SARS-CoV-2”.

They said that the study aimed at the potential of this approach may include evaluation of existing or specially created formula of mouthwash in the laboratory and then in clinical trials.

Leading Deut studies Professor Valerie Odonnell, one of the Directors of the Systems Immunity Research Institute at Cardiff University, said: “the Safe use of the mouthwash as you normally would to rinse, has not yet been considered by physicians. In experiments and limited clinical studies revealed that some mouthwash contain enough is known to kill viruses ingredients to effectively cope with the lipids in a similar envelope viruses. What we don’t know yet is whether existing mouthwash against lipid membrane of SARS-CoV-2. Our literature review suggests that research is needed to establish its potential use against a new virus. This unexplored region and we hope that will be quickly generated research projects to evaluate it”.
