Mouthwash has the potential to protect against COVID-19 infection by killing the coronavirus before it can infect human cells, according to a new report.

Coronaviruses belong to the class of ‘enveloped viruses’, meaning they are covered by a fatty layer that is vulnerable to certain chemicals.
A team of international researchers says mouthwash could destroy the outermost layer or ‘envelope’ of the virus, preventing its replication in the mouth and throat.
Scientists say there is a need to test the effectiveness of mouthwash in trials, although there is currently no clinical evidence that it would be successful.

The World Health Organisation has already said: ‘There is no evidence that using mouthwash will protect you from infection with the new coronavirus.’

The study authors do not say that current commercially mouthwash prevents COVID-19, but that further research into mouthwash chemicals could be beneficial.
