Mouthwash could protect against coronavirus, scientists claim
A group of scientists is calling for urgent research into whether readily available mouthwash could be effective in reducing the spread of coronavirus.
They conducted a review of the scientific research in the area to assess whether mouthwash could have the potential to reduce transmission in the early stages of Covid-19 infection.
SARS-CoV-2 is an enveloped virus with an outer fatty (lipid) membrane.
However, according to the researchers, so far there has been no discussion about the potential role of damaging this membrane as a possible way to inactivate the virus in the throat.
They say previous studies have shown that agents commonly found in mouthwashes – such as low amounts of ethanol, povidone-iodine and cetylpyridinium – could disrupt the lipid membranes of several enveloped viruses.
However, they stress that it is not yet known whether this could also be the case for this new coronavirus, and people should continue to follow Government guidance.
