WHO responds to claims that mouthwash 'could protect against coronavirus'

The World Health Organization has said there is “no evidence” that gurgling mouthwash can protect you from coronavirus – despite claims by experts.

A report suggested that the fluid could damage the bug’s protective membrane and potentially destroy Covid-19 before infecting human cells.

And it prompted scientists to call for “immediate study” to learn more about the impact of mouthwash chemicals in the fight against the deadly virus.

But the WHO said, “There is no evidence that using mouthwash will protect you from infection with the new coronavirus.”

Researchers argue that more research needs to be done on whether mouthwash can destroy the “coat” of the virus, preventing it from multiplying in the mouth and throat.

Experts have not claimed that commercially available mouthwash can prevent coronavirus, but instead encouraged an investigation into the chemicals used.

No studies have yet been conducted to conclude its effects.

Lead author Professor O’Donnell, co-director of Cardiff University’s Systems Immunity Research Institute said, “In test-tube experiments and limited clinical studies, some mouthwashes contain enough known virucidal ingredients to effectively fight lipids in similar enveloped viruses.

“What we don’t know yet is whether existing mouthwashes are active against the lipid membrane of SARS-CoV-2.

“Our literature review suggests urgent research is needed to determine the potential for use against this new virus.”

The researchers also state that the chemicals, chlorhexidine, cetylpyridinium chloride, hydrogen peroxide, and povidone iodine have the potential to prevent infections.

WHO added, “Some brands of mouthwash can remove certain microbes in the saliva in your mouth for a few minutes

However, this does not mean that they protect you against 2019 nCoV infection.
