– Every other day, I stare at people using mouthpieces at press conferences. And it’s pretty obvious that you have a lot of face when you rinse your mouth, says state epidemiologist Anders Tegnell.
The use of mouthwash has been frequently discussed during the eruption of the crown.
In early April, the World Health Organization debated whether to change its advice on the use of mouth rinses and then evaluate whether increased use of masks could be helpful.
In this country, FHI has been firm in its decision to discourage anyone other than a health professional from using mouthwash, despite disagreement with some.
Even with much more infected people, the Swedish health authorities also agree with the Norwegians.
– put yourself in your face
On the Science Radio show, played by Expressen, state epidemiologist Anders Tegnell justifies, among other things, his advice on the use of mouthwash because it is very unpleasant to use.
– It is quite obvious that they are tireless being there all the time, which probably means that you have more viruses on your fingers than at any other time. That’s one aspect of it all, says the state epidemiologist on the show.

Tegnell believes the mouthwash discussion is based on a fairly small and limited study from Hong Kong, and says it is the only scientific basis for effective use.
The study he is talking about is probably a report that Dagbladet mentioned in early April.
In an article published in the journal Nature Medicine on April 3, a group of researchers presented evidence that surgical mouthwashes can reduce the amount of virus-containing particles that a contaminant spreads to the environment.
The study concluded that mouthwash can prevent someone infected with the virus from infecting others. It does not mean that mouthwashes are effective in protecting yourself from infection.
– Uncertain effect
Benjamin Cowling, who led the study at the WHO Collaborative Center for Infectious Epidemiology, commented on the study to Reuters:
– My point of view is that a cotton cloth or mask can have an effect, but perhaps less than a properly used surgical mask.
The Hong Kong study was also not enough for FHI to give its advice on the use of mouthwash.
– The effect of using a homemade mouthwash is uncertain. It hardly hurts to use it, but the question is how much effect it has, said Mette Fagernes in the FHI department for preventing resistance and infection to Dagbladet.
FHI’s advice on surgical mouthwash has been justified in the same way that Tegnell does.
– Mouthwashes are unpleasant to use and, as a general rule, unqualified personnel who have mouthwashes frequently touch the mouthwash and the rest of the face. If you’ve been in contact with dirty surfaces, you can quickly get in contact with your eyes and mouth, thereby increasing your risk of disease, FHI wrote on its website on January 30.
