Anders Tegnell on oral protection: "The knowledge base is extremely weak"

During Thursday's press conference, the Public Health Authority opened the use of oral protection and visor in the elderly care.

- Despite the meager scientific evidence, we see that you can consider adding mouth protection or visor as an extra measure. This is a trade-off that one has to make locally and according to the conditions one has, said Malin Garpe, the Public Health Authority's unit manager for health hygiene, at the press conference.

But there is still no clear recommendation. In Current Affairs, state epidemiologist Anders Tegnell answered the question of why Sweden's line differs from some other countries.

- The reason it looks so different is because the knowledge base is extremely weak. There is only one study in the world that has tried to look at this, says Tegnell.

- It fits badly with what we are trying to push in Sweden, that if you are ill you should stay at home and not go out on the town with a mouthguard on you.
