Since June 13, it is free to travel again within Sweden. But according to Professor Fredrik Elgh, the risk of being infected is still high and you should therefore keep your distance. This is especially true when traveling - on buses, trains and flights.

- Sitting next to, just behind or in front of each other you are too close. If anyone is infected then the whole train coupe or bus is at risk of being infected, he says.

Keeping distances on buses and trains is not always the easiest, however. Although the Public Health Agency encourages people to keep their distance to each other, many travel companies are placing the responsibility for this on the traveler.

SVT has talked to several tour operators, who all say that they have measures to reduce the risk of contagion among summer domestic travelers. These include, for example, more frequent cleaning routines, information for travelers before and during the trip more generous re-booking and cancellation procedures.

But few have changed their booking routines so that single travelers do not have to sit next to someone else and several companies have no booking stop, which means that their tours can be fully booked.

Oral protection reduces the spread of infection

In addition to sitting sparsely when traveling, you should also use mouth guards, believes Fredrik Elgh. He thus goes against the opinion of the Public Health Authority that there is not enough scientific support that oral protection would have a major effect on the spread of infection.

- It is completely wrong and there is scientific evidence for it, I would like to see the evidence to the contrary if the Public Health Authority should continue to have the hard-knuckled attitude, he says.
