According to the study, which examined Chinese train passengers, it depends, among other things, on how close you are to an infected person, but also on how long.
The risk of becoming infected increased by an average of 0.15 per cent every hour. Travelers traveled together, and for those sitting in an adjacent seat, the risk increased by 1.3 per cent during the same period.
How much difference does it make to travel by train for four hours and sit on a bus for 30 minutes?
- Time matters, four hours is eight times longer so it matters. Then it also matters how close you sit, in a train you may be able to sit further away and then it is a factor that reduces the risk of becoming infected, says Magnus Gisslen, professor and chief physician at Sahlgrenska Hospital.
