Should Arsenal even be travelling to Austria?

Are Arsenal endangering themselves by traveling to Austria?

The Sun has reported that a Rapid Vienna player has recently tested positive for coronavirus and although the player who is unnamed is isolating at home. we are still expected to travel to play as there is no risk posed to anyone else.

Although it has been revealed that “Routine tests uncovered a single case of coronavirus with additional checks set to take place ahead of Thursday’s game.” what I fail to understand is that if the player has already tested positive, it won’t take two days to get out of his system will it! And so, Arsenal are still expected to travel to Austria and are still expected to take part in the game even though he has more than likely come into close contact with his teammates.
