Good news. Hopefully he will start AO. Not perfect with a 5 sets in the hated heat coming back from severe sickness but maybe he can bribe the organizers to give him evening sessions.
No I'm not but a sportsman should have a much better fitness than me...if It took me 15 days to go back to work a sportsman should recover within 1 or 2 months so I guess it's not mono who stops Robin to go back to tennis but his wirst problem. He hasn't played since Bastad, mono is far behind him now, believe me or maybe it's another illness which bothers him ?? I can swear than my body is not stronger than Robin's one so mono should be nothing serious for him. It's really strange that he vanished in the air after Bastad, hope he has no personnal problems
An elite athelete doesn't have a stronger immune system than a non-athelete. In fact it's often weaker. It's even more visible in pure endurance sports but a tennis pro practices a lot too and that makes them vulnerable.
You could argue that from injury they will recover faster. But from sickness they will often recover slower. Fitness doesn't help really. Or do you think you battle mono with stamina and muscles? Then us normal people would have it for a year and Robin would be back in a week.
In fact many people get so weak symptoms from mono that they never even knew they had it. Others are in bed for weeks. Impossible to say something like 2 weeks, 4 weeks, 6 weeks, 2 months. Every case is individual.
