[mosschops30]

hes only been going for 2 weeks so im not sure whether he can go or not, or if its contagious
He is ok in himself.
He goes for one hour whilst i swim

I wouldn't if you can help it. It is caused by a virus so is contagious. He may have a mild case but others there could be more vulnerable and get it much worse, even end up in hospital. Having said that the same virus might also only cause cold symptoms in others so people probably go about with it all the time.
