Hope your DS is better soon

I am not meaning to hijac but am wondering about the contagousness of bronchiolitis.

A friend of mines DD got this on Sunday confirmed with Doctor on Monday but wants to meet up with me on Friday. She said its not contagious but I am thinking that it is and I dont want my DD to get it and for her to then pass it on to other children.

Cna anyone tell me the contagous period with this?? TIA
