Rsv recovery time and groups

My little girl started coughing Thursday of the school holidays, she is now free from symptoms. And it's now 10 days (1.5weeks) since the symptoms started. Would she be okay to start baby groups again this week, or would you wait another week? I'm not wanting to spread RSV but of course the groups are paid for so don't want to miss more than I have to. What would you do?
