For parents who are concerned about their children catching RSV in a crowded place like the mall, a virtual visit with Santa may be the answer. Some websites have a professional Santa available to speak with your child via video chat (i.e. Zoom, Facetime, Skype) for a fee. Some even permit family and friends to join the meeting. Here are a few such sites:
