I don't know if 'Everyone' knows how dangerous Chicken Pox can be, to Imuno-Suppressed people-it CAN be lethal! If not, as a lady who was asked to look after her Grandson, then please DO take considerable care.
I have a permanent arrangement, with my GP, to immediately prescribe Anti-Virals-as am emergency measure-should I ever find that I have had inadvertent contact.
Sorry to be so dramatic but, based on this lady's question, thought that a suitable comment/warning was in order.
On a lighter note, it's not long until Cr...Crist...you know!
Best wishes everyone
