Welcome to the Board of Health Care Magic,Chicken pox
is usually a disease of about three weeks. One week has gone before the blisters appeared. Probably two weeks are still there to complete the coarse of the disease.Till the scabs are there and they are wet you are contagious, so dear at least two weeks are more there for your isolation.
Please do not be in hurry to expose yourself to others. for the sake of your friends.
Hope your query is answered
