My wife is 29 years old and has never had the Chicken Pox. When she was younger, she received two Chicken Pox vaccines, and has never had an outbreak. We are supposed to be seeing a friend from out of town and her 3 daughters, but one of them has just contracted Chicken Pox. The other 2 are not showing symptoms yet.
Can you give us an idea about how much of a risk it would be for my wife to be around our friend and her 2 other daughters (not the one with Chicken Pox)? There is a chance that my wife might be in a very early stage of pregnancy, so we are trying to assess risk factors and how likely it would be for my wife to catch the Chicken Pox at this point. We aren't completely sure how the virus would be transmitted between carriers, etc. Any insight would be greatly appreciated!
