question: My mother may have shingles (I am taking her to dr in 1 hour) however my son had planned to travel 12 hours with his 2 & 4 year old to visit my Mom ( she was diagnosed with sm cell lung cancer & just had her 1st chemo session 2 weeks ago). Is there a chance my grandchildren could get chicken pox (which neither has ever had) from being exposed to Mom if she indeed has shingles?
