Marie Ciasullo, Fairfield County, Connecticut
She and her 3 kids all have Lyme and QUOTE:
Number of family members with LD: 4 immediate, 16 extended
My parents both have Lyme; two of my sisters have Lyme; one brother, one sister-in-law and one brother-in-law also have Lyme. Oh, and five nieces and nephews. We have all been diagnosed at different places, in different labs. This is so strange and so scary and oh-so sad.
