I would like to know the origin of these "chicken pox parties". I've been on the phone to my mother tonight and I asked her about it and she had never heard of them. Her response was that if a kid in the neighbourhood had chicken pox when I was a kid (30 something years ago) they were quarantined for the duration, not allowed any friends or anything. (She did say they stopped at declaring the house a plague house and burning it to the ground.)
She also said she certainly never heard about them in her childhood, the only difference then was as she put it “we were less selfish then – if one kid got it we all had to have it, TB, scarlet fever, mumps, measles…â€.
