No, they didn't quarantine. But the one in west Texas allowed more than adult visitors. My grandfather recovered but while he was at the Sanatorium, near San Angelo IIRC, my mom visited her daddy when she was 6-7 years old. I grew up hearing stories of Pepaw in the TB Sanatorium. But I found a photo of mom with my grandparents when cleaning out the GP's house after their death. The 3 of them were in a hospital corridor, he was in a bathrobe and Mom and Grama appeared to be in "Sunday go-ta-meetin" clothes. When I asked mom about it she told me about those visits, how tough they were for her as a little girl, for the first time.
I lost my father from TB in 1938...I was not allowed to visit,he would come to the window and wave.....I still remember it,I was 5 1/2. I still test positive when given the TB tine test because I had been exposed but never got the disease.
