All this talk about asymptomatic people carrying a virus without knowing it and infecting others brings to mind the story of … Mary Mallon.
No doubt the more astute medical types will recognize the name, but for the rest of us she was better known as Typhoid Mary.
TL,DR version: In the early 20th century a functionally illiterate Irish woman wound up being a carrier for typhoid fever. Mind you, she seemed pretty healthy and had no reason to think she was sick..but wherever she went and worked as a cook…people got sick and died.
Eventually, in some pioneering medical investigatory process, the NYC health people figured out that Mar was making other people sick. The record is a little unclear if they tried to explain it to her but it isn’t hard to imagine that someone with her lack of education might not grasp the idea of being a carrier. All she knew was that the one marketable skill she had was being taken away from her. So, she nodded her head, said she’d stop cooking, and went right on cooking for more families who mysteriously got sick.
Eventually the health department locked her up, quite against Mary’s will, and she wound up spending the rest of her life on North Brother Island.
If you’d like to read the more detailed version, and follow some of the legal wranglings that locked her up, try this and this.
In a time where many people chafe at the notion of .gov forcing restrictions upon them in the name of the ‘public health’ it’s interesting to see how far some municipalities went.
