Very interesting. Maybe some of those tb sanitariums which were located in the mountains did some good. I think the patients used to sit on the porches. Were the porches on the south side of the building?

They would use large sunny rooms appropriately named solariums. They used leaded glass in the windows because regular soda glass sucked up the UV rays.

TB isn't a virus, if I remember correctly.

However, my grandfather worked for a while at such a sanitarium as you mention, and yes, the patients there did get more sunlight than they otherwise would have.
