My late father in law had TB , or as he preferred to call it, a 'spot on his lung' ,when lordalex was a youngster. His abiding memory is of going with his Dad to the chemist to pick up his prescription and his Dad asking for it in a different flavour 'this time', only to discover when he got the powder home that every one tasted as foul as every other one. He soldiered on, though, and made a complete recovery. This must have been in the late fifties/early sixties. He didn't have any time off work, though his colleagues were not all that keen to get close to him.
I can also remember my own parents talking about what TB was like in the 1920s and 30s . They said it wiped out whole families of children in their teens, one after the other.
My mother's brother died of it and one of her sisters only just survived by living long enough for the appropriate drugs to become available. Dreadful days.
Here's hoping that the resistant strains do not take hold.
