hi sandy
in the land of the free- probably less than in Typhoid Marys time
she was a typhoid carrier thro colonisation of her gall bladder and could only work as a cook. I think she was confined to the now unoccupied Roosevelt Island off Manhattan. So he house was left derelict for inspection and the standard of her cleanliness was much to be deplored ( hence she infected and killed her employers children).
there is cine film of her being arrested second time - in real time! so much for police selling tip offs
and she lived to god knows when excreting typhoid all the time into Manhattan sound or wherever
I mentioned this in 1980 to some rather badly behaved americans ( the canadians would go in and forcibly treat TB whether the pt wanted it or not) and their liberal sentiments were outraged that any freedom not to be treated and to infect whomever must NOT be violated !
