One worker at Bath shipyards infected 356 others, so there is some reason to be concerned.
That being said, tuberculosis is not always contagious. You have stated facts which may not be facts.
The best answer would be to contact your local department of public health and the hospital where this woman is being treated.
Generally, if there is exposure they want to know, and will provide free testing.
Does anyone know anything about it?
P.S.- I don't have any symptoms, but right now is probably too early to determine whether I may be infected using symptoms.... It has only been two days since I last saw her.
