Servants and employees sometimes give tuberculosis to their employers or to their fellow employees. A consumptive cook, for instance, could very easily infect a whole family. A consumptive chamber-maid or dining-room girl might likewise give the disease to those upon whom she waits. There is all the more danger from sources of this kind because the person who has the disease is apt to hide it. Employers should insist that servants and employees of every kind shall use the proper receptacles for expectorated matter when they cough and expectorate.
