In Baltimore, nearly fifty per cent. of the patients under supervision are able to work. They seek a livelihood in office, factory, shop, hotel, and private home. We also find that nineteen per cent. of the families under supervision carry on some sort of gainful occupation within the confines of their own homes. As a rule, the patients who conduct these little home industries or occupations are more advanced cases than those able to find employment in shops and factories. In some instances, this home industry was carried on before the patient became ill; in others, by far the greater number, it is the direct result of an illness which has modified his earning power and compelled him to eke out a scanty income by this means. In many cases the actual work is not done by the patient himself but by some other member of the household. Sometimes these industries are not dangerous to other people, or the risk is so slight as to be negligible. At other times, the menace is grave. Each case must be considered upon its individual merits—one must not generalize and condemn in wholesale fashion. =Sewing and Sweatshop Work.= A number of our patients are dressmakers, or do factory sewing at home. Much has been written about the danger of clothing made under such conditions, either by the patient himself or by other members of his family. This output is not as dangerous as many people suppose, although such an admission would deprive the campaign of much picturesque photography. Much of this clothing is of washable material, such as cotton shirts, blouses, overalls, and the like, therefore any germs they might carry would be removed in the first washing. The danger has also been exaggerated in the case of woollen materials, such as coats, trousers, etc. Any organisms contained in these articles would soon die, or their virulence become so attenuated that little harm would result. This also applies to artificial flowers. It is not the occasional dose of bacilli, conveyed in this or any other manner, but the large and repeated implantations which do the damage. Infected clothing doubtless plays considerable part in the spread of the acute contagious diseases, such as measles, diphtheria, and scarlet fever, but in tuberculosis the risk is so slight that it may almost be called non-existent. Under such conditions, the danger is not to the wearers, or probable buyers, but to workers who make this clothing while in contact with the consumptive himself.
