On the other hand, when his removal is but temporary and the patient expects to return home after a few months, the amount of disinfection would be considerably modified. When he enters a sanatorium, his house must be fumigated and cleaned, so that for a few months at least the family may be relieved of danger. Under such circumstances, it would not be necessary to counsel the destruction of the mattress and bedding that he is to use upon his return. Meanwhile, no other member of the family should use these things, although in certain instances it is almost impossible to prevent their doing so. For such cases the municipal sterilizer is needed—indeed no community can make much headway against tuberculosis until it provides a means of removing the danger without causing loss to the individual. =Vacant Houses.= When a family’s removal leaves a vacant house, there is naturally no one left to do the cleaning. The Health Department will do the fumigation, but the more essential house-cleaning remains undone. These houses often stand idle for weeks or months before finding a new tenant. Even if it were possible to discover the landlord or owners (a task which in itself would require a staff of employees), it is doubtful whether they would clean these houses themselves, or notify their new tenants of the need for extra vigilance. Legislation compelling house-cleaning would be difficult to put through. The landlord feels relieved of all responsibility when once the fumigation is accomplished, and that this fumigation is not a hundred per cent. effective is no concern of his. He, together with the general public, has been misled as to its true value. Nor is thorough cleaning, painting, and papering an expense that he would willingly incur. The question of the fumigated but not necessarily safe house is one that causes considerable anxiety. We feel that the only way to deal with it, is that the nurse keep these vacant houses on her visiting list, so to speak, and watch for the time when they are re-let. This entails considerable loss of time, which she can ill afford to spare from her patients, but the information she can give the new tenant will have distinct preventive value. She must tell the newcomer that he has moved into a house in which there has been tuberculosis, and that only by the most exact and painstaking efforts can it be made safe.
