Since fumigation is only a matter of six hours’ duration, it will cause no great hardship or inconvenience to the family which for this short period must be turned out of the house. Yet many people complain bitterly over this trial, and raise every possible objection. They are willing enough to have one room done, but refuse to allow more. The nurse must explain that a six hours’ inconvenience is better than risking health and life, and she should also explain that in insisting upon fumigation the Health Department is neither arbitrary nor vindictive. Fumigation is a rather costly affair, and this expense is incurred, not to annoy but to protect the community. In winning over a reluctant family she has a chance to do excellent educational work. It is always better to secure their intelligent co-operation, even though it take long and patient argument, than to end the discussion by abruptly informing them that fumigation is compulsory, and will be done whether desired or not. =House-Cleaning.= Fumigation must always be followed by most searching and thorough house-cleaning, which important task must be done by the family itself. All floors should be scrubbed with hot water containing lye or soda solution and all washable surfaces should be likewise treated. This includes furniture, doors, door knobs, windows, stairs, banister rails, and so forth. The necessity for this house-cleaning cannot be too strongly emphasized. =Burning and Sterilizing.= The most highly infective material is the bedding, mattress, pillows, clothing, and so forth, which have been used by the patient. Since these articles cannot be made safe by formaldehyde fumigation, and since most of them cannot be washed and boiled, there are but two methods of disposal. The most drastic and wasteful is to burn them, yet this must always be advised unless we can offer the alternative of sterilization under high pressure steam. To burn infective material involves a loss which few people can afford, and they are loth to make the sacrifice; most of these articles, while laden with germs, are nevertheless serviceable and in good condition. To expect that they will be burned, therefore, is to expect the impossible. If the family consent to destroy certain articles, they reserve others, equally unsafe for use. The only alternative is the municipal sterilizer, and any community which expects to do effective preventive work must establish this as a factor of first importance.
