The _organization of health services_ to combat unexpected epidemics would be of great assistance. In times of peace, prepare for war. In all but the largest cities the health authorities are generally so free from contact with epidemics and are so pressed with routine that they do not organize in readiness for an epidemic which may not come. There should be a closer co-operative organization between health officials and practising physicians, so that the latter may aid to a greater extent in the public health work. The physician co-operates in furnishing information required by the health officer, but too frequently takes little interest in what further is done with this information. The medical profession should be made to understand the importance of public health work, should have a general comprehension of the methods used in its execution and should particularly develop a sympathetic and co-operative mental attitude. The medical societies of the country should be so organized that at a moment’s notice their membership can be mobilized for the defense of the community. There is much that the practising physician does not know about influenza. One of the leading internists in one of our largest cities, during the 1920 epidemic, refused to call his cases influenza and treated them as mild “grip.” It is stated that he lost an unusually large number of his patients. There are still many who believe that the two diseases are not identical. Not only is this detrimental to the patient, but as it results in failure to isolate the sick, it is detrimental to the community. Nursing groups should be organized to aid at a moment’s notice. Much work has been done and great experience gained by both the physicians and the nursing organizations during the last epidemic. Now is the time to prepare for the next epidemic or pandemic. With the remembrance of 1918 fresh in our minds we can establish a working system, while if we delay until the expected arrival of another epidemic much of our painfully acquired knowledge will have been forgotten. Opinion differs as to whether influenza should be made a _reportable disease_. The added expense would be not insignificant. This particular malady presents the additional complication of being difficult of diagnosis. The records would at best be inaccurate. The author believes that certain experiments in reporting the disease even in interepidemic times should be carried out. This should be done by competent epidemiologists who could later formulate plans for the permanent reporting of the disease. We will discuss this further under the heading, “Constructive Research.”
