TYPHOID MORBIDITY REPORTS.

PRACTICE IN MINNESOTA IN CASES EXTRA-STATE IN ORIGIN.

The Minnesota State Department of Health is making a practice, where possible, of determining, in reported cases of typhoid fever, whether the infection was received in Minnesota or elsewhere. The cases receiving infection from outside the State are being reported by the Minnesota authorities to the health authorities of the States in which the infection was received.

In the control of typhoid fever cooperation of this kind is desir able, and the practice of the Minnesota authorities is highly commendable. In time the notification of extra-State cases in this way will undoubtedly become general.

PREVALENCE OF DISEASE.

No health department, State or local, can effectively prevent or control disease without knowledge of when, where, and under what conditions cases are occurring.
