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. UNITED STATES. EXTRA-CANTONMENT ZONES-CASES REPORTED WEEK ENDED FEB. 22. DISEASE CONDITIONS AMONG TROOPS IN THE UNITED STATES. The following data are taken from telegraphic reports received in the office of the Surgeon General of the United States Army for the week ended February 14, 1919. Reports from the American Expeditionary Forces are delayed in transmission, and the "current week" for troops in the American Expeditionary Forces is not the same period as "current week" for troops in the United States. 1 Sick and death rates among troops in the United States will continue to be relatively high as the numerical strength of troops in the United States continues to decline from week to week as a result of demobilization. Well men only are eligible for discharge, while the sick and otherwise disabled are retained in service for further treatment. The continued influx of sick and wounded (properly chargeable to commands overseas) is another factor tending to increase rates in the United States and to diminish correspondingly similar rates overseas. 1 |
