Excerpt from Pollution of New York Harbor as a Menace to Health by the Dissemination of Intestinal Diseases Through the Agency of the Common House Fly: A ReportDr. Jackson's report demonstrates that the common ¿y is one of the most active agents in disseminating certain intestinal diseases.Bacteriological studies were made of ¿ies that had been feeding on human excreta and they were found to carry vast numbers of disease germs. It was further found that ¿ies were most abundant where the accumulations of ¿oating excreta were greatest. Namely, near sewer outlets, and that cases of intestinal diseases were most numerous in the sections adjacent to such sewer outlets. It is clearly established by these studies that the excessive prevalence of certain diseases coincides with the presence of accumulations Of infected human excreta and with the presence of aggregations of ¿ies as the active agents for transmitting the disease germs derived from the excreta.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
