Influenza : An epidemiologic study

This study offers a meticulous look at the patterns of influenza epidemics from the late 19th century through the devastating 1918‑1920 pandemic. Drawing on a wealth of earlier reports and the author's own observations, it traces how each wave unfolded, how the disease spread among families, neighborhoods, and larger crowds, and what clues emerged about its origins. The author seeks to bridge the gap between past and present knowledge, showing that many features of the recent outbreak echo those recorded in the 1889‑93 crisis.

A centerpiece of the work is a detailed house‑to‑house census conducted in Boston during the winter of 1920, supported by local charities and hospitals. The data reveal striking differences in infection rates by age, sex, occupation, and even neighborhood density, while also highlighting the role of healthy carriers and social gatherings in driving transmission. By piecing together these patterns, the study aims to inform future public‑health strategies and deepen our understanding of how flu spreads in modern urban settings.
