Epidemics
How doctors redefined influenza after 1889
Open access · cc by · source: Europe PMC
Bresalier argues that post-1889 influenza was a new disease identity, aligned across field, clinic, and lab around a germ that later proved the wrong microbe.
Key findings
Greenwood’s ‘modern period’ began with 1889–94 pandemics. Isolation was a dream during huge attack rates. Clinicians found nervous and respiratory pictures, not old catarrhal textbook influenza. By the 1900s a bacillus was necessary but not sufficient. The 1918 pandemic was approached with this 1890s–1900s toolkit, even though the agent was later identified as a virus.
Methodology
The article reconstructs Local Government Board reports, clinical textbooks versus 1890s bedside notes, and work on Pfeiffer’s Bacillus influenzae, showing how LGB investigations stitched epidemiology, clinical description, and bacteriology into a specific infectious disease.
Limitations
This is a history of disease identity, not a virology paper. It does not re-type 1890 samples. Retrospective ‘wrong microbe’ judgements are the foil, not the method.
