Summary Contemporary medical reports from Britain and Germany on patients suffering from a pandemic infection between 1889 and 1891, which was historically referred to as the Russian flu, share a number of characteristics with COVID‐19. Most notable are aspects of multisystem affections comprising respiratory, gastrointestinal and neurological symptoms including loss of taste and smell perception; a protracted recovery resembling long covid and pathology observations of thrombosis in multiple organs, inflammation and rheumatic affections. As in COVID‐19 and unlike in influenza, mortality was seen in elderly subjects while children were only weakly affected. Contemporary reports noted trans‐species infection between pet animals or horses and humans, which would concur with a cross‐infection by a broad host range bovine coronavirus dated by molecular clock arguments to an about 1890 cross‐species infection event. Contemporary clinical reports on patients of the Russian flu pandemic of 1889 to 1891 show striking similarity to COVID‐19 patients, demonstrating *multiorgan affections of the respiratory, intestinal and neural system, *loss of smell and taste, *and long disease symptom duration.
