OBJECTIVE: To describe the epidemiological and social impact of the flu pandemic of 1918-1919 in 41 municipalities of Boyacá, Colombia. METHODOLOGY: descriptive, analytical-empiric, historic study with an epidemiological focus. The volume and structure of the population is established and determines the mortality rates for the variables of time, person and place. RESULTS: The pandemic began in October 1918 in Bogotá and reached Boyacá by road. The three chronological waves found in the literature were not identified. We found a significant difference in the behavior of the flu pandemic in the department of Boyacá with that described in Europe and North America by the specialized literature.
