 San Sebastian was one of earliest towns hit by the 1918 Influenza epidemic, dealing with a first wave outbreak in February of that year.Officials feared for the city's reputation and attempted to keep the disease's spread quiet, to no avail, and the outbreak soon spread throughout Spain.Various rationalist architectural works, typically white or light-coloured, were built in the 1920s and 1930s, such as La Equitativa, Nautico, and Easo.
