[The fight against "avoidable" diseases and the 1918-1919 influenza epidemic in Spain].

This study tries to examine a series of proposals for the prevention of "avoidable" diseases, which were presented in Parliament between 1914 and 1922. These proposals illustrate how Spanish physicians approached public prophylaxis against infectious diseases. The article also attempts to highlight how the 1918-1919 influenza pandemic may have affected the number and content of such proposals.
