Between these two peaks, the of mortality closely linked to the First World War. The lowest number of deaths falls in the week of the armistice sources used are official death statistics and the Albo d’oro, between Italy and Austria-Hungary (signed 4 November a roll of honour of the Italians fallen in the First World 1918). This suggests links between Spanish flu and WWI War. The new estimate of deaths from the flu is 410,000 that cannot be merely explained in terms of movement of for 1918, which should be raised to 466,000 when the people and contagion. numbers are taken up to 1920. Deaths from Spanish flu among the military were about 70,000. The time sequence Keywords: Spanish Flu, Italy, WWI. n INTRODUCTION the global reach of the epidemic, in fact focuses on the flu in the city of Bologna [6]. Even more taly was one of the European countries most recent is a work by Alfani and Melegaro which Iseverely affected by the Spanish flu [1]. places the Spanish flu in the more general context Nevertheless, the influenza pandemic of 1918-19 of pandemics as a whole [7]. Military historians, in Italy has not been the subject of many studies. however, have tended to look at the influenza of The first to address the topic was Giorgio Mortara 1918 in relation to war [8-10]. Some authors believe in 1925 in a volume about Italian health in the that the Spanish flu was a direct consequence of Great War [2]. After Mortara’s important work, the war and that the conflict represented the real we have to wait more than thirty years to see a incubator of the virus [11]. Influenza, in fact, was new contribution on the subject, a volume by born in military camps, where men and animals Giovanni Cavina which traces the history of the (livestock and pets) were in close proximity. influenza epidemic in Italy. Only in recent years Most authors claim a close connection between the question of the health of Italians during the the flu and the conflict, though the conflict was not war come back into the spotlight. Of course, here, necessarily the primary cause. The relationship the Spanish flu played a central role [3, 4]. between influenza and war should perhaps instead The only monograph dedicated to the Spanish flu be sought in the rapidity of the virus’ transmission in Italy is a book by Eugenia Tognotti published and its global spread. These aspects would have in 2002 [5]. More recently, Sabbatani and Fiorino been determined by the crowded conditions in published an article which, while starting with the trenches and in hospitals and, of course, by the long-distance displacements of large masses of soldiers and workers [12-21]. Some scholars, Corresponding author however, either downplay the association of Alessio Fornasin the war with the pandemic, or at least do not E-mail: [email protected] consider it to be obvious [22, 23]. According to Jay 98 A. Fornasin, et al. Winter, one of the most important demographers official death statistics broken down by cause of writing on the Great War, the link does not exist death.

Part of the information extracted from the Albo d’oro is shown in Figure 1. The figure summarizes the monthly distribution of deaths by distinguishing victims of the fighting, deaths from disease (but not in enemy hands) and imprisonment (for all the causes). The decision to divide the information into three categories, two related to the cause of death and Spanish flu in Italy 99 one to the context of death, is in line, as we shall see, with the purpose of this work.
