From: Heterogeneity in regional notification patterns and its impact on aggregate national case notification data: the example of measles in Italy

Figure 2

Monthly measles case notifications for 1949–1996 standardised by regional mean. Regions are shown in customary geographic order, and data for each region are standardised by their mean. (NB as the city of Trieste was not incorporated into the region of Friuli Venezia Giulia until 1954, when the city's post-war status within Italy was finally resolved, two time series are shown for Friuli V. G.: up to 1954, and 1954 onwards)
