Average 9.9% of Italians have downloaded Immuni: here are the regions where the contact tracing app is most used and where it is not
About three months after its launch, it is time to make the first assessments on Immuni, the app chosen by the Italian government for the contact tracing of coronavirus. Immuni itself has made the calculations, publishing the map of the Italian regions with the percentage of users who have downloaded the app.
The data are updated to August 31 and between a region and another there are significant differences, but even in the most virtuous were few to download Immuni on their smartphones: the national average stops at about 9.9%. In general it is easy to see that in the South Immuni is used very little, in the Center a little more and only in the North the percentages are close to the minimum for the contact tracing to be effective. Or, at least, to the latest percentages declared by scholars, given that over time there have been very different communications. But where is Immuni used more and where less? Here are the data, region by region.
The map of Immuni
The Autonomous Province of Bolzano is the Italian territory most faithful to Immuni: 15.1% of citizens with a smartphone have downloaded Immuni. The nearby Trento stops at 10.8%. In Lombardy and Veneto, where the virus has hit hard, to use Immuni are less than 11%. Even less in Valle d’Aosta (9.7%), Piedmont (9.4%) and Friuli Venezia Giulia (8.9%).
The percentage goes up in Liguria (12.4%), Emilia Romagna (13.3%), Marche (12.3%) and Tuscany (12.4%). In the middle of the ranking we find Central Italy with 11.5% in Lazio, 11% in Umbria and 13.1% in Abruzzo. Going down to the South, the percentages also go down: 7.5% in Molise, 6.6% in Campania, 8.3% in Puglia, 7.9% in Basilicata, 9.4% in Sardinia, 6.5% in Calabria and only 5.4% in Sicily, the black jersey of Italian contact tracing.
How many people have to use Immuni?
The Italian average of Immuni adoption, launched on June 5, stops at 9.9%. But is this a sufficient percentage? How many people must adhere to contact tracing for it to be effective? In the first months of the pandemic, information was spread that at least 60% of citizens must be traced, or contact tracing is not effective.
In June, however, new studies have significantly lowered the percentage, bringing it to 15%. If that’s the right percentage, though, only Bolzano, Italy, has enough people using the Immuni app.
