Professor of Physics at the University of Trento: “The calculation of RT is a false problem. Also because, thanks to vaccinations, it may never return above 1” “The calculation of RT is a false problem. Also because, thanks to vaccinations, it may never return above 1 “. Roberto Battiston, professor of Physics at the University of Trento and careful scholar of the numbers of the pandemic, says this to ‘la Repubblica’ on the dispute over the contagion index. “The RT is defined with a standard written in 2020 after long consultations. Today it would be complicated to change it. Alone it is not enough. And in any case it refers to the situation of about two weeks earlier. Elements that can create a bit of confusion”. “According to my calculations yesterday 0.84. And it continues to fall. To find such a low value, we have to go back to July 2020. How do I determine it? With an algorithm developed by the Physics Department of the University of Trento and which it has also been adopted by Agenas, the National Agency for Regional Health Services. It is perhaps less stringent than that of the CTS but it is certainly more timely. Looking only at Rt can be misleading. For example, one could declare a region red without any it is necessary, only because Rt has exceeded 1. It is also necessary to know how many active infected are compared to the total population “.
