Sicilian health chief probed over 'altered' COVID data Carabinieri police put a number of people under house arrest and Sicilian Health Chief Ruggero Razza has been placed under investigation over allegations the COVID-19 figures the region sent to the national authorities were altered, sources said on Tuesday. The people put under house arrest worked for the DASOE unit of the Sicilian health department, the sources said. They allegedly changed the number of new COVID cases and the number of tests done in data sent to the Higher Health Institute (ISS) as part of a "heinous political design" to stop Sicily being classed as a high-risk red zone and put into lockdown.
