Travel through Italy is possible without restrictions even if it is strongly recommended not to travel in this corona time. For some regions: Calabria, Apulia, Sardinia and Sicily you need a corona declaration that must be submitted to the authorities, which can also be submitted online. Information such as the state of health and the last whereabouts are requested. The portals are available in Italian and English and for Sardinia also in German. Additional measures can be decided individually by each region in the event of increasing numbers of infections.
It is also possible to take public transport although it is strongly recommended not to move except for work, study, health reasons or necessary services.
