Once the Covid-19 pandemic started spreading in Italy, Luigi Cavanna, the head of the Oncology ward in Piacenza Hospital, decided that the best way to approach the disease was to treat it early, in the same way you would treat cancer. Equipped with a device that monitors the level of oxygen in the blood and a portable ultrasound chest scanner, doctor Cavanna started visiting patients at their home - treating them mostly with hydroxychloroquine. In this way, he saved more than 365 patients. Only a small percentage saw their condition worsen to the point where they needed to be hospitalized.
