GENOA, ITALY - JULY 22: A recovered Coronavirus patient is tested at the Department of Rehabilitative Cardiology of ASL 3 Genova on July 22, 2020 in Genoa, Italy. There is an estimated 14 million confirmed Coronavirus cases worldwide, with a reported 8 million recovering patients. In 80 percent of COVID-19 cases, recovery is complicated, leaving physical and psychological consequences that do not easily subside or allow survivors to return to normal life. The first Covid veterans gym, a project of Genoa's ASL 3 and rehabilitation cardiology department directed by cardiologist Piero Clavario, aims to address this. Designed to reactivate the heart, muscles and lungs, the gyms rehabilitation process gives patients a 2-month protocol, overseen by a staff of four doctors, three nurses, one psychologist and a physiotherapist. Of approximately 700 patients who were previously hospitalized with Covid, 100 patients were selected to participate in the gym, with the first 12 patients now six weeks into their rehabilitation process. Treatment is designed to combat numerous effects of the disease. Half of all patients hospitalized for Covid will be left with lung fibrosis, causing difficulty breathing. The nervous system is also affected as evidenced by the loss of taste and smell. Meanwhile 80 percent of patients suffer cognitive impairments such as memory loss and orientation difficulties, 40 percent show symptoms of depression and others experience chronic fatigue and rapid weight loss.
