Introduction: On February 20, 2020, a severe case of pneumonia due to SARS-CoV-2 was diagnosed in northern Italy (Lombardy). Some studies have identified obesity as a risk factor for severe disease in patients with COVID-19. The purpose of this study was to investigate the incidence of SARS-CoV-2 infection and its severity in patients who have undergone bariatric surgery. Material and Methods: During the lockdown period (until May 2020), we contacted operated patients by phone and social networks (e.g., Facebook) to maintain constant contact with them; in addition, we gave the patients a dedicated phone number at which to call us for emergencies. We produced telemedicine and educational videos for obese and bariatric patients, and we submitted a questionnaire to patients who had undergone bariatric surgery in the past. Results: A total of 2145 patients (313 male; 1832 female) replied to the questionnaire. Mean presurgical BMI: 44.5 ± 6.8 kg/m2. Mean age: 44.0 ± 10.0 year. Mean BMI after surgery: 29.3 ± 5.5 kg/m2 (p < 0.05). From February to May 2020, 8.4% of patients reported that they suffered from at least one symptom among those identified as related to SARS-CoV-2 infection. Thirteen patients (0.6%) tested positive for COVID-19. Six patients (0.3%) were admitted to the COVID Department, and 2 patients (0.1%) were admitted to the ICU. Conclusions: Although the reported rates of symptoms and fever were high, only 0.6% of patients tested positive for COVID-19. Among more than 2000 patients who underwent bariatric surgery analyzed in this study, only 0.1% needed ICU admission.

Abstract
Introduction: On February 20, 2020, a severe case of pneumonia due to SARS-CoV-2 was diagnosed in northern Italy (Lombardy). Some studies have identified obesity as a risk factor for severe disease in patients with COVID-19. The purpose of this study was to investigate the incidence of SARS-CoV-2 infection and its severity in patients who have undergone bariatric surgery. Material and Methods: During the lockdown period (until May 2020), we contacted operated patients by phone and social networks (e.g., Facebook) to maintain constant contact with them; in addition, we gave the patients a dedicated phone number at which to call us for emergencies. We produced telemedicine and educational videos for obese and bariatric patients, and we submitted a questionnaire to patients who had undergone bariatric surgery in the past. Results: A total of 2145 patients (313 male; 1832 female) replied to the questionnaire. Mean presurgical BMI: 44.5 ± 6.8 kg/m2. Mean age: 44.0 ± 10.0 year. Mean BMI after surgery: 29.3 ± 5.5 kg/m2 (p < 0.05). From February to May 2020, 8.4% of patients reported that they suffered from at least one symptom among those identified as related to SARS-CoV-2 infection. Thirteen patients (0.6%) tested positive for COVID-19. Six patients (0.3%) were admitted to the COVID Department, and 2 patients (0.1%) were admitted to the ICU.
