The most common ultrasound findings in confirmed COVID-19 cases were focal and confluent B-lines in the basal and posterior regions of the lung (R1, 85.2%; R2, 77.8%; L1, 88.9%; and L2, 88.9%) and associated pleural involvement (70.4%, 70.4%, 81.5%, and 85.2%, respectively). The sensitivity of point-of-care ultrasound in the diagnosis of COVID-19 was 92.6% (95% CI, 75.7%-99.1%). Specificity was 85.2% (95% CI, 66.3%-95.8%); positive predictive value, 75.8% (95% CI, 59.6%- 91.9%); negative predictiv
