Figure 1 Lung ultrasound findings in children with viral lower respiratory tract infection (a, c) and in a woman with COVID-19 pneumonia (a, d), performed by the same pediatrician.
1a Lung ultrasound images of a 4 year old boy with viral pneumonia - due to Coronavirus (non-COVID-19), Bocavirus and Metapneumovirus coinfection- requiring respiratory assistance with High-flow nasal oxygen at the pediatric department; ; lung ultrasound shows areas of white lung with multiple, coalescent vertical artifacts (B-lines, black arrowhead). A similar lung ultrasound pattern (multiple vertical artifacts, B-lines, black arrowhead) was found in a 42 years old woman with COVID-19 pneumonia and moderate respiratory distress (1b ). 1c Lung ultrasound images of a 2 year old boy with H1N1 Influenza pneumonia requiring respiratory assistance with High-flow nasal oxygen at the pediatric department, showing subpleural consolidations (hypoechoic areas, black arrow) and below areas of white are evident. A similar lung ultrasound pattern (subpleural consolidations - black arrow – with areas of white lung) was found in a 31 years old pregnant woman with COVID-19 pneumonia and acute respiratory failure requiring admission in the intensive care unit (1d ).
