Lung ultrasound in outpatient approach to children with suspected COVID 19

In the absence of reliable, highly sensitive diagnostic tests or when nasal swab is unworkable or there are too many requests to be performed quickly due to the pandemic, LUS should be used in children with persistent cough for whom a CV19 is suspected because it can highlight undiagnosed interstitial lung lesions and reinforce the diagnostic suspicion of CV19 This approach can be very useful in outpatient settings and in areas with limited medical resources such as developing countries.
