Operation of ultrasonography services in a dedicated paediatric hospital and a university hospital in Greece under the COVID-19 pandemic.

Ultrasonography (US) is one of the most common diagnostic imaging tests in children. During the coronavirus disease 2019 (COVID-19) pandemic, it is important to operate with a plan designed to protect health care workers, to prevent transmission of infection from child and parents to another child or an accompanying person in the US suite, and to save valuable protective material and resources. Measures during routine US in children can be challenging both in general hospitals with paediatric units and in dedicated paediatric hospitals.
