Viral infections of the upper airway tract are quite common in infants and children. Many types of viruses, mainly respiratory viruses, cause ear, nose, and throat (ENT) infections. Clinically significant respiratory viruses are respiratory syncytial virüs (RSV), rhinovirus, parainfluenza virus, coronavirus, influenza virus, adenovirus, human metapneumovirus, and bocavirus. At the end of 2019, a novel coronavirus, designated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent of coronavirus disease 2019 (COVID-19), is identified, and it also causes symptoms and signs of acute upper respiratory tract infection (URTI). Respiratory viruses affect all age groups; however, viral infection incidence is exceptionally high in infants and young children, and they have 6–8 infection episodes per year [1, 2].
