Abstract
Infections are one of the most common causes of severe neonatal diseases and the leading cause of neonatal death. Although respiratory viral infections are widespread, they are still not recognized as the predominant causes of neonatal deaths. Adenovirus infection is uncommon during the neonatal period, and it frequently has a fatal outcome. Furthermore, it is difficult to distinguish from other common bacterial and respiratory viral infections. The present study reports the case of a 15-day-old newborn who presented with coagulation disorders and hypoxemia in September, 2020. Human adenovirus of species D-53 (HAdV-D53) was detected in the blood and sputum. Severe pneumonia rapidly progressed to multiple organ failure syndrome and the patient succumbed to the disease, despite receiving extracorporeal membrane oxygenation.
