The youngest surviving COVID-19 patient: A case report.

Introduction And Importance: Vertical transmission of the novel coronavirus, known as severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has not yet been proven. However, several case reports and case series worldwide, including ours, support this certain type of transmission. Although COVID-19 has been mostly treated supportively, in some cases, including ours, medical treatment seems to be essential.

Case Presentation: Herein, we present a case of a neonate born to an asymptomatic mother with no known history of COVID-19 during pregnancy who was diagnosed as an asymptomatic silent carrier following the confirmation of COVID-19 in her newborn. Although bacterial pneumonia, early-onset sepsis, and meconium aspiration syndrome were the possible differential diagnosis, positive COVID-19 real-time reverse transcriptase-polymerase chain reaction (RT-PCR) confirmed the diagnosis. Due to the neonate's critical lung involvement leading to a critical condition, remdesivir, intravenous immune globulin (IVIG) and corticosteroid were administered. The patient fully recovered and was discharged after around 20 days.

Clinical Discussion: Although treatment in most cases of neonatal COVID-19 has been mainly supportive, in a few case reports remdesivir, corticosteroids and IVIG have been successfully used. Since a satisfying clinical improvement was not noticed following sepsis workup, all the three aforementioned medications were administered.

Conclusion: Immunomodulatory medications as well as antiviral therapy should be considered in severe neonatal COVID-19 cases, as were shown to be lifesaving in our patient. Interestingly, to date, this case seems to be the youngest survived patient who has received medicines other than supportive care.
