Horizontal Transmission of COVID-19 in a 24-Week Premature Infant and Post-discharge Follow-Up

Le résumé fourni par la source

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has rapidly spread across the globe. The clinical spectrum of infection with SARS-CoV-2 among the most vulnerable extremely premature patient population in the neonatal intensive care units (NICUs), particularly those with chronic lung disease (CLD), remains unclear. Additionally, post-COVID conditions have been described in children with limited published data among infants. Symptoms in children appear similar to those described in the adults. We report a case of SARS-CoV-2 infection in a 24-week preterm infant with CLD acquired via horizontal transmission while still in the NICU. We also provide follow-up data on patient until one year post-discharge. Our patient developed fever prompting testing for SARS-CoV-2. Although extremely premature infants with CLD are known to be at high risk for morbidities if they acquire respiratory viral infections, infection with SARS-CoV-2 in this case report presented with relatively mild clinical symptoms. He remained clinically stable on respiratory support (nasal cannula) with eventual weaning to room air. Our patient was followed until one year post-discharge (chronological age: 20 months) and had follow-up by various subspecialties for chronic lung disease, hypothyroidism, chronic kidney disease, and poor growth. We did not observe any specific post-COVID symptoms. This case illustrates that horizontal transmission of SARS-CoV-2 infection among extremely premature infants with CLD is possible in the NICU but likely presents with mild clinical symptoms during acute infection and less chances of post-COVID conditions. Additionally, this case highlights the need for adherence to infection prevention guidelines to prevent nosocomial transmission amid the ongoing pandemic.
