초록
Coinfection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with other respiratory pathogens may complicate diagnosis and treatment. Since the risk of coinfection with SARS-CoV-2 is expected to increase during the influenza epidemic period, it is necessary to study the clinical course of coinfection. To our knowledge, there have been a few cases of coinfection between SARS-CoV-2 and influenza virus in neonates. Here, we report the clinical course of a neonate who was coinfected with the influenza virus and SARS-CoV-2. A 20-day-old boy born with low birth weight presented with a fever. The patient was confirmed as positive with coronavirus disease 2019 (COVID-19) and influenza B by real-time polymerase chain reaction at admission, whereas his mother was only COVID-19 positive at that time. Initial chest x-ray revealed hyperinflation and increased peribronchial markings at the right lower lung bronchus, but slightly decreased lung sounds without crackle or wheezing at admission. We administered empirical antibiotics for neonatal sepsis and oseltamivir for influenza B. On the chest x-ray follow-up, the findings showed improvement. After discharge, the patient showed a stable general condition. Children ineligible for COVID-19 vaccination who are coinfected with SARS-CoV-2 and the influenza virus are more likely to develop severe symptoms. It is necessary to detect coinfections as some can be treated with antibiotics and antivirals in young infants.
Abstract
Coinfection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with other respiratory pathogens may complicate diagnosis and treatment. Since the risk of coinfection with SARS-CoV-2 is expected to increase during the influenza epidemic period, it is necessary to study the clinical course of coinfection. To our knowledge, there have been a few cases of coinfection between SARS-CoV-2 and influenza virus in neonates. Here, we report the clinical course of a neonate who was coinfected with the influenza virus and SARS-CoV-2. A 20-day-old boy born with low birth weight presented with a fever. The patient was confirmed as positive with coronavirus disease 2019 (COVID-19) and influenza B by real-time polymerase chain reaction at admission, whereas his mother was only COVID-19 positive at that time. Initial chest x-ray revealed hyperinflation and increased peribronchial markings at the right lower lung bronchus, but slightly decreased lung sounds without crackle or wheezing at admission. We administered empirical antibiotics for neonatal sepsis and oseltamivir for influenza B. On the chest x-ray follow-up, the findings showed improvement. After discharge, the patient showed a stable general condition. Children ineligible for COVID-19 vaccination who are coinfected with SARS-CoV-2 and the influenza virus are more likely to develop severe symptoms. It is necessary to detect coinfections as some can be treated with antibiotics and antivirals in young infants.
