Pneumococcal carriage in children with COVID-19

Area of Science:

• Pediatric Infectious Diseases
• Microbiology
• Virology

Background:

• Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is a novel virus causing the COVID-19 pandemic.
• Streptococcus pneumoniae is a significant human pathogen, but its interaction with SARS-CoV-2 remains unclear.
• Understanding coinfections is crucial for managing pediatric respiratory illnesses.

Purpose of the Study:

• To investigate the relationship between SARS-CoV-2 infection and Streptococcus pneumoniae carriage in pediatric patients.
• To determine if S. pneumoniae coinfection influences the clinical presentation or severity of COVID-19 in children.

Main Methods:

• Retrospective analysis of medical records from pediatric patients tested for SARS-CoV-2.
• Nasopharyngeal specimens were analyzed for both SARS-CoV-2 and S. pneumoniae.
• Data from 829 pediatric patients were evaluated.

Main Results:

• A higher nasopharyngeal carriage rate of S. pneumoniae was observed in SARS-CoV-2 positive children (32.2%) compared to SARS-CoV-2 negative children (14.1%).
• No statistically significant differences were found in clinical characteristics, laboratory findings, or disease severity between patients with and without S. pneumoniae positivity, regardless of SARS-CoV-2 status.
• Pneumococcal carriage did not appear to affect the course of COVID-19 disease.

Conclusions:

• Pediatric patients with COVID-19 exhibit an increased rate of nasopharyngeal Streptococcus pneumoniae carriage.
• Streptococcus pneumoniae carriage does not seem to alter the clinical course or severity of COVID-19 in children.
• The implications of increased pneumococcal carriage during the pandemic warrant further investigation, highlighting the importance of pneumococcal vaccination.
