Background:
To explore the epidemiologic and clinical features of, and interactions among, multipathogen infections in hospitalized children with acute respiratory tract infection (ARTI). A prospective study of children admitted with ARTI was conducted. Peripheral blood samples were analyzed by indirect immunofluorescence to detect respiratory agents including respiratory syncytial virus; adenovirus; influenza virus (Flu) types A and B; parainfluenza virus (PIV) types 1, 2, and 3; chlamydia pneumonia; and mycoplasma pneumonia. A medical history of each child was taken.
Results:
Respiratory agents were detected in 164 (51.9%) of 316 children with ARTI. A single agent was identified in 50 (15.8%) children, and multiple agents in 114 (36.1%). Flu A was the most frequently detected agent, followed by Flu B. Coinfection occurred predominantly in August and was more frequent in children between 3 and 6 years of age. A significantly higher proportion of Flu A, Flu B, and PIV 1 was detected in samples with two or more pathogens per sample than in samples with a single pathogen.
Conclusion:
Our study suggests that there is a high occurrence of multipathogen infections in children admitted with ARTI and that coinfection is associated with certain pathogens.
Insights
Multipathogen respiratory infections are common in hospitalized children with acute respiratory tract infection (ARTI). Coinfections, particularly with influenza viruses, are associated with specific pathogens and age groups.
Area of Science:
- Pediatrics
- Infectious Diseases
- Respiratory Medicine
Background:
- Acute Respiratory Tract Infection (ARTI) is a common reason for hospitalization in children.
- Understanding the role of multipathogen infections in pediatric ARTI is crucial for effective management.
- Previous studies have not fully elucidated the interplay of various respiratory pathogens in this population.
Purpose of the Study:
- To investigate the prevalence and characteristics of multipathogen infections in hospitalized children with ARTI.
- To identify specific respiratory agents involved in single and multiple infections.
- To explore potential associations between coinfections and clinical features.
Main Methods:
- A prospective study involving 316 children admitted with ARTI.
- Analysis of peripheral blood samples using indirect immunofluorescence for respiratory viruses and atypical bacteria.
- Collection of detailed medical history for each participating child.
Main Results:
- Respiratory agents were detected in 51.9% of children; 36.1% had multiple agents.
- Influenza A and B were the most frequent agents detected.
- Coinfections were more common in children aged 3-6 years and occurred predominantly in August.
Conclusions:
- Multipathogen infections are frequently observed in hospitalized children with ARTI.
- Certain pathogens, including influenza A, influenza B, and parainfluenza virus 1, are significantly associated with coinfections.
