Community-acquired infections among children in an urban environment: a 2-year prospective study in Liverpool, U.K
1Department of Microbiology and Infection Control, Royal Liverpool Children's Hospital, U.K.
Insights
This study analyzed 1,599 pediatric hospital admissions for community-acquired infections over two years. Respiratory infections and gastroenteritis were most common, particularly in infants, highlighting the need for ongoing surveillance.
Area of Science:
- Pediatric Infectious Diseases
- Clinical Microbiology
- Public Health Surveillance
Background:
- Community-acquired infections are a significant reason for pediatric hospital admissions.
- Understanding infection patterns is crucial for effective public health and hospital resource management.
- Previous local data on pediatric infection epidemiology was limited.
Purpose of the Study:
- To investigate the patterns and seasonal distribution of community-acquired infections in hospitalized children.
- To assess the role of laboratory diagnostics in identifying causative agents.
- To provide local epidemiological data for public health and hospital planning.
Main Methods:
- A 2-year prospective study involving 1,599 children admitted with infections to a children's hospital.
- Data collection included infection type, patient demographics, and laboratory investigations.
- Analysis focused on identifying common pathogens and their seasonal variations.
Main Results:
- Respiratory infections (32%) and gastroenteritis (28%) were the leading causes of admission.
- Infants under 1 year constituted 64% of all admissions.
- A causative agent was identified in 21% of cases, with distinct seasonal patterns for specific pathogens (e.g., RSV in winter, Salmonella in summer).
Conclusions:
- Respiratory infections and gastroenteritis are major contributors to pediatric hospitalizations, especially in infants.
- Laboratory investigations are essential for pathogen identification, though success rates can be improved.
- The findings underscore the importance of continuous surveillance of community-acquired infections for public health initiatives.
Abstract:
Community-acquired infections are an important cause of admission of children to hospital. We have made a 2-year prospective study of 1,599 children admitted with infection to the Royal Liverpool Children's Hospital in order to determine the pattern of infections, their seasonal distribution and the role of the laboratory in isolating causative agents. Respiratory infections (32% cases) and gastroenteritis (28% cases) were the principal causes of admission. Of all admissions, 64% were children aged less than 1 year. Appropriate specimens were obtained and/or investigations made of 48% cases. Overall, a causative agent was determined in 21% cases. Individual pathogens showed marked seasonality. Respiratory syncytial virus, rotavirus and Shigella species were found more often in the winter months, while Salmonella species and adenovirus infections were most common in the summer. The results provide local data that is relevant to both public health and hospital planning. They also emphasise the need for continuing surveillance of community-acquired infections.
