Respiratory viruses in children admitted to hospital in Edinburgh 1972-1985
1Regional Virus Laboratory, City Hospital, Edinburgh.
Abstract:
The temporal incidence of respiratory viruses identified in children admitted to an Edinburgh hospital over a period of 14 years, 1972-1985, is described, Respiratory syncytial (RS) virus was identified most often, usually (but not in 1979 and 1985) with single peaks of activity in the winter months. Influenza virus infections were seen in the winter and spring but we failed to find evidence of interference between RS and influenza virus. Of the viruses studied, the parainfluenza viruses were the least predictable in their epidemiological behaviour. The results of this study are compared with those of others and the role of certain aspects of the weather is considered.
Insights
This 14-year study of pediatric respiratory virus infections in Edinburgh found respiratory syncytial (RS) virus to be the most common. Parainfluenza viruses showed unpredictable patterns, while influenza occurred in winter and spring.
Area of Science:
- Pediatric infectious diseases
- Virology
- Epidemiology
Background:
- Understanding the temporal patterns of respiratory virus circulation in children is crucial for public health planning.
- Long-term surveillance data provides insights into viral epidemiology and potential co-circulations.
Purpose of the Study:
- To describe the temporal incidence of common respiratory viruses in hospitalized children over a 14-year period (1972-1985).
- To analyze the seasonality and potential interactions between different respiratory viruses.
Main Methods:
- Retrospective analysis of laboratory-confirmed respiratory virus detections in pediatric hospital admissions.
- Epidemiological analysis of incidence data over a 14-year period.
Main Results:
- Respiratory syncytial (RS) virus was the most frequently identified virus, typically peaking in winter months (except 1979 and 1985).
- Influenza virus infections were observed during winter and spring, with no evidence of interference with RS virus.
- Parainfluenza viruses exhibited the least predictable epidemiological behavior among the studied viruses.
Conclusions:
- Respiratory syncytial virus demonstrates a consistent, though occasionally variable, winter seasonality in pediatric populations.
- The study highlights the complex and often unpredictable nature of respiratory virus epidemiology in children.
- Further research into environmental factors, such as weather, may offer additional insights into viral transmission patterns.
