Patterns and etiology of diarrhea in three clinical settings
Insights
Rotavirus was a common cause of severe acute diarrhea in young children, particularly during winter months. Non-rotavirus, non-bacterial diarrhea also occurred seasonally, but was generally milder.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Background:
- Acute diarrhea is a significant health concern in young children.
- Understanding the etiology and patterns of pediatric diarrhea is crucial for public health.
- Previous studies have not fully elucidated the age, temporal, and clinical characteristics of childhood diarrhea in specific populations.
Purpose of the Study:
- To investigate the age and time patterns of acute diarrhea in young children.
- To characterize the clinical presentation and microbial associations of pediatric diarrhea.
- To estimate the incidence and economic impact of diarrheal illness in southern Michigan.
Main Methods:
- Prospective study conducted from September 1978 to April 1981.
- Involved two pediatric practices and a hospital population in southern Michigan.
- Diarrhea episodes were monitored, and microbial testing was performed to identify pathogens.
Main Results:
- Rotavirus was identified in 16% of diarrhea episodes in children under two, primarily during winter, and associated with more severe illness.
- Bacterial pathogens were rarely found in practice settings (0%) and uncommon in hospitalized patients (5%).
- A seasonal peak of mild, non-rotavirus, non-bacterial diarrhea occurred in the fall, not observed in hospitalized patients.
Conclusions:
- Rotavirus is a major cause of severe pediatric diarrhea, with distinct seasonal patterns.
- Most childhood diarrhea in this setting was not attributable to bacterial pathogens.
- Hospitalization represented a greater direct cost to society than outpatient care for diarrheal illness.
Abstract:
Acute diarrhea of young children was studied from September 1978 to April 1981 to determine age and time patterns, clinical characteristics and microbial association in two pediatric practices and in a hospital population in southern Michigan. The practice population sizes were estimated so that rates of diarrhea could be determined. Care was sought for about 0.85 episodes per child in the first year of life and 0.4 episodes in the second year of life. Bacterial pathogens were rarely identified in the practices and were identified in only 5% of hospitalized patients. Rotavirus was identified in 16% of the episodes in children under two years of age in the practices. These rotavirus diarrheas occurred mainly in the winter and were clearly more severe than nonrotavirus diarrheas. The rotavirus-infected patients did not, however, have more frequent respiratory symptoms. Respiratory symptom frequency was related to practice setting and income but not etiology. In the fall, before the rotavirus seasonal peak, a peak of nonrotaviral, nonbacterial diarrhea was seen in the practices. The symptoms were mild and a corresponding peak was not seen in hospital patients. The total direct costs of diarrheal illness to society were estimated to be due more to hospitalization than to outpatient care.
