Insights
Diarrhea in Kenyan children under five was frequently caused by bacterial and viral agents, with diarrhogenic Escherichia coli being the most common. Fecal contamination in drinking water was identified as a likely source of these infections.
Area of Science:
- Microbiology
- Public Health
- Pediatrics
Background:
- Diarrhea is a significant health concern for children under five in Kenya.
- In 1993, diarrhea ranked as the 5th most frequent disease among outpatients, affecting approximately 800,000 individuals.
- Understanding the specific etiologies of childhood diarrhea is crucial for effective intervention.
Purpose of the Study:
- To identify the microbiological agents responsible for diarrhea in young children in Kenya.
- To investigate the potential link between drinking water contamination and the prevalence of childhood diarrhea.
- To inform public health strategies for diarrhea prevention and control.
Main Methods:
- Microbiological examination of fecal specimens from 1,362 children under five with diarrhea.
- Identification of major diarrheagenic agents including bacteria (e.g., E. coli, Shigella, Salmonella) and parasites (e.g., Entamoeba histolytica, Giardia lamblia).
- Bacteriological analysis of drinking water samples from patients' households.
Main Results:
- Diarrheagenic agents were detected in 56.3% of fecal specimens.
- The most prevalent causative agents were diarrhogenic Escherichia coli (17.2%), Rotavirus (11.4%), Shigella spp. (6.3%), Entamoeba histolytica (5.8%), Salmonella spp. (5.4%), and Giardia lamblia (3.6%).
- Enterobacteriaceae, indicative of fecal contamination, were frequently found in household drinking water samples.
Conclusions:
- Diarrhea in young Kenyan children is often caused by a variety of infectious agents.
- Contaminated drinking water is a probable source of fecal pathogens leading to diarrhea.
- Public health interventions should focus on improving water quality and sanitation to reduce childhood diarrhea.
Abstract:
I participated in a project concerning diarrhea in children caused by bacteria (Japan International Cooperation Association) in the Republic of Kenya between April 1993 and March 1994. According to the Health Information Report by the Ministry of Health in 1993, diarrhea was at the 5th most frequent disease among outpatients and these patients numbered about eight hundred thousand. On microbiological examination, diarrhoegenic agents were detected from 767 of 1,362 (56.3%) fecal specimens collected from children under five years of age with diarrhea. Major causative agents were diarrhogenic Escherichia coli (DgEC), Rota virus, Shigella spp., Entamoeba histolytica, Salmonella spp., and Giardia lamblia, which were detected from 17.2%, 11.4%, 6.3%, 5.8%, 5.4% and 3.6%, respectively. The results suggested that diarrhea was caused by drinking water with fecal contamination. We bacteriologically examined drinking water in the patients' houses, and many Enterobacteriaceae were detected in most of the specimens.
