| Outline of Final Research Achievements |
A prospective community based diarrheal study was conducted in a typical agricultural area in Nam Dinh province in northern Vietnam in the study period. A 300 out of approx. 2,100 households were randomly chosen, and stool samples and epidemiological data were collected in order to estimate 1) distributions of etiological agents of; and 2) possible risk factors for diarrhea. Approximately 1,200 diarrheal sapmles were collected and analyzed in the study, and rotavirus, adenovirus, any categories of diarrheagenic Escherichia coli, Clostridium difficicile, and Entoamoeba histolytica were estimated as significant etiologies of diarrhea including mild to moderate cases in the community. Approximately 20% of the all households raised livestock animals including cows, pigs, and poultry, and of those, cow raising was estimated to be a risk factor for Giardia infections, one of the intestinal protozoa to cause diarrhea, in Hien Khanh commune.
