摘要：This study (March 1977—February 1978) was performed at the Ethio-Swedish Pediatric Clinic, Addis Ababa, to determine whether there were any seasonal fluctuations in the occurrence of diarrhoea associated with enterotoxigenic enterobacteria (ETEB), rotavirus and two parasites ( Giardia lamblia and Entamoeba histolytica ). A total of 1161 children (962 patients and 199 controls) were investigated. ETEB were isolated in 12.2% of the patients and 4.5% of the controls, rotavirus in 27.8% and 8%, and parasites in 6.8% and 1%, respectively. There is a statistically significant difference in the isolation rates between patients and controls (P<0.001 for rotavirus, P<0.01 for ETEB and parasites). Rotavirus was most prevalent in the 7-12 months age group and ETEB during the second year of life, while parasites showed a continuous increase with age. Two peaks in the occurrence of ETEB were found during the year, the first in August (32.6%), the second in January (19.2%). Two peaks for rotavirus though not as distinct as for ETEB, were seen in June (42.7%) and November (36.4%). The isolation rate of parasites showed no consistent pattern during the year. This study suggests a seasonal occurrence of ETEB and rotavirus but with no apparent correlation to climatological factors.
