PEREZ ARMENGOL, Cristina et al. Epidemiology of the children's intestinal parasitism in the Guadalquivir Valley (Spain). Rev. Esp. Salud Publica [online]. 1997, vol.71, n.6, pp.547-552. ISSN 2173-9110.

BACKGROUND : Intestinal parasitisms represents a public health problem that should be periodically assessed in each region. In the present paper, a study about prevalence of intestinal parasites, has been carried out in children from the natural region of the Guadalquivir Valley. METHODS: During the period 1994-1996, 1.917 children without symptoms, aging between 6 and 10, were studied by means of coprologycal analysis and Graham method, all of them living in 20 villages in the Guadalquivir valley. RESULTS: The overall prevalence of intestinal parasitisms have been of 27,12%. The reported parasites and their prevalence are as follows: Enterobius vermicularis (20,44%), Giardia lamblia (5,05%), Entamoeba coli (2,45%), Endolimax nana (1,61%), Entamoeba histolytica (0,31%), Entamoeba hartmanni (0,05%), Iodamoeba bütschlii (0,05%). CONCLUSIONS: The overall prevalence of intestinal parasites is similar to that found in other spanish region, if only a little bit more favourable probably due to the long lasting drought and the improvements in health resourses, no geohelmints have been detected unlike other protozoosis, giardiasis mantains a relatively high prevalence.
