Abstract Background There is limited non-anecdotal literature on the effectiveness of health policies and the prevalence of childhood anemia in rural communities in the Colombian Caribbean region. The objective of the following study is to report a parasitological and hematological episode of 94 children belonging to the child population of Villa Clarín, Colombia, and reinforce the disposable literature of local care reports. Case presentation This article studies an event of intestinal parasitosis prevalence and anemia in 94 children between 1 and 11 years of age, grouped into three age ranges of 1 to 3 years, 4 to 6 years, and 7 to 11 years of age respectively, from the rural community of Villa Clarín, Colombia. Blood samples were obtained by venipuncture and processed through a complete blood count. The feces were collected by spontaneous evacuation and analyzed using a spontaneous sedimentation technique. The prevalence of intestinal parasitosis was 96.81%. Conclusions Eight of the 91 children in whom intestinal parasites were detected had anemia while 29 were above the normal levels of hemoglobin. An association was found with E. histolytica / dispar , but not with A. lumbricoides, T. trichiura, S. stercolaris, Uncinaria, Taenia sp, H. nana, H. diminuta, G. lamblia, T. hominis or B. hominis . The high prevalence of intestinal parasitosis and the anemia levels indicate deficiencies in environmental sanitation and hygienic-sanitary measures.
