[Prevalence of intestinal helminths in three regions of Minas Gerais State].
A parasitological assay of feces, through the Kato-Katz method, was undertaken in 18,973 schoolchildren (7 to 14 years old), at primary school level, from a public school of the State of Minas Gerais. Three mesoregions were studied: Tri ngulo Mineiro/ Alto Para ba ( 60 municipalities); northwest Minas Gerais (13) and south/south-west regions of Minas Gerais (144). Among the examined children, 15,545 (82%) were negative; 2,863 (15%) were infected with a single species of helminthes and 565 (3%) were infected by more than one species. The prevalence rates were: A. lumbricoides 10.3%; T. trichiura 4.7%; hookworm 2.9%; E. vermicularis 1.2%; H. nana 0.4% and Taenia sp 0.2%. The largest helminthes prevalence/mesoregion were for T. trichiura (24.2%) and A. lumbricoides (18.7%) in the south/south-west region; hookworm (12.1%) and Taenia sp (0.7%) in the northwest region of Minas Gerais. Intestinal helminthiasis is still regarded as a serious public health problem, including regions where the socio-economic conditions are more favorable.
