Nemátodos intestinales de importancia médica en Colombia: ¿un problema resuelto?
2001
Intestinal parasites, in general, constitute a great worldwide, public health problem. Of them, nematodes are among the most outstanding in Colombia. Because these parasites can enter into the organism either by ingestion or through the skin, faulty hygienic-sanitary habits facilitate their transmission and conservation. Among nematodosis the more frequent in Colombia are those caused by Ascaris lumbricoides (roundworm), Trichuris trichiura (whipworm), hookworms (Necator americanus and Ancylostoma duodenale) and Strongyloides stercoralis. When the burden of these parasites is considerably high and/or is accompanied by alterations in host defenses, complications can take place that seriously affect health. Presently it is known that pharmacological control of these nematodosis is effective and safe. Nevertheless, without selfcare, and maintenance of good hygienic-sanitary conditions, their eradication will not be feasible. This review of outstanding aspects of nematodosis, with emphasis on their biology, physiopathology, clinical manifestations, diagnosis, treatment, and some epidemiologic data, intends to update physicians as a basis for adequate management of this problem.
