Abstract
Prevalence and transmission of intestinal parasitosis in human beings from Zona da Mata, Minas Gerais, Brazil
Highlights
Worldwide, parasites, protozoa and pathogenic helminthes affect around more than two million people (MORRONE et al, 2004)
Ancylostoma duodenale appeared in 3.57% and Strongyloides stercoralis was the third highest prevalence of helminths, 1.91%
Among the most frequently helminths worldwide around 25-30% of the worldwide population is infected with Ascariasis each year, with at least 10.000 deaths, mostly children, due to complications resulting from infections, as chronicity and intestinal obstruction (SILVA, 2005; SILVA et al, 1997)
Summary
Parasites, protozoa and pathogenic helminthes affect around more than two million people (MORRONE et al, 2004). Intestinal parasites are responsible for high morbidity, which is an important determinant of infant morbidity and mortality (OLIVEIRA, 2004). In Brazil, intestinal parasites are still a serious problem for the public health, causing significant morbidity and mortality, which is an important health and social problem, mainly in low socioeconomic level of the population (BARRETO, 2006). Ascariasis, trichuriasis, hookworm infections and some intestinal nematodiasis are among the neglected tropical diseases of high importance and impacts on public health, but are not restricted to tropical and subtropical regions (ANDRADE et al, 2010). Parasites can cause several injuries to the hosts, such as intestinal obstruction (Ascaris lumbricoides), malnutrition (A. lumbricoides and Trichuris trichiura) iron deficiency anemia (hookworm), abdominal pain, nausea and weight loss (Taenia sp.), diarrhea and poor absorption (Entamoeba histolytica, Isospora belli and Giardia lamblia). Clinical manifestations are dependent on the type of parasite and health status of the patient (FERREIRA et al, 2000; LINDSAY et al, 2007; PFUETZENREITER; PIRES et al, 2000)
