Tricuriasis

Abstract

Introduction: Whipuriasis, from the helminthiasis group, is one of the intestinal parasitoses that are transmitted through contact with soil, ingestion of contaminated water and food. It is highly prevalent in Brazil, especially in the North and Northeast regions. Objectives: The chapter focuses on elucidating the topic addressed, deepening clinical and epidemiological aspects and their forms of control. Etiological agent: species Trichuris trichiura, of the family Trichuridae. Evolutionary forms: It has the following evolutionary forms: egg, larva (L1, L2, L3 and L4) and adult worm. Form of contamination: The most common form of contamination is through ingestion of eggs, through contact with contaminated soil or contaminated food and water.  Biological cycle: cycle begins with eggs eliminated in the feces. The eggs remain in the soil, and larvae develop inside and then contaminate water and food that humans can ingest. In humans, the eggs release the larvae that will parasitize and mature in the host's large intestine. Clinical manifestation: Patients may be asymptomatic, and when symptomatic, the complaints are abdominal pain, nausea, vomiting, insomnia, and weight loss. In more severe cases of severe intestinal infections, it may present with enterorrhagia and cases of rectal prolapse in children. Diagnosis: Performed primarily by parasitological examination of feces. Treatment: Done by administering anthelmintics such as Albendazole and Mebendazole. Prophylaxis: the prevention of Tricuriasis is done through health education, treatment of the sick, control of the supply of irrigation of fruits and vegetables, as well as the implementation of basic sanitation. Conclusion: The chapter addresses the theme of Tricuriasis, going through its clinical manifestations, treatment and forms of control in an updated and in-depth way, in order to provide accessible information, contributing to the improvement of prevention and possible reduction of cases.
