Chagas disease is a parasitic, systemic, and chronic disease caused by the protozoan Trypanosoma cruzi, with risk factors strongly link to low socioeconomic factors. Chagas disease is considered a neglected tropical disease. It is endemic in 21 countries in the Americas, although the migration of in...fected people can transport the disease to non-endemic countries of America and the world.

In areas of Mexico, Central America, and South America, where the Trypanosoma cruzi parasite is present in triatomine bugs, improved housing and spraying insecticide inside housing to eliminate the bugs has significantly decreased the spread of Chagas disease. Screening of blood donations for Chagas... is another important public health tool to help prevent spreading the disease through blood transfusions. Early detection and treatment of new cases, including mother-to-baby (congenital) cases, will also help reduce the burden of disease.

La enfermedad de Chagas (ECha), resultado de la infección por el Trypanosoma cruzi, afecta varias poblaciones de las
zonas rurales de Suramérica y América Central. En los últimos años la enfermedad ha cobrado importancia epidemiológica no sólo porque se ha incrementado la detección de caso...s, sino por la presencia, en la infección crónica, de cardiopatía, patología de considerable gravedad clínica y cuya aparición aumenta el riesgo de incapacidad y reducción de la expectativa de vida.

Objetivo general: Delinear las recomendaciones para la atención médica de niños, adolescentes y adultos infectados por el T. cruzi, en cualquiera de sus fases y formas clínicas. Se espera de esta forma optimizar el uso de recursos y mejorar la calidad de atención de los pacientes, con el fin de... aumentar el número de personas diagnosticadas, controladas y tratadas, y contribuir a disminuir la morbimortalidad y la transmisión de la Enfermedad de Chagas en Argentina.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

DOI: 10.5772/intechopen.102891Little progress has been made since the 1960s and 19. 70s to widen the therapeutic arsenal against Trypanosoma cruzi, the causative pathogen of Chagas disease, which remains a frustrating and perplexing infectious disease. This chapter focuses on the strategic and opera...tional challenges in the clinical drug development of a novel antitrypanosomal agent for Chagas disease. The various elements that contribute to a robust assessment of treatment effect including dose selection, choice of patient population, trial methodology, endpoint measures, and regulatory perspectives are discussed. The learnings herein should serve as resource to help researchers and other stakeholders optimize their clinical development plans and speed delivery of new medicines to patients with Chagas disease.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Chagas disease (American trypanosomiasis) is endemic in 21 countries of the Americas, where control is largely focused on elimination of the domestic insect vectors (Triatominae) coupled with measures to extend and improve the screening of blood donors in order to avoid tranfusional transmission. Th...rough national programmes and multinational initiatives coordinated by WHO-PAHO, much has been accomplished in these domains in terms of reducing transmission. Attention now turns to consolidating the successes in interrupting transmission, and improved treatment for those already infected and those who may become affected in the future. This article, based on technical discussions at the "Epidemiological and Sociological Determinants of Chagas Disease, Basic Information to Establish a Surveillance and Control Policy " meeting in Rio de Janeiro, is designed to open the debate on appropriate strategies for continuation of the successful initiatives against Chagas disease.

A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

La enfermedad de Chagas, también llamada tripanosomiasis americana, sigue siendo endémica en 21 países de América Latina. Sin embargo, como consecuencia de las migraciones, la urbanización, la intensificación del turismo, la modificación de las estrategias agrícolas y el cambio climático, l...a enfermedad ha traspasado el marco rural y el ámbito latinoamericano que le dieron identidad durante decenios, y ha logrado instalarse en la periferia de las ciudades del área endémica y en países de América del Norte, Europa, Asia y Oceanía y transformarse en un problema de salud pública global.

Chagas disease is caused by Trypanosoma cruzi. Infection is transmitted to humans when bitten by Triatominae (reduviid, kissing, or assassin) bugs in South and Central America, Mexico, and very rarely in the US. Less commonly, T. cruzi is transmitted via ingestion of sugar cane juice or food contami...nated with infected Triatominae bugs or their feces, transplacentally from an infected mother to her fetus, or via blood transfusion or an organ transplant from an infected donor.
