Congenital transmission of Chagas disease has not been extensively studied in Colombia, and there are no standardized processes in the health system regarding
the specific diagnosis, treatment and follow-up of this disease. To generate recommendations on congenital Chagas disease and Chagas in wom...en of childbearing
age in Colombia, a consensus of experts was developed. An extensive literature search through the Medline database was carried out using the MeSH terms:
«Chagas disease/congenital», «prevention and control», «diagnosis», «therapeutics» and «pregnancy». Appropriate abstracts were selected and the full texts were
analyzed. The relevant information was synthesized, classified, and organized into tables and figures and was presented to a panel of experts, which was composed
of 30 professionals from various fields. Based on the Delphi methodology, three rounds of consultation were conducted. The first and second rounds were based
on electronic questionnaires that measured the level of consensus of each question among the participants. The third round was based on a face-to-face discussion focusing on those questions without consensus in the previous consultations. The evidence was adapted to national circumstances on a case-by-case basis,
and the content the final document was approved. These recommendations are proposed for use in routine medical practice by health professionals in Colombia.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is a significant public health problem, affecting millions of people worldwide. And although it was described 110 years ago, only two old nitroheterocyclic drugs, benznidazole and nifurtimox, are cu...rrently available for the treatment of Chagas disease and both have several limitations. Besides the clear unmet medical need, many challenges preclude the development of new treatments, some of them related to a lack of understanding of the pathophysiology of the disease and parasite-host interactions. New knowledge and tools are becoming available, but the number of new chemical entities progressing through the preclinical pipeline is inadequate. Therefore, it is still uncertain whether safe, effective and accessible new drugs will be available in the near future. The Chagas disease research community must commit to even greater collaboration to ensure that patients eventually benefit from better treatments.

The Chagas disease is frequently referred to as the effects that the parasite Trypanosoma cruzi (T. cruzi) has on people’s health. However, from our perspective, Chagas is much more than that: it is a complex socioenvironmental health problem in which elemen...ts of different nature converge and interact. The biomedical and epidemiological aspects, which are most frequently addressed, are only a piece of the puzzle that needs to be complete in order to understand Chagas in all its complexity. Social, environmental, economic, political, cultural, and educational elements turn out to be essential in comprehending the magnitude of the problem without prejudice or stigmatizations.

Chagas disease, also known as the “kissing disease,” is considered one of the Neglected Tropical Diseases (NTDs), which are diseases that have been forgotten by developed countries because they usually plague lower-income countries.
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. Teniendo en cuenta que el Chagas afecta a poblaciones en situación de pobreza en las que produce graves consecuencias para la salud y la economía de las personas infectadas, y que los recursos orientados a fomentar el desarrollo de proyectos de investigación, estrategias de control y planes de atención médica a los pacientes detectados son escasos, la Organización Mundial de la Salud (OMS) incorporó esta enfermedad al grupo de enfermedades infecciosas desatendidas (EID) en el año 2005. Se reconoce actualmente la naturaleza multidimensional de la enfermedad de Chagas, cuya caracterización contempla una intrincada trama de aspectos socioculturales, políticos, biológicos, ambientales y sanitarios. Parte sustancial de todo ello radica en el carácter zoonótico de la endemia y la consiguiente imposibilidad de su erradicación. Por ende, resulta muy complicada la construcción de la ruta crítica para enfrentar esta enfermedad, con la aspiración o el objetivo de su eliminación como problema de salud pública. El propósito de esta guía es ofrecer a los Estados Miembros un instrumento que permita actualizar y estandarizar los procesos de evaluación del control, verificación de la interrupción de la transmisión, y validación de la eliminación de la enfermedad de Chagas como problema de salud pública, en consonancia con: a) la Estrategia y plan de acción para la prevención, el control y la atención de la enfermedad de Chagas; b) el Plan de acción para la eliminación de las enfermedades infecciosas desatendidas y las medidas posteriores a la eliminación 2016-2022; c) el Plan de acción sobre entomología y control de vectores 2018-2023; d) guías o procedimientos operativos estandarizados existentes para la verificación o validación de la eliminación de otras enfermedades infecciosas desatendidas (EID) como la oncocercosis, la filariasis linfática y el tracoma, y e) Enfermedades tropicales desatendidas. Prevención, control, eliminación, erradicación.

Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical man...ifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%-60%), followed by heart failure (25%-30%) and stroke (10%-15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

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.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

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.
