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.

Chagas disease is found mainly in endemic areas of 21 continental Latin American countries. The most common way people are infected with Chagas is through the blood-sucking triatomine bugs, also known as ‘kissing bugs’ (or vinchuca, barbeiro, pito, chinche, chipo in different Latin American coun...tries). The bugs typically live in wall or roof cracks of poorly constructed homes made of materials such as mud, straw and palm thatch. They come out at night to feed on people’s blood while they’re sleeping, then defecate close to the bite. Their faeces contain the parasite, which can then enter the person’s body when they inadvertently smear the bug’s waste into the bite or another skin break, the eyes or the mouth.

Chagas disease, also known as American trypanosomiasis, is a potentially life-threatening illness caused by the protozoan parasite Trypanosoma cruzi. About 6–7 million people worldwide are estimated to be infected with T. cruzi. The disease is found mainly in endemic areas of 21 continental Lati...n American countries, where it has been mostly transmitted to humans and other mammals by contact with faeces or urine of triatomine bugs (vector-borne), known as kissing bugs, among many other popular names, depending on the geographical area.

Little progress has been made since the 1960s and 1970s 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 operational challenges in the clinica...l 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.

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

Principaux faits
D’après les estimations, 6 à 7 millions de personnes dans le monde sont infectées par Trypanosoma cruzi (T. Cruzi), le parasite responsable de la maladie de Chagas. La plupart de ces personnes vivent en Amérique latine.
La transmission à l’être humain se fait principalem...ent, en Amérique latine, par l’intermédiaire d’un insecte appelé triatome, qui peut être porteur de T. cruzi.
Parmi les autres modes de transmission de la maladie de Chagas, figurent : la transmission orale (par voie alimentaire), la transfusion de sang ou de produits sanguins, la transmission mère-enfant (congénitale), la transplantation d’organes et les accidents de laboratoire.
La maladie de Chagas ne touchait auparavant que des zones rurales de la Région des Amériques, et surtout de l’Amérique latine. Ces dernières décennies, toutefois, les mouvements de population ont fait que la plupart des personnes infectées sont des habitants de zones urbaines (urbanisation) et que la maladie s’est propagée à d’autres continents (où T. cruzi se transmet par des voies non vectorielles).
L’infection à T. cruzi est curable si un traitement est instauré rapidement après l’infection.
Chez les personnes infectées de façon chronique, un traitement antiparasitaire peut éventuellement prévenir ou enrayer la progression de la maladie, et éviter sa transmission, notamment de la mère à l’enfant.
Jusqu’à 30 % des personnes infectées de façon chronique présentent des troubles cardiaques, et jusqu’à 10 % d’entre elles souffrent de troubles digestifs et/ou neurologiques, ce qui peut imposer un traitement particulier.
Les principales méthodes de prévention de la maladie de Chagas en Amérique latine sont la lutte antivectorielle ainsi que d’autres stratégies visant à réduire la transmission vectorielle.
Dans le monde entier, le dépistage sanguin joue un rôle crucial dans la prévention de l’infection par transfusion ou transplantation d’organes.
Il est essentiel de détecter et de traiter l’infection chez les femmes et les filles en âge de procréer, ainsi que de soumettre tout nouveau-né et ses frères et sœurs à un dépistage dans le cas où la mère est infectée et n’a jamais reçu de traitement antiparasitaire.
Certains facteurs socio-économiques et environnementaux influent fortement sur la maladie de Chagas, dont la propagation et les différentes dimensions interdépendantes justifient la nécessité de mettre en œuvre des stratégies de lutte multisectorielles.
Quelques pays ont mis en place la notification et la surveillance des cas aigus et chroniques et des voies de transmission actives, qui sont essentielles à la lutte contre la maladie de Chagas.

Recovery from COVID-19 has been challenging in Guatemala. As a result of the prolonged socio-economic impact of the pandemic, the average poverty rate nationwide has increased by almost 5%. This rise in the poverty level further exacerbates preexisting vulnerabilities and erodes the limited safety n...ets available to vulnerable populations. Year after year, recurrent disasters and humanitarian crises aggravate the historic social gaps that result in high levels of vulnerability, multidimensional poverty, and overall deprivation of essential services among hundreds of thousands of Guatemalans. According to the World Risk Report 2020, Guatemala is the tenth country with the highest level of exposure to disaster worldwide. Globally, it ranks 28th regarding vulnerability according to the 2021 INFORM’s risk index and 62nd in the Global Climate Risk Index 2021.
In 2020, Guatemala faced a record-breaking and devastating hurricane season with extreme rainfall, catastrophic winds, and deadly landslides, from which the country has not yet recovered. Unfortunately, recurrent extreme weather events, such as Hurricane Julia that hit Central America in early October 2022, progressively but deeply eroded a weak health infrastructure and local health systems.
