Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the South of the United States. It is an important cause of early mortality and morbidity, and it is associated with po...verty and stigma. A third of the cases evolve into chronic cardiomyopathy and gastrointestinal disease. This review proposes strategies to address challenges faced by non-endemic countries

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.

Cutaneous leishmaniasis (CL) is a neglected infectious endemic disease that is transmitted through the bite of a vector insect (sandfly) of the Lutzomyia genus,typical of rural geographical territories, and causes disfiguring skin ulcers and disabilities. It is estimated that CL affects between 600 ...000 and 1 000 000 people a year around the world, mainly in the America s, the Mediterranean basin, the Middle East and Central Asia. Eighteen of the 21 countries that make up the Latin American (LA) region are considered endemic areas for this neglected tropical disease. Colombia is one of the countries that reports the majority of global cases with 6161 in 2020 and has the second highest number of cases in the Americas, after Brazil.

Leishmaniasis is a complex vector-borne disease involving in its transmission several species of protozoan parasites called Leishmania, a wide variety of animal reservoirs and phlebotomine sandflies vectors. Cutaneous Leishmaniasis (CL) is the most common form of the disease, and its clinical manife...stations vary from few papules to multiple ulcers affecting the skin but also the mucous membranes, leaving permanent scars and serious disability. It is a disfiguring and stigmatizing disease that often has a devastating psychosocial and economic impact on the affected resources limited communities.

The burden of diabetes is enormous, positioning it as one of the main challenges facing public health today. Currently, it is estimated that 62 million people are living with diabetes in the Region of the Americas and projections show its prevalence will continue rising over the following years. The... Region shows the highest number of years of healthy life lost (through either disability or premature death) due to diabetes worldwide. The high costs associated with its treatment produce a heavy economic burden. Its complications can seriously affect the quality of life of people living with diabetes, their families, and society and overload health systems. This report shows the latest internationally comparable data on diabetes and its main risk factors by year, country, and sex.

La carga de la diabetes es enorme, posicionándola como uno de los principales desafíos que enfrenta la salud pública en la actualidad. Actualmente, se estima que 62 millones de personas viven con diabetes en la Región de las Américas y las proyecciones muestran que su prevalencia seguirá aumen...tando en los próximos años. La Región muestra el mayor número de años de vida saludable perdidos (ya sea por discapacidad o muerte prematura) debido a la diabetes en todo el mundo. Los altos costes asociados a su tratamiento producen una pesada carga económica. Sus complicaciones pueden afectar seriamente la calidad de vida de las personas que viven con diabetes, sus familias y la sociedad y sobrecargar los sistemas de salud. Este informe muestra los últimos datos comparables internacionalmente sobre la diabetes y sus principales factores de riesgo por año, país y sexo. También incluye un resumen de la respuesta de los sistemas de salud de los países a la diabetes, incluidos planes nacionales, objetivos, vigilancia, directrices y acceso a medicamentos y tecnologías esenciales, y sintetiza información sobre las complicaciones relacionadas con la diabetes y la estrecha relación entre la diabetes y otras patologías, como enfermedades cardiovasculares, tuberculosis y COVID-19.

El presente informe regional sobre la situación de la tuberculosis en las Américas contiene la información correspondiente al 2019, provista por los países de la Región a través del sistema de recolección de datos de TB de la OMS. Esta información ha sido consolidada y analizada a nivel regi...onal. Su objetivo, además de presentar la situación epidemiológica y programática de la TB en las Américas, es sensibilizar, motivar e incentivar a todas las partes involucradas en la prevención y el control de esta enfermedad, para acelerar los esfuerzos hacia su eliminación en la Región y alcanzar las metas de la Estrategia Fin de la TB. En el informe se consignan los logros, pero también las brechas en el trabajo que se realiza en aspectos de diagnóstico, tratamiento, comorbilidades, poblaciones vulnerables, factores de riesgo y financiación, entre otros asuntos. A partir de la información presentada, se brindan unas recomendaciones concretas para seguir avanzando.

COVID-19 Vaccine Introduction Readiness Assessment Tool (VIRAT2), developed by WHO-PAHO, UNICEF, World Bank, Gavi, and other partners is a tool to help prepare countries for the introduction a COVID-19 vaccine.
It provides a roadmap for introduction and a structured framework for countries to self-...monitor their readiness progress against key milestones. It includes an excel template for Ministries of Health to complete with support from partners and PAHO Country Offices.
The VIRAT dashboard helps countries highlight the critical activities and technical areas that should be initiated, continued, or strengthened. Also, it allows PAHO and partners to identify areas where support may be needed and identify alternative forms to mobilize resources.
