Según las estimaciones, en las Américas hay entre 6 y 8 millones de personas con infección por T. cruzi, con aproximadamente 30 000 casos nuevos por año por transmisión vectorial, y 8000 casos nuevos anuales por transmisión congénita. Es decir, cerca de 65 millones de personas viven en la Reg...ión con el riesgo de contraer la infección. Además, durante cualquiera de las fases de esta parasitosis, las personas con la infección pueden sufrir algún grado de inmunosupresión, bien sea por una infección, una neoplasia o por un tratamiento farmacológico. En este decálogo se exponen los conceptos más importantes para tener en cuenta frente a la coexistencia de inmunosupresión y la infección por el T. cruzi.

The menu was developed using the WHO-CHOICE methodology to prepare and update, as appropriate, WHO estimates of the cost-effectiveness of a range of mental health interventions, in line with the development of Appendix 3 to the global action plan for the prevention and control of noncommunicable dis...eases 2013–2020.
WHO-CHOICE is a programme that helps countries to identify priorities based on health impact and cost-effectiveness. It can be applied to a wide range of strategies relevant to policies affecting health outcomes. All options are compared to a common comparator, a null scenario in which the impacts of currently implemented interventions are removed, thereby enabling comparison of interventions across geographical areas and aspects of health.

Almost half (46%) of the world’s 1.7 million children living with HIV were not on treatment in 2020 and 150 000 children were newly infected with HIV, four times more than the 2020 target of 40 000
2021 UNAIDS Global AIDS Update. UNAIDS report shows that people living with HIV face a double jeopardy, HIV and COVID-19, while key populations and children continue to be left behind in access to HIV services
15 July 2021. This report describes the demographics, clinical presentation, clinical outcomes, and risk factors among people living with HIV (PLHIV) who have been hospitalized for suspected or confirmed COVID-19.
The specific objectives of the analysis were to:
describe the clinical char...acteristics and outcomes of PLHIV hospitalized for COVID-19
assess whether PLHIV hospitalized with COVID-19 were at increased risk of presenting with severe or critical illness at admission and were at increased risk of in-hospital death compared to individuals not infected with HIV
assess risk factors associated with severe or critical illness at hospital admission and of in-hospital death among PLHIV hospitalized for COVID-19.

La OMS ha elaborado una definición de caso clínico de la afección posterior a la COVID-19 mediante la metodología Delphi que incluye 12 dominios, disponible para su uso en todos los entornos. Esta primera versión fue elaborada por pacientes, investigadores y otras personas, en representación d...e todas las regiones de la OMS, en el entendimiento de que la definición puede cambiar a medida que surjan nuevas pruebas y siga evolucionando nuestra comprensión de las consecuencias de la COVID-19.
La afección posterior a la COVID-19 se produce en personas con antecedentes de infección probable o confirmada por el CoV-2 del SRAS, normalmente a los 3 meses de la aparición de la COVID-19 con síntomas y que duran al menos 2 meses y no pueden explicarse por un diagnóstico alternativo. Los síntomas más comunes son la fatiga, la dificultad respiratoria y la disfunción cognitiva, pero también otros, y generalmente tienen un impacto en el funcionamiento diario. Los síntomas pueden ser de nueva aparición tras la recuperación inicial de un episodio agudo de COVID-19 o persistir desde la enfermedad inicial. Los síntomas también pueden fluctuar o recaer con el tiempo.

Modelling the health impacts of disruptions to essential health services during COVID-19 Module 1
Several epidemiological models have been created to assess the potential impact of disruptions to essential health services caused by COVID-19 on morbidity and mortality from conditions other than COVI...D-19 illness. This guide presents models that have been used to assess these indirect impacts. The effects have been studied in various settings, using a variety of models.
The guide is intended for people who need to understand what the models say, their construction and their underlying assumptions, or need to use models and their outcomes for planning and programme development and to support policy decisions for a country or region.

Interium guidance, 25 June 2021Timely and accurate diagnostic testing is an essential tool in preventing and controlling the spread of COVID-19. This document describes recommendations for national testing strategies and the use of PCR and rapid antigen tests in different transmission scenarios of t...he COVID-19 outbreak, including how testing might be rationalized in low resource settings. All testing should be followed by a strong public health response including isolating those who test positive and providing them care, contact tracing and quarantine of contacts.

People-centered approaches that help communities maintain protective behaviours and follow guidelines set out by public health and government agencies are more important than ever. The evidence is clear, communities play a role in preventing and controlling epidemics and they are best able to take a...ction and slow or stop the spread of disease when properly engaged and empowered. This toolbox in 2 parts offers best practice approaches to community engagement with families. Promoting individual and joint responsibilities for the safety of the family, this toolbox aims to bring families and households together to manage shared risks and agree to safe behaviours critical for their safety and the safety of their community.
