El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

The United Nations Secretary-General, António Guterres, echoed the concerns of people and organisations around the world when he recently referred to the impact of the COVID-19 pandemic on schooling as a
‘generational catastrophe’.

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

UNFPA implements programmes addressing gender-based violence (GBV) in 153 countries and territories, many of which face humanitarian emergencies. Leading resources used by GBV practitioners include the Inter-Agency Minimum Standards for Gender-Based Violence in Emergencies Programming (the GBViE Min...imum Standards) released in 2019 and the Essential Services Package for Women and Girls Subject to Violence released in 2015. Experiences across UNFPA have shown that GBV practitioners have faced challenges in determining when and how to use these tools and how to adapt different approaches to diverse contexts.

This study has been produced jointly by Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, a federally owned enterprise, implementing development programmes on behalf of the German Government, and CBM, a non-governmental organisation. Accordingly, its aim is to offer guidance to those in bo...th governmental and non-governmental organisations on development cooperation. Given the wide and differing range of implementation procedures, levels of intervention and organisational cultures, it is not a ready-to-be-applied toolbox with concrete blueprints for action. Rather, it raises awareness on core human rights and disability – inclusive principles. It explains and illustrates the implications of applying these principles to development practice. Practitioners can therefore use the guidance to initiate a process of consideration of how to embed these principles within their programmes.

The guide is designed to help disaster managers in national Governments gain basic knowledge of how to use international tools and services. It aims to support the growing disaster response and disaster response preparedness capabilities that exist at national level across Asia and the Pacific.
...
The guide is for national disaster management organizations (NDMOs) and line ministries involved in disaster response and disaster response preparedness. It is also a reference document for representatives of intergovernmental organizations, civilsociety actors and disaster-affected people.
The guide concentrates on key tools and services that can be helpful to disaster managers during the response and response preparedness phases of the disaster programme cycle.

Not long ago, on the occasion of the 100th anniversary of the discovery of Chagas disease, several campaigns denounced the scant progress has been made in diffrent spheres- medical, scientific and politcal- but major challanges still remain. This is an appropriate time to celebrate what has been ach...ieved and to take the next step.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

In response to a call by the United Nations Secretary-General and the Governments of Guinea, Liberia and Sierra Leone, an international team conducted an Ebola Recovery Assessment.The aim was to contribute towards laying the foundation for short-, medium- and long-term recovery while the medical eme...rgency response continues to tackle the epidemic.
This summary report is based on a full report as well as three detailed reports submitted to each of the three governments as contributions to their national recovery planning processes.

La Convención de los Derechos del Niño (Convención) de las Naciones
Unidas (ONU) y documentos relacionados tienen el potencial de mejorar
enormemente varias dimensiones de la vida de los niños (definidos como
desde el nacimiento hasta la los 18 años, dependiendo de la cultura), ofreciendo
p...rotección ante el abuso, fortaleciendo la relación de los niños con sus familias
y garantizando la realización del potencial individual. Estos documentos van
más allá de implicaciones para los gobiernos y deben considerarse en relación
con todas las actividades profesionales relacionadas con la vida de los niños,
incluyendo la práctica clínica, la investigación, la participación y educación.
