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.

В этом Кратком руководстве рассматриваются фактические данные и даются рекомендации по использованию
методов визуализации органов грудной клетки при оказании н...еотложной помощи взрослым пациентам
с подозреваемым, вероятным или подтвержденным диагнозом COVID-19, включая такие методы, как
рентгенография органов грудной клетки, компьютерная томография (КТ) и ультразвуковое исследование
легких. Оно должно стать практическим руководством для медицинских работников, занятых оказанием
помощи при COVID-19, начиная с этапа поступления пациента в медицинское учреждение и заканчивая
его выпиской из стационара. Это руководство охватывает вопросы ведения пациентов с заболеванием
различной степени тяжести – от бессимптомных форм до критических состояний.

The growing understanding of how sequence information can contribute to improved public health is driving global investments in sequencing facilities and programmes. The falling cost and complexity of generating GSD provides opportunities for expanding sequencing capacity; however, challenges to wid...espread implementation remain. This document provides policy-makers and stakeholders with guidance on how to maximize the public health benefit of SARS-CoV-2 genomic sequencing activities in the short and long term as the pandemic continues to unfold. Practical considerations for the implementation of a virus genomic sequencing programme and an overview of the public health objectives of genomic sequencing are covered. This guidance focuses on SARS-CoV-2 but is applicable to other pathogens of public health concern.

Interim guidance 2 march 2021
Current use of drugs to prevent COVID-19 is variable, reflecting large-scale uncertainty. Numerous randomized trials of many different drugs are underway to inform practice. This first version of the Drugs to prevent COVID-19: A WHO living guideline contains new inform...ation and a recommendation on hydroxychloroquine. It follows the publication of six trials synthesized in a living network meta-analysis (NMA).

Working Paper 589 July 2021T
Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.

Key questions
What is already known?
Critical illness is common throughout the world and COVID-19 has caused a global surge of critically ill patients.
There are large gaps in the quality of care for critically ill patients, especially in low-staffed and low-resourced settings, and mortal...ity rates are high.
Essential Emergency and Critical Care (EECC) is the effective lifesaving care of low-cost and low-complexity that all critically ill patients should receive in all wards in all hospitals in the world.
What are the new findings?
The clinical processes that comprise EECC and the essential care of critically ill patients with COVID-19 have been specified in a large consensus among clinical experts worldwide.
The resource requirements for hospitals to be ready to provide this care has been described.
What do the new findings imply?
The findings can be used across medical specialties in hospitals worldwide to prioritise and implement essential care for reducing preventable deaths.
Inclusion of the EEEC processes could increase the impact of pandemic preparedness and response programmes and policies for health systems strengthening.

Resumen ejecutivo guía de práctica clínica manejo de la infección por Sars-CoV 2
The United Nations Children's Fund (UNICEF), the International Organization for Migration (IOM), Georgetown University, and the United Nations University have today launched new guidelines to provide the first-ever global policy framework that will help protect, include, and empower children on the ...move in the context of climate change.
The Guiding Principles for Children on the Move in the Context of Climate Change provides a set of 9 principles that address the unique and layered vulnerabilities of children on the move both internally and across borders as a result of the adverse impacts of climate change. Currently, most child-related migration policies do not consider climate and environmental factors, while most climate change policies overlook the unique needs of children.
The guidelines note that climate change is intersecting with existing environmental, social, political, economic, and demographic conditions contributing to people’s decisions to move. In 2020 alone, nearly 10 million children were displaced in the aftermath of weather-related shocks. With around one billion children – nearly half of the world’s 2.2 billion children – living in 33 countries at high risk of the impacts of climate change, millions more children could be on the move in the coming years.
Developed in collaboration with young climate and migration activists, academics, experts, policymakers, practitioners, and UN agencies, the guiding principles are based on the globally ratified Convention on the Rights of the Child and are further informed by existing operational guidelines and frameworks.
Recommendations for safeguarding the rights and well-being of children regardless of their location or migration status.
The guiding principles provide national and local governments, international organizations and civil society groups with a foundation to build policies that protect children’s rights. The organizations and institutions are calling on governments, local and regional actors, international organizations, and civil society groups to embrace the guiding principles to help protect, include, and empower children on the move in the context of climate change.
