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.

This document updates the earlier version published in April 2020. In recent weeks, information on the potential use of chloroquine or hydroxychloroquine for the treatment of people with COVID-19 has been disseminated in academic journals and public media. Although there are now ongoing clinical tri...als testing the efficacy and safety of several medicines for COVID-19, as of the date of this document, there is a lack of quality evidence to demonstrate chloroquine and/or hydroxychloroquine are effective in the treatment of COVID-19. Evidence is recently emerging via small studies with sub-optimal methodologies that are conflicting.

There is no secret to our procedure: the daily scanning of the literature helps us to stay afloat in the never-ending waves of new publications about SARS-CoV-2 and COVID-19. Many papers discussed in the Top 10 will eventually make it into subsequent editions of COVID Reference.
Это руководство является частью серии, созданной для повышения качества лечения тяжело больных детей в медицинских учреждениях. Оно направлено на увеличение дост...упности и адекватности оксигенотерапии, в том числе в условиях ограниченности ресурсов.
Руководство ссылается на необходимость надлежащей диагностики гипоксемии и использования пульсоксиметрии, аппаратов доставки кислорода и наблюдения за пациентами,
получающими оксигенотерапию. Кроме того, руководство выступает за практическое применение пульсоксиметрии, а также концентраторов кислорода и кислородных баллонов.

There is no secret to our procedure: the daily scanning of the literature helps us to stay afloat in the never-ending waves of new publications about SARS-CoV-2 and COVID-19. Many papers discussed in the Top 10 will eventually make it into subsequent editions of COVID Reference.
As of 31 October 2020 This is the tenth edition of this summary of rapid systematic reviews, which includes the results of a rapid systematic review of currently available literature. More than 200 therapeutic options or their combinations are being investigated in more than 1,700 clinical trials. I...n this review, 46 therapeutic options are examined. The Pan American Health Organization (PAHO) is continually monitoring ongoing research on any possible therapeutic options. As evidence emerges, then PAHO will immediately assess and update its position, and particularly as it applies to any special sub-group populations such as children, expectant mothers, those with immune conditions, etc.

The consolidated guidelines are complemented by an operational handbook which is designed to assist with implementation of the WHO recommendations by Member States, technical partners and others who are involved in the management of patients with DR-TB. The WHO Operational Handbook on Tuberculosis, ...Module 4: Treatment - Drug-Resistant Tuberculosis Treatment provides practical guidance on how to put in place the recommendations at the scale needed to achieve national and global impact.
The operational handbook provides practical information and tools that complement the recommendations in the guidelines. The strategies described in the operational handbook are based on the latest WHO recommendations which were formulated by Guideline Development Groups using the GRADE approach. In many cases however, the recommendations in their current form lacked sufficient clinical and programmatic detail, which is important for implementation. This operational handbook complements the guidelines with practical advice based on best practices and knowledge from the fields such as pharmacokinetics, pharmacodynamics, microbiology, pharmacovigilance and clinical and programmatic management.
