Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

Le cancer du sein est le cancer le plus courant dans le monde et la première cause de mortalité imputable cette maladie chez les femmes. Il touche de façon disproportionnée les pays à revenu faible et intermédiaire. L’Initiative mondiale contre le cancer du sein met tout en œuvre pour faire... reculer la mortalité due à cette maladie de 2,5 pour cent par an, ce qui, en vingt ans, pourrait sauver 2,5 millions de vies. Cet ensemble de mesures techniques fondamentales a pour objet de définir les grandes lignes d’une voie qui mènerait à des améliorations progressives et pérennes, adaptées aux besoins spécifiques des pays et reposant sur trois stratégies et objectifs clés : promotion de la santé à l’appui d’une détection précoce, diagnostic en temps voulu et prise en charge globale du cancer du sein. Le présent document propose un cadre commun associant les décideurs politiques, les parties prenantes, le milieu hospitalier, les gestionnaires de programmes et la société civile à une démarche systématique fondée sur des données probantes susceptible de faciliter le renforcement des systèmes de santé et de diminuer les inégalités touchant à la santé des femmes tout au long de leur vie.

Recent United Nations Conferences of the Parties (COPs) have demonstrated that health professionals are
playing an increasingly prominent role in calling for rapid action to address the climate crisis.
As of 12 December 2022, over 645 million people worldwide have been diagnosed with COVID-19, with over 6.6 million deaths (4).
The Omicron variant, which emerged in late November 2021, and its subvariants, are now the dominant circulating viruses, contributing to the ongoing surge in several countr...ies (4). Vaccination has substantially reduced case numbers and hospitalizations in many countries,but limitations in global access to vaccines mean that many populations, including those in low- and middle-income countries, remain vulnerable. Even in vaccinated individuals, uncertainties remain about duration of protection and efficacy, and the degree of crossprotection with new variants.
There remains a need for more effective treatment and management for those affected by COVID-19. The pandemic – and the
explosion of both research and misinformation – has highlighted the need for trustworthy, accessible and regularly updated living
guidelines to place emerging findings into context and provide clear recommendations for clinical practice

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

services due to decreased income and lockdown
restrictions. The most significant service disruptions
were in maternal and newborn health, vaccination,

It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.

Lack of trained providers capable of identifying which labouring women could benefit from assisted vaginal birth (AVB), and of safely performing the procedure is a major barrier for its use. Education and training are, therefore, considered crucial for building skills and confidence in conducting AV...B and there is evidence that it would be welcomed by healthcare providers. However, acquiring and maintaining AVB skills is a complex task that requires a supportive environment, mentorship, supervision and accountability. As with other practices to manage infrequent procedures and complications, continuous education and on-site supervision are essential to ensure the safe and sustainable use of AVB.
