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).

Many of the countries that faced cholera outbreaks in 2022 were badly affected by extreme weather events.
As the climate emergency worsens, human displacement will intensify, along with droughts and flooding – all
conditions that give rise to cholera outbreaks. Unless we invest in systems that b...uild preparedness and

Children without access to safe water are more likely to die in infancy -- and throughout childhood -- from diseases caused by
water-borne bacteria, to which their small bodies are more vulnerable.
An estimated 1.3 billion people globally experience significant disability. This figure has grown over the last decade and will continue to rise due to demographic and epidemiological changes. In 2022, the World Health Organization launched the Global report on health equity for persons with disabil...ities. This report demonstrated that many persons with disabilities are still being left behind. Experiencing persistent health inequities, persons with disabilities die earlier, they have poorer health and functioning, and they are more affected by health emergencies than the general population. These differences are largely associated with unjust factors both inside and beyond the health sector and are avoidable. The Global Report called upon Member States to take actions to make health sector more inclusive for persons with disabilities through the primary health care approach. This will be essential for countries to make health coverage truly universal and to progress towards other health-related targets in the sustainable development goals.

Declarations of interests were collected from all external contributors and assessed for any conflicts of interest. Summaries of the reported interests can be found on the SAGE meeting website and SAGE Covid-19 Working Group webpage. This guidance should be considered along with the broader COVID-...19 policy advice to WHO member states and in particular the advice on how to reach the COVID-19 vaccination targets.

The Look Back Study (LBS) focuses on the water and sanitation and hygiene (WASH) component of the project but some additional information was collected along side the WASH data. This data has been compared to the baseline survey data that was reported at start of the project (see tables in annex D t...o this report).

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

This Urban Flood Risk Handbook: Assessing Risk and Identifying Interventions is a roadmap for conducting an urban flood risk assessment in any city in the world. It includes practical guidance for a flood risk assessment project, covering the key hazard and risk modeling stages as well as the evalua...tion of different flood-mitigating infrastructure intervention options and management of the project. The Handbook has been developed based on lessons learned from implementing urban flood risk assessments around the world in a diversity of contexts. It is intended for a wide variety of practitioners: project managers, city officials, and anyone else interested in conducting a strategic study of a city's flood risk and developing potential solutions for it. We expect this Handbook tocontribute to the understanding of urban flood risk, make this specialized knowledge more accessible to a wider public, and support the process of building cities that are not only capable of withstanding floods but also provide safe, inclusive, and sustainable environments for all their residents.

Several diagnostic criteria of Post-traumatic Stress Disorder (PTSD) are remarkably similar to symptoms reported by individuals with depression, particularly as they manifest as cognitive processing deficits in children. Because of this overlap in profile and the high rate of comorbidity of PTSD and... depression (48% to 69%), pinpointing similarities/differences in cognitive processes related to each of these disorders is essential to accurate diagnosis. This study aims to examine cognitive performance profiles of 23 children who have been victims of PTSD and to compare their results with 23 children with depression and 24 controls.
