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).

Zimbabwe has, over the years, grappled with the repercussions of the climate crisis, which have led to erratic rainfall patterns characterized by either severe floods or prolonged periods of drought. The nation has experienced a concerning trend of numerous regions reporting rainfall levels below th...e usual during what should be "normal" years. The upcoming El Niño event forecasted for 2023-2024, which is associated with drier-than-average rainfall, is poised to exacerbate this predicament. It is expected to intensify aridity, significantly impacting food and animal production across many areas, including those typically classified as "dry regions."

Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

This working draft develops guidance on conducting effective evaluations of conflict prevention and peacebuilding work. The current working draft will be used for a one year application phase through 2008. It is the result of an ongoing collaborative project by the OECD DAC Networks on Development E...valuation and on Conflict, Peace and Development Co-operation (CPDC). The two Networks began this collaboration in 2005, responding to the need expressed by CPDC members for greater clarity regarding techniques and issues of evaluation in their field. An assessment of past conflict and peace evaluations and a study of current practices were undertaken in 2006 and identified a need for further guidance.

Pneumonia and diarrhoea account for 23% of under-five mortality and were responsible for an estimated 1.17 million deaths in children under five globally. Furthermore, pneumonia and diarrhoea were responsible for 18% of mortality in children 5–9 years of age, resulting in an estimated 86 000 preve...ntable deaths globally in 2021. Existing World Health Organization (WHO) guidance on the clinical management of pneumonia and diarrhoea has mainly focused on children less than 5 years of age.

Front. Med., 27 November 2020 | https://doi.org/10.3389/fmed.2020.594728. The Checklist included eight actions for implementing rural pathways in LMICs: establishing community needs; policies and partners; exploring existing workers and scope; selecting health workers; education and training; workin...g conditions for recruitment and retention; accreditation and recognition of workers; professional support/up-skilling and; monitoring and evaluation. For each action, a summary of LMICs-specific evidence and prompts was developed to stimulate reflection and learning. To support implementation, rural pathways exemplars from different WHO regions were also compiled. Field-testing showed the Checklist is fit for purpose to guide holistic planning and benchmarking of rural pathways, irrespective of LMICs, stakeholder, or health worker type.
