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).

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

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.

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.

The report focuses on antibacterial resistance (ABR) in common bacterial pathogens. There is a major gap in knowledge about the magnitude of this problem. Antimicrobial resistance (AMR) threatens the effective revention and treatment of an ever-increasing range of infections caused by bacteria, para...sites, viruses and fungi. This WHO report, produced in collaboration with Member States and other partners, provides for the first time, as accurate a picture as is presently possible of the magnitude of AMR and the current state of surveillance globally. It examines the information on AMR, in particular antibacterial resistance (ABR), at country level worldwide.

In recent years, high prices of pharmaceutical products have posed challenges in high- and low-income countries alike. In many instances, high prices of pharmaceutical products have led to significant financial hardship for individuals and negatively impacted on healthcare systems’ ability to prov...ide population-wide access to essential medicines.
Pharmaceutical pricing policies need to be carefully planned, carried out, and regularly checked and revised according to changing conditions. Strong, well-thought-out policies can guide well-informed and balanced decisions to achieve affordable access to essential health products.
This guideline replaces the 2015 WHO guideline on country pharmaceutical pricing policies, revised to reflect the growing body of literature since the last evidence review in 2010. This update also recognizes country experiences in managing the prices of pharmaceutical products.

These WHO guidelines which were updated in 2018, are valid for any country and suitable to local adaptations, and take account of the strength of available scientific evidence, the cost and resource implications, and patient values and preferences.
The 2018 edition of the guidelines includes the re...vision of the recommendation regarding the use of 80% fraction of inspired oxygen (high FiO2) in surgical patients under general anaesthesia with tracheal intubation and the update of the section on implementation. Between 2017 and 2018, WHO re-assessed the evidence on the use of high FiO2 by updating the systematic review related to the effectiveness of this intervention to reduce SSI and commissioning an independent systematic review on adverse events potentially associated with it. Based on the updated evidence, the GDG decided to revise the strength of the recommendation from strong to conditional.

Psychosoziale Arbeit und psychosoziale Ansätze haben in den letzten 10 Jahren in der internationalen Zusammenarbeit (IZ) immer stärkere Verbreitung gefunden. Es gibt heute kein Krisen- und Konfliktgebiet mehr, wo nicht auch über Trauma und über die emotionale Verfasstheit der Opfer gesprochen wi...rd. Gerade im Zusammenhang mit der Anerkennung der Notwendigkeit genderbewusste Konflikttransformationsprozesse in der Projektarbeit zu unterstützen, sind psychosoziale Konzepte und Methoden immer wichtiger geworden. Dennoch ist bei vielen MitarbeiterInnen der IZ nach wie vor wenig bekannt, was mit psychosozial eigentlich gemeint ist. Während die Literatur über Trauma umfangreich, aber unübersichtlich und widersprüchlich ist, fehlt es nach wie vor an knappen und auf die IZ bezogenen Einführungen in die psychosoziale Thematik.

Formularies are lists of antibiotics that are suggested for certain healthcare settings. In developing a recommended formulary, countries should consider the needs of patients and facilities where they receive care. For example, clinicians in rural or primary health centers may need wide access to f...irst-line antibiotics (e.g., penicillin, ampicillin, TMP-SMX), but last resort antibiotics such as carbapenems or colistin might be limited to tertiary care hospitals. Efforts to create antibiotic formularies may be linked to efforts within countries to create or update essential medicine lists (EML).
