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).

Advances in the treatment of pediatric cancer have made it possible to expand initiatives beyond cure and cover aspects such as early detection, continuity of treatment and reduction in toxicity. All this has paved the way for a more comprehensive vision of patient care, which means better chances o...f healing and a fuller life - objectives of the World Initiative against Childhood Cancer. Within this comprehensive care, psychosocial care includes the social, psychological, spiritual and functional dimensions of the disease process of patients. This series includes guidelines and standards based on evidence that guarantee the quality of said care. The standards are the result of discussion and review by different professionals from Latin America and the Caribbean. Module 1 focuses on psychosocial evaluation as a strategy to support the objectives of the World Initiative against Childhood Cancer, and as a tool for health professionals to gather the necessary information to offer these patients a comprehensive approach focused on well-being, adaptation to the disease process, and adherence to treatment.

The new treatment recommendations that extend the 2018 treat all recommendation for adults with chronic HCV infection to include adolescents and children down to 3 years, and to align the existing recommended pangenotypic direct-acting antiviral (DAA) regimens (SOF/DCV, SOF/VEL and G/P) for adults, ...to those for adolescents and children. This alignment is expected to simplify procurement, promote access to treatment among children in low- and middle-income countries and contribute to global efforts to eliminate the disease

Sexual exploitation, sexual abuse and sexual harassment (SEAH) violate the rights and wellbeing of the people we serve and the people with whom we serve. Such behaviours are directly in opposition to WHO’s values and our abiding responsibility to do no harm. WHO uses the umbrella term “sexual mi...sconduct” to encompass the full spectrum of prohibited and unwanted behaviour of a sexual nature (including rape and sexual assault) as described in WHO’s 2023 Policy for preventing and addressing sexual misconduct (1). This is because all such acts are prohibited – whether perpetrated by WHO’s own personnel or by implementing partners – and therefore constitute misconduct. The term sexual misconduct is also easier to communicate and translate, as
victims and survivors do not always understand the complicated acronyms and definitions used by the United Nations (UN) and the humanitarian sector. However, we use the terms sexual misconduct and SEAH interchangeably as required when we interact with UN and other stakeholders.

Recent efforts to fight malaria in the Greater Mekong Subregion (GMS) have yielded impressive results. According to the latest WHO estimates, the six GMS countries cut their malaria case incidence by an estimated 54% between 2012 and 2015. Malaria death rates fell by 84% over the same period.
I...n May 2015, GMS Ministers of Health adopted the WHO Strategy for malaria elimination in the Greater Mekong Subregion 2015-2030. Urging immediate action, the plan aims to eliminate P. falciparum malaria from the subregion by 2025 and all species of human malaria by 2030.

This technical report contains the results from the FEEDcities Project – Eastern Europe and Central Asia, a cross-sectional survey of the local urban food environment conducted in Chișinău, Republic of Moldova between June and August 2016. It characterizes the vending sites, the food offered and... the nutritional composition of both industrial and homemade street foods. It also describes the nutritional composition of foods sold in supermarkets and fast-food outlets.
The study was conducted within a bilateral partnership between the World Health Organization and the Institute of Public Health of the University of Porto, in collaboration with the Faculty of Medicine, the Faculty of Nutrition and Food Sciences and the Faculty of Pharmacy of the University of Porto (WHO registration 2015/591370 and 2017/698514).

Expert opinion of the European Tuberculosis Laboratory Initiative core group members for the WHO European Region.
This checklist is for any organization or person supporting the routine use of evidence in
the process of policy-making. Evidence-informed policy-making (EIPM) is essential for achieving the Sustainable Development Goals (SDGs) and universal health coverage (UHC). Its importance is emphasized in WH...O’s Thirteenth General Programme of
Work 2019–2023 (GPW13). This checklist was developed by the WHO Secretariat of Evidence-Informed Policy Network (EVIPNet) to assist its Member countries in institutionalizing EIPM. Government agencies (i.e. the staff of the Ministry of Health),
knowledge intermediaries and researchers focused on strengthening EIPM will find in this checklist some key steps and tools to help their work. While the health sector is a key target group for EVIPNet, this tool can be applied by stakeholders from
different social sectors
