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).

Children continue to be exposed to powerful food marketing, which predominantly promotes foods high in saturated fatty acids, trans-fatty acids, free sugars and/or sodium and uses a wide variety of marketing strategies that are likely to appeal to children. Food marketing has a harmful impact on chi...ldren’s food choice and their dietary intake, affects their purchase requests to adults for marketed foods and influences the development of their norms about food consumption. Food marketing is also increasingly recognized as a children’s rights concern, given its negative impact on several of the rights enshrined in the United Nations Convention on the Rights of the Child.This WHO guideline provides Member States with recommendations and implementation considerations on policies to protect children from the harmful impact of food marketing, based on evidence specific to children and to the context of food marketing. Guidelines on other policies to improve the food environment are currently under development.

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline... is available both online and PDF.
This version of the living guideline (version 6.0) includes fifteen statements on IPC measures in health-care settings (screening and patient placement, ventilation, physical barriers, environmental cleaning, waste management, amongst others) as well as one statement on mask fit in the community context.

The goal of this addendum is to help management and staff
minimize the risk of TB transmission at facilities in resource limited settings in which a.) HIV-infected persons receive diagnosis, care, treatment,
and/or support, and b.) there is a high prevalence of HIV infection, both known
and... undiagnosed, in settings such as prisons, jails, other
detention centers, and drug rehabilitation centers.

22 April 2022, This document provides updated interim recommendations on the use of masks by health workers providing care to patients with suspected or confirmed COVID-19. This update is prompted by new evidence around mask use and COVID-19 transmission, as well as the emergence of variants of conc...ern including Omicron. Masks continue to be a critical tool to prevent the spread of COVID-19. These interim guidelines supersede the recommendations provided in the WHO recommendations on mask use by health workers, in light of the Omicron variant of concern published on 22 December 2022.
WHO continually evaluates the emerging evidence and will review these interim recommendations within two months and issue new guidance as needed.

A guide for Regional Workshop and Hospital Technicians
The Panel recommendations on initial combination regimens for the antiretroviral therapy (ART)-naive, HIV-infected patients.
The Ministry of Health together with its partners realizes that efficient and effective
delivery of clinical care is highly dependent on the availability of appropriately
upgraded environment, which is in well facilitated space. Such facilities and utilities
should always be properly designed, bu...ilt, and maintained, so as to ensure efficient
treatment in clean and safe from infection.
The main challenges in achieving this include the lack of, appropriate holistic and
futuristic management plans, human resource for facility/utility management and
maintenance, adequate budget funds for renovation/maintenance activities at all
levels which means daily and long-term of facility maintenance plans and executions.
It is hoped that the guidelines will help to standardise
design of medical facilities and utilities country wide and result in efficient and
effective establishment of these life-saving function
