Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

Recommended actions at international and national levels
Children in Kabwe are especially at risk because they are more likely to ingest lead dust when playing in the soil, their brains and bodies are still developing, and they absorb four to five times as much lead as adults. The consequences for children who are exposed to high levels of lead and are no...t treated include reading and learning barriers or disabilities; behavioral problems; impaired growth; anemia; brain, liver, kidney, nerve, and stomach damage; coma and convulsions; and death. After prolonged exposure, the effects are irreversible. Lead also increases the risk of miscarriage and can be transmitted through both the placenta and breastmilk.

The Access to Controlled Medications Programme identified the development of treatment guidelines that cover the treatment of all types of pain as one of the core areas of focus for improving access to opioid analgesics. Such guidelines are interesting both for health-care professionals and policy-...makers. They are also important in improving access to controlled medicines for determining when those opioid medicines and when non-opioid medicines are preferred.
Based on a Delphi study, WHO planned the development of three treatment guidelines, covering chronic pain in children, chronic pain in adults and acute pain.

WHO/Europe has launched a new guide, providing support to countries on how to apply behavioural and cultural insights (BCI) for health. It presents a simple step-wise approach, complemented by a rich collection of detailed considerations, tools and exercises. The guide is the first of its kind, spec...ifically developed for use by public health professionals developing policies, services and communications informed by BCI across health topics.
Some of the most persistent public health challenges involve human behaviour. Using a BCI lens means that health policies, services and communications can be tailored to the needs and circumstances of people and communities, and thereby help combat these challenges. The new Tailoring Health Programmes (THP) guide describes how this can be done.
Building on several topic-specific guides that focused on applying BCI to routine and influenza vaccination and tackling antimicrobial resistance, as well as external evaluations and a rigorous peer-review process, this guide is the result of over a decade of work by WHO/Europe. The THP approach has already been adopted in over 20 countries and has received positive feedback from public health agencies.
“This guide is the culmination of a decade of work involving many colleagues at country, regional and global levels. The guide is our “BCI bible”, guiding our work with and in countries to help tackle persistent health challenges,” said Katrine Bach Habersaat, Regional Advisor for BCI at WHO/Europe.
Karina Godoy, Senior Analyst and National Focal Point for Behavioural Insights at the Public Health Agency of Sweden, who is employing the approach described in the guide across several health projects, comments: “The THP guide is easy to use and at the same time provides detailed guidance and inspiration where needed. We have decided to translate the document into Swedish and use the approach widely”.

Global Education Review, 3(3).4-27
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).
