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).

Integrating the prevention and control of noncommunicable diseases in HIV/AIDS, tuberculosis, and sexual and reproductive health programmes: implementation guidance
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 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

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 WHO document "Integrating the prevention and control of noncommunicable diseases in HIV/AIDS, tuberculosis, and sexual and reproductive health programmes: implementation guidance" provides a framework for integrating noncommunicable diseases (NCDs) into existing health programs for HIV/AIDS, tub...erculosis (TB), and sexual and reproductive health (SRH). It emphasizes the importance of a people-centered approach to enhance healthcare accessibility and efficiency, especially in low-resource settings. The document outlines strategies for strengthening policy, financing, capacity building, and health system infrastructure. It offers actionable steps, tools, and case studies to support countries in reducing the burden of NCDs through integrated, holistic care within primary health services.

Epidemiology, Control, and Financing
The report “Dementia: a public health priority” has been jointly developed by WHO and Alzheimer's Disease International. The purpose of this report is to raise awareness of dementia as a public health priority, to articulate a public health approach and to advocate for action at international a...nd national levels.
Dementia is a syndrome that affects memory, thinking, behaviour and ability to perform everyday activities. The number of people living with dementia worldwide is currently estimated at 35.6 million. This number will double by 2030 and more than triple by 2050. Dementia is overwhelming not only for the people who have it, but also for their caregivers and families. There is lack of awareness and understanding of dementia in most countries, resulting in stigmatization, barriers to diagnosis and care, and impacting caregivers, families and societies physically, psychologically and economically.

The WHO COVID-19 Essential Supplies Forecasting Tool (COVID-19-ESFT) is meant to help countries forecast essential supplies for their COVID-19 response including personal protective equipment (e.g., masks and gloves), biomedical equipment for case management (e.g., ventilators and oxygen concentrato...rs), diagnostic reagents and equipment, essential drugs for supportive care, and consumable medical supplies.
The tool is best suited for estimating essential supply needs over a short time period (12 weeks or fewer) but can be used for longer.
COVID-19-ESFT does not quantify or account for resources already available locally or those pending delivery. When using the ESFT to inform procurement, we recommend factoring in resources already available locally and only including the additional resources required in the forecast.
This tool is updated regularly so users should monitor the website for the latest release version.

Burns are a global public health problem, accounting for close to 200,000 deaths annually. The majority of these occur in low- and middle-income countries, where a number of constraints complicate the public health task of addressing burns. While the primary prevention of burns in low- and middle-in...come countries is a pressing need, the World Health Organization (WHO) also actively encourages further development of burn-care systems, including the training of health-care providers in the appropriate triage and management of people with burns.

The data presented here reveal that, despite advances in national responses, diabetes continues to expand, and our response remains insufficient. This report aims to draw attention to the urgent need to strengthen efforts to prevent, diagnose, and control diabetes in the Region of the Americas.
