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).

Hand hygiene is vital for safe health care delivery, yet practices at the point of care remain suboptimal worldwide. A comprehensive research agenda is therefore necessary to improve our understanding of factors influencing hand hygiene behaviour and to strengthen appropriate interventions. This age...nda will provide insightful ideas for researchers to focus their projects and funding proposals and will direct donors towards the areas of hand hygiene evidence that require urgent support and innovation. It will also guide decision-makers and stakeholders at the national and international level and support country efforts in updating and strengthening hand hygiene promotion programmes. Global collaboration and investment in hand hygiene research remain essential to promote safe and effective care worldwide.

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.

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.

Vaccines are powerful weapons in the fight against pandemic viruses as shown by responses to both the 2009 H1N1 influenza and the COVID-19 pandemics. However, planning for accessing, allocating and deploying vaccines in a pandemic situation is a complex endeavour, beset with multiple challenges at a...ll levels – local, regional and global. The World Health Organization (WHO) and its partners have prepared this revised guidance document to assist countries update their national deployment and vaccination plans (NDVPs) by leveraging global learnings from past pandemic responses, including the recent COVID-19 vaccination effort. The development and testing of a NDVP would not only advance pandemic preparedness efforts but would also have benefits in terms of increasing national capabilities to manage other health emergencies which require emergency vaccination campaigns.

The objective of the 2022 Compendium is to compile and highlight emerging innovative health technologies for low-resource settings. It presents a snapshot of technologies that are solutions to an unmet medical/health technology need or are likely to improve health outcomes and the quality of life. H...ealth technologies in the Compendium underwent WHO evidence-based assessments focused on the life cycle of health technology innovations for low-resource settings.

This course provides information on what facilities should be doing to be prepared to respond to a case of an emerging respiratory virus such as the novel coronavirus, how to identify a case once it occurs, and how to properly implement IPC measures to ensure there is no further transmission to HCW ...or to other patients and others in the healthcare facility. This course has been updated in January 2022 and highlights the latest WHO guidance to date. Please note that our guidance is continuously being updated and the other language versions of the course will gradually be updated too.
This training is intended for healthcare workers and public health professionals, as it is focused on infection prevention and control.
This course is also available in the following languages:
русский - 日本語 - français - Bahasa Indonesia - Español - Português - Italiano - српски језик - 中文 - македонски јазик - Türkçe - język polski - Tiếng Việt - العربية - Nederlands - Tetun - বাংলা - فارسي - Soomaaliga

Health care waste can be difficult to treat and dispose of safely. The environmental and health impacts of waste put extra pressure on resources. Therefore, it is important to try and reduce the quantities of waste wherever possible. Ensure waste is segregated properly at the point of disposal. It i...s cheaper and easier to manage general waste through a municipal waste system than infectious or sharps waste which needs treatment before final disposal. Organic general wastes like food and paper can be composted rather than being wasted. Non- hazardous general waste may also be sorted for recycling.

Are you aware of the medical waste generated during the pandemic? How does it impact your health and what can you do to reduce it? WHO’s Dr Margaret Montgomery explains in Science in 5.
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.
