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).

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.

Cardiovascular disease, heart disease, and coronary heart disease may sound similar but they are not one in the same. This fact sheet will help you understand how these conditions differ.
This page presents all our content related to COVID-19. It aims to: 1. Help people who want to understand or work on COVID-19 right now. 2. Help people who are considering biosecurity careers longer term.
This page will focus on leveraged opportunities in research, policy, technology and startups. ...Many people will find their best opportunities to help in their local community – supporting health workers, driving delivery vans, helping friends and family, looking after neighbours, and so on. If you already play a role in providing essential services it’s likely that working hard at your day job, while making efforts to avoid spreading the virus, is one of the most valuable things you can do.

Malattie infettive come il COVID-19 possono implicare una interruzione delle attività negli ambienti in cui i bambini crescono e si sviluppano. Tali interruzioni, che coinvolgono famiglie, amicizie, routine quotidiane e la comunità nel suo senso più ampio, possono avere conseguenze negative sul b...enessere, lo sviluppo e la protezione dei bambini.

Enfermedades infecciosas como el COVID-19 pueden alterar los entornos donde niños, niñas y adolescentes crecen y se desarrollan. Cambios que desestabilizan a la familia, las amistades, la rutina diaria y la comunidad en general o pueden tener consecuencias negativas en el bienestar, el desarrollo ...y la protección de la niñez y adolescencia. Además, las mismas medidas emprendidas para prevenir y controlar la transmisión del COVID-19 pueden conllevar riesgos de protección en niños, niñas y adolescentes. Las medidas de cuarentena y aislamiento en el hogar, las instalaciones o zonas concretas pueden afectar negativamente a los niños, las niñas y sus familias.
Este documento aspira a brindar apoyo a los profesionales de la protección de la niñez y adolescencia para que puedan responder de manera más eficiente a los riesgos de protección durante la pandemia del COVID-19. En la 1ª Parte se presentan los posibles riesgos en materia de protección de la niñez y adolescencia que puede generar el COVID-19, mientras que en la 2ª Parte se ofrecen opciones programáticas que se adhieren a las normas mínimas para la protección de la niñez y adolescencia en la acción humanitaria (NMPI o CPMS, por sus siglas en inglés) de 2019 y la nota orientativa sobre la protección de la niñez y adolescencia durante brotes de enfermedades infecciosas (enlaces en inglés).

Les maladies infectieuses comme le COVID-19 peuvent perturber l’environnement dans lequel les enfants grandissent et se développent. Les bouleversements qui affectent les familles, les relations avec les amis, les routines quotidiennes et l’ensemble de la communauté peuvent avoir des répercus...sions négatives sur le bien-être, le développement et la protection des enfants. En outre, les mesures appliquées pour prévenir et contrôler la propagation du COVID-19 peuvent exposer les enfants à des risques pour leur protection. Les mesures de quarantaine et d’isolement au domicile ainsi que dans des installations ou des zones spécifiques peuvent affecter de façon négative les enfants et leur famille.
L’objectif du présent document est d’aider les professionnels de la protection de l’enfance à mieux faire face aux risques dans ce domaine lors d’une pandémie de COVID-19. La première partie présente les risques potentiels pour la protection de l’enfance auxquels le COVID-19 peut exposer les enfants. La seconde partie décrit des options programmatiques conformes à l’édition 2019 des Standards minimum de protection de l’enfance dans l’action humanitaire (SMPE) et à la Note d’information : Protection des enfants lors d’épidémies de maladies infectieuses (en anglais).

This is a case-ascertained prospective investigation of all identified health care contacts working in a health care facility in which a laboratory confirmed 2019-nCoV infected patient (see 2.2 Study population) receives care. Note that this study can be done in health care facilities at all 3 level...s of a health system – not just in hospitals. It is intended to provide epidemiological and serologic information which will inform the identification of risk factors 2019-nCoV infection among health care workers.
There are three primary objectives of this investigation among health care workers in a health care setting where a 2019-nCoV infected patient is being cared for:
To better understand the extent of human-to-human transmission among health care workers, by estimating the secondary infection rate1 for health care worker contacts at an individual level.
To characterize the range of clinical presentation of infection and the risk factors for infection among health care workers.
To evaluate effectiveness of infection prevention and control measures among health care workers
To evaluate effectiveness of infection prevention and control programmes at health facility and national level
