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).

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.

This training module is designed to equip HWs with knowledge and communication skills to build their confidence and support them in their ability to promote acceptance of COVID-19 vaccination among other HWs.
Countries across the world are facing diverse epidemiological situations with varying response
capacities and access to life saving tools. The World Health Organization (WHO) recommends that national authorities continue to apply a risk-based approach when implementing measures related to COVID-19... and international travel while respecting the dignity, human rights and fundamental freedoms of travellers. This approach should consider the risk posed by travel for the importation and exportation of cases in the context of the evolving epidemiology, including the emergence and circulation of virus variants of concern; the expansion of the COVID-19 vaccination roll-out; and lessons learned while responding to the pandemic, including on the early detection and management of cases and the application of public health and social measures.

Les pays du monde entier sont confrontés à des situations épidémiologiques diverses, et disposent de capacités de réaction différentes et d’un accès inégal aux outils permettant de sauver des vies. L’Organisation mondiale de la Santé (OMS) recommande aux autorités nationales de contin...uer à appliquer une approche fondée sur les risques lorsqu’elles mettent en œuvre des mesures relatives aux voyages internationaux dans le contexte de la COVID-19, tout en respectant la dignité, les droits humains et les libertés fondamentales des voyageurs. Cette approche doit prendre en compte le risque d’importation et d’exportation de cas posé par les voyages dans le cadre de l’évolution de la situation épidémiologique, y compris de l’émergence et de la circulation de variants préoccupants du SARS-CoV-2, du déploiement de la vaccination contre la COVID-19 et des enseignements tirés de la riposte à la pandémie, notamment en ce qui concerne la détection précoce et la prise en charge des cas, ainsi que l’application de mesures sociales et de santé publique.

COVID-19 vaccine hesitancy is currently one of the main obstacles to worldwide herd immunity and socioeconomic recovery. Because vaccine coverage can vary between and within countries, it is important
to identify sources of variation so that policies can be tailored to different population groups. ...In this paper, we analyze the results from a survey designed and implemented in order to identify early adopters and
laggers in six big cities of Latin America. We find that trust in government and science, accurate knowledge about the value of vaccination and vaccine effects, perceived risk of getting sick, and being a student
increase the odds to get vaccinated. We also identify potential laggers as women and populations between 20 and 35 years old who are not students. We discuss specific strategies to promote vaccination among
these populations groups as well as more general strategies designed to gain trust. These findings are specific to the context of Latin America insofar as the underlying factors associated with the choice to be
vaccinated vary significantly by location and in relation to individual-level factors.

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.

Social and behavior change (SBC) professionals have often been tasked to find ways to influence knowledge, attitudes, and practices, about vaccines. Now that the COVID-19 vaccines are becoming available worldwide, renewed emphasis and urgency for SBC efforts arise.
To that end, WHO has offered thre...e factors that play a role in vaccine hesitancy, the first two of which can be addressed by SBC: Complacency: Low perceived risk of vaccine-preventable diseases, and vaccination not deemed necessary. Other life/health issues are a greater priority.
Confidence: Low levels of trust in vaccines, in the delivery system, and in health authorities
Convenience: Barriers related to geographic accessibility, availability, affordability, and acceptability of services
This resource page provide a selection of SBC research, tools, and examples that aid in understanding this issue, especially in light of the recent availability of COVID-19 vaccines and the urgency for immunization worldwide.

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.

In our updated analysis we find that, as of September 9, there continue to be wide disparities in access and at current rates, most low-income countries (LICs) and most countries in Africa will not reach global vaccination targets. We also find that, compared to July, the rate at whic...h vaccination would have to increase for LICs to meet global targets is even greater now, due to more ambitious goals and continued low rates of dose administration in these countries.
