Tools and practical guidance for achieving high uptake
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).

Early detection, assessment and response to acute public health events:
This report explores the reasons why global health is critical to medicine and what this means for medical education. It argues that an understanding of global health is important for all students and practicing doctors, rather than being an ‘add-on’ or ‘option’ for specialization.
Interim Guidance October 2022. This addendum addresses some of the methodological aspects of VE evaluations that have been learned during the past year, as well as those that have become relevant in the current epidemiological setting of the COVID-19 pandemic. For some of the COVID-19 vaccine method...ology issues there are still insufficient data to make a recommendation, in which case different options for approaching VE evaluations are presented.

The Manual for Participants is primarily meant for the participants of a 3 and a half day training course in Emergency Triage, Assessment and Treatment.
The guidelines address timing, number and place of postnatal contacts, and content of postnatal care for all mothers and babies during the six weeks after birth. The primary audience for these guidelines is health professionals who are responsible for providing postnatal care to women and newborns, ...primarily in areas where resources are limited. The guidelines are also expected to be used by policy-makers and managers of maternal and child health programmes, health facilities, and teaching institutions to set up and maintain maternity and newborn care services.
