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).

Diabetes is an increasingly prevalent yet under-recognised health crisis in Africa, driven by demographic and socioeconomic transitions. In 2021, 24 million adults in the region were living with diabetes, and this figure is expected to increase by 129% by 2045.
A summary of health effects, resources, and adaptation examples from health departments funded by CDC’s Climate and Health Program
This I-Kit provides essential information and tools for responding to an outbreak using an SBCC approach. It presents a series of nine units, each accompanied by exercise worksheets to help link the SBCC theory to practice.
The worksheets in each section are typically followed by a completed exam...ple. The completed examples will likely include information about an emergency that, during an actual event, might not be immediately available. This was done to illustrate the full range of information to inform a strategic communication response.
