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 global increase of healthcare-associated infections (HAI) presents a growing concern in healthcare worldwide. According to the European Centre for Disease Prevention and Control (ECDC), the annual number of HAI exceeds 2.6million and produces the highest estimated amou...nt of disability-adjust-ed-life-years, surpassing all other reported communicable diseases in the European Union and European Economic Area. Multi-drug-resistant Gram-negative (MDR-GN) bacteria have become increasingly common as a cause for HAI, such as central line-as-sociated bloodstream infections, wound or surgical site infections and catheter-associated urinary tract infections
