As of December 16, 2021, the Omicron variant has been identified in 89 countries in all six WHO regions.

The Omicron variant has now been identified in 89 countries and is spreading much faster than the Delta variant in places where community transmission is high, with a doubling time of 1.5-3 days, the WHO said. B.1.1.529): Technical Summary and Priority Actions for Member States Report Friday, the World Health Organization said that given the data currently available, it is likely that Omicron will outperform Delta where community transmission occurs.

“Omicron is rapidly spreading in countries with high levels of population immunity and it remains uncertain to what extent the observed rapid growth rate can be attributed to immune evasion, increased intrinsic transmissibility, or a combination of the two.” In 2021, the Omicron variant was identified in 89 countries across all six WHO regions.

The current understanding of the Omicron variant will continue to evolve as more data becomes available.” There is firm evidence that Omicron has a significant growth advantage over Delta. It spreads much faster than the delta variant in countries with documented community transmission, with the WHO said it is doubling The time is between 1.5 – 3 days.

The World Health Organization classified Omicron, or the B.1.1.529 variant, as a variant of concern (VOC) on November 26 after it was first detected in South Africa. There are still limited data on the clinical severity of Omicron. The World Health Organization said more data is needed to understand the severity profile and how risk is affected by vaccination and pre-existing immunity.

The overall threat posed by Omicron depends largely on the transmissibility of the variable; How well vaccines and prior infections protect against infection, transmission, clinical illness, and death; the virulence of the variant compared to other variants; And how the population understands these dynamics, perceives risks, and pursues control measures, including public health and social measures, he said, is still limited data available, and no peer-reviewed evidence, about the efficacy or efficacy of the vaccine yet for Omicron, the World Health Organization added.
