Omicron is spreading more quickly, but Delta is still the most dominant.

Omicron Variant

The World Health Organization (WHO) said that Omicron hasn’t completely wiped out the Delta variant of coronavirus, and it is still the most common type of coronavirus in the world.
There have been recording highs in Europe, the US, and other places since the Omicron variant of the new coronavirus came out. That has led people to think that Omicron is to blame for a rise in Covid-19 cases. However, many genome sequencing data points to Delta and the World Health Organization (WHO) says Delta is still the most common type of concern globally.
The WHO said that between October 20 and December 19, more than 10.51 million genomes were sequenced around the world, and almost all of them were from Delta. Over the two months, Omicron had about 17,000 cases, which is less than 2% of the total number of Covid-19 cases that were around the world at the same time.
However, this is not the total number of cases found during this time. Public databases like GISAID are used to get the WHO’s number (Global initiative on sharing all influenza data). There is a delay between each country recording cases of Omicron and reporting them to the WHO or other data repositories to keep their records up to date.
All of the cases that have been reported are not sent for a genome sequencing test, as well. For example, this week, the UK had the most Covid-19 cases in a single day, but it’s not clear how Delta and Omicron cases were separated. Omicron infections have been reported in the UK more than 45,000 times. However, the same data have not been available to the public in the same way.
The WHO has been very clear that Omicron has not completely wiped out the Delta variant. Following the designation of Omicron as a variant of concern, many countries have used targeted sequencing strategies to look for the variant.
