Omicron variant of concern: ongoing research, data, publications and preprints

February 2022: We have stopped tracking updates related to Omicron VoC. This page will stay available as an archive. NB: Some sections on this page that fetch automatically information from other sections of the Portal will continue to update.

On this page we have compiled current knowledge on Omicron, the latest SARS-CoV-2 variant to be designated as a Variant of Concern (VOC). This includes available data, ongoing research efforts, initial findings, among other things related to Omicron. Please see this page for information on other VOCs.

We make all possible efforts to track preprints, publications, and other resources related to Omicron and link them below. Researchers and organisations from around Sweden are also welcome to submit their datasets and to make relevant announcements on this page. If you feel like something is missing that should be included, or you wish to make a submission/announcement, please use the forms below or email us at datacentre@scilifelab.se. The team behind the COVID-19 Data Portal continuously monitors incoming suggestions, and new items are published as soon as possible.

Available data

This section presents a list of the available data related to Omicron (or related work that could benefit research into this variant) shared by researchers affiliated to a Swedish research institute. We welcome the submission of suggestions for additional datasets, either using the form below or by e-mail: datacentre@scilifelab.se. All submissions will be moderated by the Portal team before they appear on the page.

Data available from research groups in Sweden

Omicron overcame delta in a couple weeks in analysed Swedish wastewaters

2022-01-17 17:26

By quantifying K417N and wild-type K417 mutations we estimated the ratio of omicron and delta in major cities. In all places up till Christmas delta was the dominant variant but during the holiday weeks omicron took-over. By the 10th of January delta fall below the detection limit of the assay, indicating outcompeting by omicron. For more, check out our latest press-release:

Omicron VoC detected in Uppsala wastewater

2022-01-13 14:40

Anna Szekely shared first results in work attempting to detect Omicron VoC in Uppsala wastewater samples. Here they are: ‘On w51 delta dominated, omicron mutations were barely detectable. On w52 delta continued to increase but omicron also showed a strong signal (probably similar ratio of the 2 variants). On w1 delta started to decrease and omicron more than doubled.’ See Anna Szekely’s twitter account for future updates.

Preliminary results on neutralization resistance of the Omicron VoC from the Murrell lab

2021-12-20 12:55

On December 7 the Murrell lab has made public two sets of prelimiary results on neutralization resistance of the Omicron VoC: Neutralization resistance of the Omicron SARS-CoV-2 Variant of Concern against monoclonal antibodies and Quantification of the neutralization resistance of the Omicron Variant of Concern. Both are prelimiary reports, subject to modification. I recommend following Ben Murrell’s Twitter account for updates.

Exploring Omicron VoC in Sweden using Nextstrain

There is a Nextstrain build maintained by the Neher lab and NextStrain team that focusses specifically on sequences from Sweden, follow this link for Omicron focus. Please keep in mind that quality of the analyses by Nextstrain depends on the amount and quality of available data so the results should be taken with caution.

There are 4 main visualisation panels in Nextstrain:

A phylogenetic tree showing the relationships between variants.
A geographic map showing which variants have been detected in Sweden and their relative prevalence by default. Other aspects of the data related to sequences (e.g. the sampling date) can be displayed instead using the Color By dropdown menu to the left of the visualisations panel. NOTE: Some data are visible for other countries, as a sample from all over the world is needed to properly root the phylogenetic tree (see here for information on subsampling procedures).
A ‘diversity’ plot that shows information related to differences in amino acids and nucleotides across variants.
A frequency plot showing the relative dominance of variants.

For more information on what is shown in the panels, please see e.g. this 2018 paper by Hadfield et al., or this section on interpreting analyses in the Nextrain documentation. Further, to understand how different visuaalisations relate to each other, see the narrative written by Hodcroft et al. in 2020.
