n/a: not applicable, no WHO label has been assigned to this variant at this time

All sub-lineages of the listed lineages are also included in the variant, e.g., B.1.429.1 is included in B.1.427/B.1.429 as it is a sub-lineage of B.1.429.

(a) No assessment of transmission is given for variants in the monitoring category, only detected/not detected.

(b) The earliest detections from several different countries are close in time and there is no clearly demonstrated travel link to a specific country that explains the detections.

(c) The property of concern for this variant was the fact that there are reports of difficulties associated with detecting it in upper respiratory tract samples. These difficulties were not caused by primer-template mismatch but rather by the virus not being present in sufficient quantities in the upper respiratory tract.

(d) Any amino acid substitution

The tables are based on genomic, phenotypic, and epidemiological evidence available on a global scale, but focus on the potential impact for the European region. For this reason, the list may deviate slightly from the global variants of concern and interest list and labels produced by WHO and published in the WHO weekly epidemiological update.
