While cases are decreasing, cases, hospitalizations, and percent positivity are all still very elevated. Although testing capacity has been increasing, high percent positivity means we are still likely missing cases in our case counts.

The BA.2 Omicron lineage is not yet prevalent in Wisconsin.

The vast majority of Omicron lineages detected in Wisconsin so far have been the descendant Pango lineage BA.1. The BA.2 descendant lineage, which differs from BA.1 in some of the mutations, including in the spike protein, is increasing in many countries and out-competing BA.1 in places such as Denmark. It’s unknown at this time if BA.2 behaves differently from BA.1, such as if it is more transmissible.

For more information on BA.2, read the WHO’s variant tracking page and the UK’s statement on BA.2 as a variant under investigation.
