(Wisconsin) Health officials say the Delta variant of COVID-19 is likely to become dominant in Wisconsin. Dr. Ryan Westergaard, the state’s chief medical officer, says the Delta Variant seems to spread from person-to-person more easily. He says that means less margin for error among those not yet vaccinated against COVID, which he adds is particularly effective against the Delta Variant. In Dodge County, just over 38-percent of the population is fully vaccinated while 40-percent have had at least one dose. In Fond du Lac County, 41.1-percent have completed the vaccination series, that figure is 43-percent in Washington County and Jefferson County, 42.3-percent in Green Lake County. Over half of the population in Columbia County are fully vaccinated.
