Wisconsin detects new fast-spreading COVID-19 variant

On January 12 the Wisconsin Department of Health Services discovered the presence of a new strain of SARS-CoV-2, the virus that causes COVID-19, in Wisconsin.

The particular variant, referred to as B.1.1.7, was first discovered circulating widely in England during November and December of 2020. Based on epidemiologic and modeling studies, researchers believe that this new strain spreads more rapidly and easily than the original strain of SARS-CoV-2. However, there is no evidence that the new strain causes more severe illness or increased risk of death.

“We already know that COVID-19 is easily transmitted through respiratory droplets, and with this new variant appearing to be even more infectious, taking preventative measures like wearing a mask and physically distancing are even more important,” said DHS Secretary-designee Andrea Palm.

In Wisconsin, the strain was identified through ongoing surveillance and whole genome sequencing, a routine practice since the onset of the COVID-19 pandemic. All viruses, including the virus that causes COVID-19, change through mutation, and new variants of the virus are expected to occur over time.

“Mutations among viruses are very common. It’s not unusual – in fact, it’s expected. As time goes on in the pandemic and the virus continues to replicate on a large scale, the genetic sequence of the virus will change,” said Chief Medical Officer Dr. Ryan Westergaard.
