The variant strain of COVID-19 first discovered circulating widely in England in November and December has now been identified in Wisconsin. Researchers believe this new strain spreads more rapidly and easily than the original strain, but there is no evidence this new strain causes more severe illness or increased risk of death. The strain was identified here in Wisconsin through ongoing surveillance and whole genome sequencing, a routine practice since the pandemic began. All viruses, including COVID-19, change through mutation and new strain variants are expected to occur over time. With emerging mutations possibly being more infectious, it remains critically important to follow best public health practices, including wearing a mask, staying home, maintaining physical distance, and washing your hands frequently.
