Description:

Updated Aug. 6, 2021

Viruses constantly change through mutation, and new variants of a virus are expected to occur. Sometimes new variants emerge and disappear. Other times, new variants persist. Multiple variants of COVID-19 have emerged in the United States. At this point, the original variant that caused the initial COVID-19 cases in January 2020 is no longer circulating as newer variants have increased.
