UVA COVID-19 Modeling Weekly Update

Key Takeaways

  • Case rates are continuing their steep decline across Virginia. As was the case last week, 34 of 35 districts are in decline.
  • For the third week in a row, the statewide effective reproduction number (Rₑ) is around 0.7, and well below 0.85 for all regions.
  • High case rates persist in the Far Southwest, in the Lynchburg area, and in the western parts of Southside. Residents in these areas should consider masking when in indoor public places.
  • The CDC has adjusted their BA.2 subvariant proportion estimates. They now suggest BA.2 represents 4.7% of new cases in Virginia. Models indicate the subvariant may become dominant by April.
  • Models project that BA.2 may slow, but not stop, case declines across the Commonwealth. Models do not anticipate a BA.2 related surge in the near future.
  • Note that this is an interim report. Models will next be run on 2022-03-02 for release the following Friday.
