Variants

This dashboard includes only Variants of Concern, Variants of Interest and Variants Being Monitored currently listed on the Centers for Disease Control and Prevention (CDC) SARS-CoV-2 Variant Classifications and Definitions  and identified to be circulating in Virginia during the pandemic.  Data presented here will not match exactly to the data presented by CDC.

Viruses constantly change through mutation.  A variant has one or more mutations that sets it apart from other variants in circulation.  Variants of a virus are expected to occur naturally over time. SARS-CoV-2 is the virus that causes COVID-19.  Multiple variants of SARS-CoV-2 have been documented in Virginia, the United States and globally throughout this pandemic.  Scientists categorize variants based on how concerning they are.  Other variants that are not presently being tracked are circulating in the population. Visit SARS-CoV-2 Variant Classifications and Definitions for more information on variant classification.

A variant of the virus that causes COVID-19 is considered to be concerning when it increases the risk to human health. The risk to human health could be because a variant may be able to:

  • Spread more easily
  • Cause more severe illness
  • Escape the immune protection provided by available COVID-19 vaccines or by natural infection with the virus that causes COVID-19
  • Make viral tests less accurate
  • Make some treatments less effective

This dashboard lists the number of COVID-19 infections, hospitalizations, and deaths caused by a variant which has been reported in Virginia since December 1, 2020.  Data are presented by date of symptom onset week for infections, date of hospital admission week for hospitalizations, and date of death week for deaths.

Variants are identified by additional laboratory testing of specimens which are positive for COVID-19. The number and percentage of variants within each region are presented by where the person infected with a COVID-19 variant lives.  If an individual person is infected with two separate variants over time, then they will appear as two separate infections on this dashboard.

Variants of Concern

This dashboard also includes demographic information including age group, ethinicity and race, and sex for those persons identified with a current Variant of Concern.
