COVID Variant Dashboard

Data updated weekly on Monday.
 

About This Dashboard 

Since the start of the pandemic, multiple variants of SARS-CoV-2 have appeared. SARS-CoV-2 is the virus that causes COVID. Most variants do not have significant health impacts, but some may affect COVID transmission, disease severity, testing, treatment, or vaccine effectiveness, and should be routinely monitored.  Vaccine effectiveness and variants continue to be monitored and studied nationally and globally. For information on vaccinations in Santa Clara County please visit our vaccination dashboard. 

Santa Clara County follows the CDC SARS-CoV-2 classification scheme and definitions, which includes four classes of SARS-CoV-2 variants:

• Variant of High Consequence (VOHC) is used to describe a variant for which there is clear evidence that prevention or medical countermeasures have reduced effectiveness.
• Variant of Concern (VOC) is used to describe a variant that has already been found to have a significant impact on health, such as being more contagious, more likely to cause severe illness, or less responsive to vaccines or treatment.
• Variant of Interest (VOI) is used to describe a variant which has been associated with significant genetic changes and may require appropriate public health actions.
• Variant Being Monitored (VBM) is used to describe all variants with substitutions of concern, including previous VOIs and VOCs, in the United States that are currently being monitored by the CDC to learn more about their public health impact, but are not thought to pose a significant or impending risk to the public.
