 CDC is tracking a new variant of the virus that causes COVID-19 called Delta, or B.1.617.2. There is evidence that this variant spreads easily from person to person.
Get vaccinated as soon as you can to help stop the spread of COVID-19.

Variant of Concern

A variant for which there is evidence of an increase in transmissibility, more severe disease (e.g.,  increased hospitalizations or deaths), significant reduction in neutralization by antibodies generated during previous infection or vaccination, reduced effectiveness of treatments or vaccines, or diagnostic detection failures.

Possible attributes of a variant of concern:

In addition to the possible attributes of a variant of interest

• Evidence of impact on diagnostics, treatments, or vaccines
  • Widespread interference with diagnostic test targets
  • Evidence of substantially decreased susceptibility to one or more class of therapies
  • Evidence of significant decreased neutralization by antibodies generated during previous infection or vaccination
  • Evidence of reduced vaccine-induced protection from severe disease
• Evidence of increased transmissibility
• Evidence of increased disease severity

Variants of concern might require one or more appropriate public health actions, such as notification to WHO under the International Health Regulations, reporting to CDC, local or regional efforts to control spread, increased testing, or research to determine the effectiveness of vaccines and treatments against the variant. Based on the characteristics of the variant, additional considerations may include the development of new diagnostics or the modification of vaccines or treatments.
