Lineage: A lineage is a group of closely related viruses with a common ancestor. Variant: A variant is a viral genome genetic code that may contain one or more mutations. In some cases, a group of variants with similar genetic changes, such as a lineage or group of lineages, may be designated by public health organizations as a Variant of Concern VOC or a Variant of Interest VOI due to shared attributes and characteristics that may require public health action.
To receive email updates when a variant classification or definition changes, enter your email address: Email Address. What's this? Possible attributes of a Variant of Interest: Specific genetic markers that are predicted to affect transmission, diagnostics, therapeutics, or immune escape.
Evidence that it is the cause of an increased proportion of cases or unique outbreak clusters. Limited prevalence or expansion in the US or in other countries. Variant of Concern VOC A variant for which there is evidence of an increase in transmissibility, more severe disease for example, 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 significantly 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.
