```

Virus variant types.

voc_pos - All positive tests identified as a variant of concern
voc_known -  All sequencing results reported by laboratories including both positive and negative results for all variants of concern. For this variant_type, especially in the beginning of the surveillance, there are only positive but not negative results available. Therefore anteil_pos is not available in this structure.
voc_digitally_reported -  All sequencing results reported digitally by laboratories including both positive and negative results for all variants of concern. For this variant_type, the period where a lab has reported only positives but not negatives was excluded. Therefore anteil_pos is available in this structure.
B.1.1.7 - All cases with a positive test identifying the variant B.1.1.7 (501Y.V1)
B.1.1.7 & E484K - All cases with a positive test identifying the variant B.1.1.7 and E484K mutation
B.1.351 - All cases with a positive test identifying the variant B.1.351 (501Y.V2)
B.1.617 - All cases with a positive test identifying the variant B.1.617
P.1 - All cases with a positive test identifying the variant P.1 (501Y.V3)
P.2 - All cases with a positive test identifying the variant P.2
S:N501Y - All cases with a positive test identifying the mutation S:N501Y. This does not include variants that have been identified in detail (B.1.1.7, B.1.351 or P.1)
S:N501Y_E484K - All cases with a positive test identifying the mutation S:N501Y and E484K. This does not include variants that have been identified in detail (B.1.1.7, B.1.351 or P.1) and cases for which only the S:N501Y mutation has been identified.

## variant_type Type

`string` ([VirusVariantType](sources-definitions-virusvarianttype.md))

## variant_type Constraints

**enum**: the value of this property must be equal to one of the following values:
