These data are based on reports from laboratories that sequence the virus material (analyse sequences of the genome) or examine it specifically for mutations. These are non-representative samples.
Virus variants overview

Different methods can be used to identify the different mutations of the virus. Detected viral mutations such as S:N501Y are clues that a new variant of the virus may be present. For conclusive confirmation the entire genetic material must be analysed.
| Variants | Identified |
|---|---|
| B.1.1.7 (501Y.V1) This virus variant is considered to be of concern because it is suspected to be more easily transmitted from person to person (first discovered in the UK in summer 2020). | Identified CHFL 16 393 |
| B.1.351 (501Y.V2) This virus variant is considered to be of concern because the probability of re-infection and reduced vaccine efficacy are suspected (first discovered in South Africa at the end of 2020). | Identified CHFL 242 |
| P.1 (501Y.V3) This virus variant is considered to be of concern because the probability of re-infection and reduced vaccine efficacy are suspected (first discovered in Brazil at the end of 2020). | Identified CHFL 13 |
| S:N501Y – mutation containing The three virus variants B.1.1.7, B.1.351 and P.1 have this mutation. Detection of the S:N501Y mutation is thus an indication of a relevant variant. Once it has been identified we assign the case directly to the proven variant. | Identified CHFL 24 203 |
| S:N501Y and E484K- mutation containing The virus variants B.1.351 and P.1 have this mutation. Detection of the S:N501Y mutation in combination with the E484K mutation is thus an indication of a relevant variant. Once it has been identified we assign the case directly to the proven variant. | Identified CHFL 805 |
| Total | Identified CHFL 41 656 |
