Relevant virus variants

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

Relevant virus variants, Switzerland and Liechtenstein, 08.06.2020 to 12.05.2021

Virus variants are determined and classified on the basis of their mutations. Since the properties of the virus can change – for example in terms of increased risk of infection, changes in the efficacy of a vaccine or changes in the probability of re-⁠infection – we track these viral mutations very closely.

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

17 446
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

246
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

17
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

24 582
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.

Development over time

Relevant virus variants, Switzerland and Liechtenstein, 08.06.2020 to 12.05.2021

The graphic shows the development of the estimated proportion of relevant virus variants in Switzerland and the Principality of Liechtenstein over the period selected. The line represents the 7-⁠day rolling average (average of previous 3 to subsequent 3 days). The data come from individual laboratories that notify us what material they have analysed for variants.

The daily values are bounded by an upper and a lower value which represent a probability of 95 per cent.
