Information on the current situation, as of 24 January 2023
Following the changes to testing cost strategy with effect from 1 January 2023, numerous indicators are now only presented in weekly form. In a further modification, deaths are now only shown at the Switzerland and Liechtenstein level, for data protection reasons.

Detected virus variants, St. Gallen, 04.04.2022 to 08.01.2023
The data published here is based on information from the national genomic SARS-CoV-2 surveillance programme. The laboratories of university hospitals and larger regional hospitals as well as selected private laboratories and sequencing programmes are affiliated to the programme. (National genomic SARS-CoV-2 surveillance programme – monthly reports). Current surveillance covers all relevant virus variants that show high transmissibility and/or immune-evasive characteristics and thereby influence the virus’s circulation and/or the burden of disease. The graph is updated continuously in line with the current state of development.
The novel coronavirus (SARS-CoV-2), which causes the infectious disease COVID-19 is constantly changing due to mutations in its genome (changes in the genetic code). Virus variants are designated and classified on the basis of these mutations. Most mutations have little or no impact on the properties of the virus. However, some SARS-CoV-2 variants are characterised by altered pathogen properties which can influence the epidemiological situation, for example because they are more contagious, cause more serious illness or evade a person’s immune response even though they have had an infection or have been vaccinated (immune evasion). For most known variants there is still a high level of protection against severe courses of the disease for people who are fully vaccinated. For some variants there are still no conclusive findings.
Experts regularly evaluate the latest evidence on known and emerging virus variants and assess the potential impact of the circulating virus variants on the epidemiological situation in Switzerland and Liechtenstein. The time frame desired can be selected with the slider below the graph.
