The Expert Groups of the Swiss National COVID-19 Science Task Force address urgent issues regarding the COVID-19 crisis in Policy Briefs, which are discussed and approved by the Advisory Panel and published on our website. They reflect the thinking of the Taskforce on this topic at that time. If required, the policy briefs are updated in the light of new studies or other data.
Masks are recommended where social distancing cannot be respected, and mandatory in certain enclosed spaces such as public transport, as well as schools, and shops in certain cantons. They are protective of the wearer and especially of others, and as such are part of the bundle of measures needed to keep the COVID19 pandemic under control.

The second wave of the COVID-19 pandemic raises additional challenges for businesses in sectors that are affected by non-pharmaceutical policy interventions and/or by collapsing consumer and intermediate demand. Wages continue to be compensated through well-established policy instruments. However, since the discontinuation of the Covid-19 bridging credits in July, no policy tool has so far been activated to support affected businesses with respect to their fixed capital costs.
The TTIQ strategy aims at identifying index cases through testing, tracing their contacts as well as potential clusters that are potentially the source of their infection, and to isolate cases and quarantine contacts. Based on lessons from the start of the second wave, we make 8 recommendations aimed at ensuring the scalability and efficacy of TTIQ in Switzerland.
