Since 16 July 2020, doctors treating Covid-19 patients have provided the Federal Office of Public Health (FOPH) with information on where each infection may have occurred.
According to this data the most likely source of infection is a family member. 27% of recorded cases were reportedly infected this way. The next most likely sources were work (9%) and private parties (3%). Less likely sources included nightclubs, bars, medical staff and unplanned gatherings. These each accounted for around 2% of cases.
The percentages are based on forms submitted for 793 cases recorded between 16 July 2020 and 1 August 2020.
The FOPH data contrasts with data collected in Geneva, which suggests 40% of new cases in the week to 31 July 2020 in the canton were linked to 20 nightclubs.
However, given that 40% of the forms submitted to the FOPH indicated no source of infection the data is not particularly meaningful.

Bea Curtis says
It’s very misleading to write a headline that says family is the main source of infection for two reasons, one which you give (only 60% of forms submitted to the FOHP give the source) and one which you don’t, i.e. family members obviously pick up the virus outside the home. And the most likely places are where there’s no social distancing, like nightclubs and bars. Which is why Geneva closed them.
