"figure shows daily analysis of the relative contributions of different "settings" for epidemic spread, April 2021 - March 2022.
 
Upper = types of contact for the average person with COVID-19,
lower = COVID-19 transmissions detected by the app"

Household contacts (more than 8 hours per day) accounted for only 6% of contacts but 39% of transmission events,
whereas fleeting interactions (less than half an hour) accounted for 48% of contacts but only 12% of transmission events.

The repeating wave patterns show how types of contact vary by day of the week. No prizes for spotting Christmas day!"
