CoMix study - Social contact survey in the UK
This study has not yet been peer reviewed.
We present updated reports from the CoMix social contacts survey. Participants reported the total number of direct contacts that they had on the day before the survey, which are people with whom they had at least a brief face-to-face conversation, or with whom they had any sort of skin-to-skin contact. Week 1 links to a peer-reviewed publication of the CoMix study which provides further details of the study questions and the study protocol.
Analyses are presented every two weeks. We aimed to track the reproduction number and mean contacts over time and explore differences in regions.
Note there was a data issue in reports 62-64 therefore the results are not accurate. We keep them here for historical purposes.
