There were two components to the BBC Pandemic study, one focused on the town of Haslemere [16] , and another focused on the wider UK population [17] . Here we present data from the UK national study. Upon using BBC Pandemic app to join this study, users first entered their basic demographic information, including age, household size, gender and occupation. The app then recorded their approximate location at hourly intervals for a 24 hour period. At the end of this period, users recorded each social contact they had made during this period, including information on: the contact's age; the type of interaction (conversational contact, defined as face-to-face conversation of three or more words, or physical contact); the setting of the contact (home, work, school, other); and whether the participant had spoken to that person before.
