The daily mean number of reported contacts between age groups, in urban Blantyre, Malawi between April and July 2021. The number in each cell represents the daily mean number of contacts between two age groups from 1000 bootstrap replicates, corrected for reciprocity between participants and contacts, and weighted for day of the week. The matrices show the daily mean number of all contacts (A), physical contacts (participant’s skin to skin touch with a contact) (B) and non-physical contacts (participant’s two-way close verbal conversation lasting for ≥5 min and with ≥3 words exchanged with a contact) (C).
