Contact mixing patterns.
<p>Part A: Distribution of overall number of contacts (with mean shown as a dashed line). Part B: Mean (dashed line) contact rate per person per day, with boxplots showing median (centre line) and interquartile range (IQR) of contact rates per age group per day. Part C: Contact rate surface (heat map) expressing the mean number of contacts between an individual participant in each age group with individuals in each age group. Part D: Population level numbers of contacts per day within and between age groups (estimated from the matrix defined in (C) scaled by the age-specific resident population size).</p

<p>Mixing patterns for 371 participants in rural areas (Part A) and 197 participants in semiurban areas (Part B).

Baseline characteristics of 10,042 contacts by participants in a diary study in the Kilifi Health and Demographic Surveillance System, Kenya.
â•ž<p>Missing records as a proportion of the total contacts 10,042): Relationship to participant (198, 2.0%); Sleep in same room (22, 0.8%); Ever met the contact before (298, 3.0%); Frequency of meeting (38, 0.4%).</p>$<p>While 63% of contacts with family members (parents, spouses, children and siblings),only 28% live in the same household. Members of the same family could be living in different households and share a common compound (homestead).</p>â–¡<p>Frequency of meeting: daily (on a day-to-day basis); regularly (more than four times a week); often (once or twice a week); rarely (once or twice a month).</p
Map of the study area.
<p>The inset shows the location of the KHDSS in relation to the former Kilifi District (part of Kilifi County). The study area locations are conventionally categorised as semiurban (Kilifi Township [denoted A] and Tezo [B]), and rural (Ngerenya [C], Roka [D] and Matsangoni [E]).</p
