Time spent at locations other than home

Each row corresponds to information from a retrospective interview (interview_id) of a study participant (part_code) who provided information about time spent at a location other than home. Information about time spent at each location was summarized as the daily frequency of visits to that location (absolute_frequency) and the average fraction of the day between 5:00 AM and 10:00 PM spent at that location (absolute_duration). Individuals are stratified by their demographic category (category) and fever status (pathogen). Locations are classified by their landuse designation (landuse_class).每一行数据对应一位研究参与者的回顾性访谈（retrospective interview）信息，该访谈的唯一标识符为interview_id，参与者编码为part_code，该参与者提供了其在非居家场所的停留时长相关信息。各场所的停留时长信息被汇总为两项指标：到访该场所的每日频次（absolute_frequency），以及当日5:00至22:00时段内停留于该场所的平均时长占比（absolute_duration）。研究对象按其人口统计学类别（category）与发热状态（pathogen）进行分层，场所则按其土地利用类型标识（landuse_class）完成分类。
