Spatiotemporal Modeling of Tuberculosis Transmission Risk in a Clinical Waiting Room Using Environmental and Patient Movement Data: Impact of Simple Patient Management Interventions - NCT07927881

Sponsor: Centre for Infectious Disease Research in Zambia Conditions: Tuberculosis (TB) To establish a novel approach for estimating the risk of TB transmission in a healthcare clinic in a high TB/HIV setting in Zambia using data on patient characteristics, indoor CO2 and bioaerosol measurements, and patient flows from video sensors. The proposed study has an observational design, employing exposure assessment methods and implements interventions targeting patient flow. Briefly, we will collect patient-related information (anonymous patient tracking, clinical patient information) and environmental data (CO2 levels, particle concentrations) in Kanyama first level hospital in Lusaka, Zambia, over a period of 6 weeks for approximately 6 hours per day.
