Brief Summary

Title: A Prospective Household observational cohort study of Influenza, Respiratory Syncytial virus and other respiratory pathogens community burden and Transmission dynamics in South Africa (The PHIRST Study) This study will improve understanding of the community burden of influenza, RSV, pertussis, tuberculosis and pneumococcal infection in South Africa. It will also provide data on the carriage prevalence of meningococcus and diphtheria. The data generated from this study will also provide important information on the transmission dynamics of influenza, RSV, pertussis and pneumococcus in the community allowing to better strategize interventions (including targeted vaccination strategies) and evaluate their potential impact. Moreover, there is an absence of prospective data on tuberculosis infection from high tuberculosis burden countries. The data generated will both inform modelling of transmission, sample size for prevention studies and surveillance assessing the impact of the National Tuberculosis Control Program.
