This study proposes to use analyses of spatial (temporal and geographical) patterns and bacterial phylogenetics to shed light on the dynamics of pneumococcal transmission. The study will leverage genomic and metadata obtained from cross-sectional samples collected in parts of Blantyre, Malawi from June 2015 and May 2019 to determine if fine scale clustering of S. pneumoanie occurs in either geographical space or time. The results of such analyses will improve understanding of the observed variability in pneumococcal epidemiology and help with design and interpretation of cluster randomised trials.
