Abstract excerpt

BACKGROUND: The molecular and spatial epidemiology of Mycobacterium tuberculosis (Mtb) in relation to diagnostic delays remains underexplored in Kenya. This study was conducted to map the spatial clustering and characterize circulating lineages/sub-lineages of Mtb, and their transmission patterns associated with diagnostic delays in Nairobi County. METHODS: DNA was extracted from 101 Mtb isolates collected from...
