Heat maps of TB incidence per 100,000 population per province per quarter. a Heat map with TB incidence normalized per province to demonstrate temporal variation. b Heat map with TB incidence normalized per quarter to demonstrate geographical spread. Legend: Each horizontal bar on the heat map represents a province, ordered by latitude and linked to the map to demonstrate the position. Each vertical bar represents a quarter of a year (3 months) over the 6 years of the study
