Table 2. Potential epidemiologic links among patients in six of 15 MTB genotype clusters based on either co-location at a shared site or time spent at geographically adjacent locations (within 100 meters of one another) in the time leading up to TB diagnosis, using GPS coordinates of sites of work, clinic, socializing, and household.

Patients in the remaining nine of 15 MTB genotype clusters had no shared or neighboring locations identified.

Cluster Number	TB cases	HIV+ TB Cases	Shared locations	Neighboring locations
1	3	1 of 3	-	Patient A (HIV-) workplace (bank) is <100m from 2 social venues (video hall, church) visited by Patient B (HIV-)
3	2	1 of 2	2 TB cases (one HIV+ and one HIV-) share the same local clinic	-
7	2	2 of 2	-	• Patient A’s workplace (school) is <25m from pharmacy visited by Patient B • Patient A’s household is <50m from pharmacy visited by Patient B • Patient B’s workplace (transport hub) is <25m from social venue (market) visited by Patient A
8	2	None	-	Patient A’s household is <100m from pharmacy and social venue (market) visited by Patient B
14	2	None	-	Patient A’s pharmacy is <50m from social venue (market) visited by Patient B
15	2	1 of 2	2 TB cases share the same local clinic	Patient A’s (HIV-) clinic is <100m from both household and social venue (market) visited by Patient B (HIV+)
