Betweenness and the movement of Nm around NYC neighborhoods.

Locations with higher betweenness values have a darker colored circle. Most arrows represents single transmission event between neighborhoods with the 3 exceptions that have slightly thicker arrows: (1) two transmissions happened between BK35 (Stuyvesant Heights) and BK75 (Bedford), (2) two transmissions happened within BK61 (Crown Heights North), (3) three transmissions happened within BK35 (Stuyvesant Heights). Arrows colored blue represent those transmissions that were part Ob1. Ob2 is designated with arrows colored either red for the closely related subclade and orange for the rest of the outbreak isolates. The neighborhood codes are all the official designation from New York City Neighborhood Tabulation Areas. A key for those referenced is in Table A in S1 File. Those from the same borough start with the same letters; BX:Bronx, BK:Brooklyn, MN:Manhattan, SI:Staten Island, QN:Queens.
