Extraordinarily high incidence rates of tuberculosis among Greenlanders living in Denmark, 2006–2022

TB poses a significant public health challenge for Greenlanders in Denmark. Their high incidence combined with elevated clustering and reinfection rates suggest substantial active TB transmission, and their cluster distribution indicates that many infections are locally acquired rather than reactivations of infection acquired in Greenland. Greenlanders with TB in Denmark are likely part of a socially marginalised minority with TB high-risk behaviours similar to Danes developing TB. These findings highlight the need for targeted TB prevention and control strategies for Greenlanders residing in Denmark.
