Multi-drug resistant tuberculosis in Chuuk State Federated States of Micronesia, 2008-2009.

Multi-drug resistant tuberculosis (MDR TB) is a growing public health concern, particularly for the Pacific, where rates of tuberculosis infection are extremely high. In May 2008, a cluster of patients with MDR TB were identified in Chuuk State, Federated States of Micronesia. A multi-agency investigation led to the eventual discovery of 21 cases, and over 100 latent TB infections. Incomplete implementation of Directly Observed Therapy (DOT) and contact investigation were major contributors to the outbreak. The problem of MDR TB in Chuuk was controlled only after a concerted effort on the part of multiple agencies coupled with the highest level of political commitment.
