Pulmonary Nontuberculous Mycobacteria, Ontario, Canada, 2020

Abstract

We measured annual prevalence of microbiologically defined nontuberculous mycobacterial lung disease in Ontario, Canada. Mycobacterium avium prevalence was 13 cases/100,000 persons in 2020, a 2.5-fold increase from 2010, indicating a large increase in true M. avium lung disease. During the same period, M. xenopi decreased nearly 50%, to 0.84 cases/100,000 persons.
