Nontuberculous Mycobacterial Infection in Wisconsin Adults and Its Relationship to Race and Social Disadvantage.

Over 90% of NTM infections were from respiratory sites, with the vast majority caused by MAC. Rapidly growing mycobacteria predominated as skin and soft tissue pathogens and were important minor respiratory pathogens. We found a stable annual incidence of NTM infection in Wisconsin between 2011 and 2018. NTM infection, occurred more frequently in non-white racial groups and in individuals experiencing social disadvantage, suggesting NTM disease may be more frequent in these groups as well.
