Why, Immunologically, Housing‐Related Fungi and Endotoxins (and Other Chronic Pro‐Inflammatory Stressors) Risk Latent Tuberculosis Reactivation, Severe Asthma, and Translocating and Invasive Infections in Indigenous Communities in Canada

American Journal of Human Biology, Volume 38, Issue 4, April 2026.
ABSTRACT Type 1/M1/TH1 and type 3/M1/TH17 pro‐inflammatory switches are risks for latent Mycobacterium tuberculosis (Mtb) reactivation and ongoing infection transmission. This paper considers the heavy toll of reactivation risk in Indigenous communities in Canada and the chronic, everyday pro‐inflammatory stressors connected with type 3/M1/TH17 immune ...
