Despite the decline in the coal industry a new research letter details hundreds of cases of black lung disease in eastern Kentucky. According to the study published recently in the Journal of the American Medical Association, three clinics in southwestern Virginia identified 416 coal miners with the deadly disease from January 2013 to February 2017. Of those, 157 lived in eastern Kentucky. The Lexington Herald-Leader reports that the study provides further evidence that progressive massive fibrosis, commonly called black lung, has surged in recent years among coal miners in the region. Scott Laney, one of the authors of the study, says the findings are shocking. Most of the miners identified in the study were retired and had worked in mines for more than 25 years.
