Storrs, CT — An estimated 31,016 cases of work-related disease in Connecticut occurred in 2023, according to an annual report from the state’s Workers’ Compensation Commission.
Released on Labor Day, the report draws on the most recent data available from the Bureau of Labor Statistics/Connecticut Department of Labor, Workers’ Compensation First Reports of Injury, and physician reports via the Occupational Illness and Injury Surveillance System. It was prepared by University of Connecticut Professor Emeritus Tim Morse.
The data shows that of the estimated cases:
- Around 7,100 were reported by either workers’ comp or physicians.
- Nearly 5,200 were reported via Workers’ Compensation First Reports of Injury.
- 3,500 were estimated by the BLS/CTDOL annual survey.
- Almost 2,300 cases were reported by physicians through the OIISS.
Musculoskeletal disorders, including carpal tunnel syndrome and tendonitis, accounted for 49% of workers’ comp reports and 26% of physician reports. Exposures to bloodborne pathogens was the second-highest category, making up 41% of physician reports and 22% of workers’ comp reports.
Respiratory diseases and poisonings – including asthma and exposure to carbon monoxide and lead – made up 51% of BLS reports, mainly from COVID-19 cases. They also comprised 9% of physician reports and 7% of workers’ comp cases.
“Occupational diseases often develop gradually and can be difficult to recognize, making comprehensive data collection essential for prevention,” Morse said in a university press release.
Added Stephen M. Morelli, chair of the commission: “By identifying trends and high-risk industries, we can work with employers, employees and health professionals to reduce occupational illnesses and create safer work environments for everyone.”
