Could I still make a workers' compensation claim if I can't point to a specific source of exposure but work around people who have been diagnosed?

Yes. According to the workers’ compensation statute, “Personal injury includes a disease or disability that is due to causes and conditions that are characteristic of and peculiar to the business of the employer and that arises out of and in the course of the employment.” Another way to describe these might be injuries or diseases that arise over time. Remember, the key with any injury is that it must be attributable to work. For example, the statute goes on to state that, “An ordinary disease of life to which the public is generally exposed outside of the employment is not compensable.”
