How do I prove my workers' compensation claim?

It depends on the type of your employment. If you are a First Response Employee,  and you are diagnosed with COVID-19 infection either by a physician or as a result of a test, based on your specific type of employment sector and unless proven otherwise, you are considered to have a personal injury that arises out of and in the course of your employment. The rule indicates a positive test or diagnosed by physician. Many tests at this time are not being performed by physicians. Confirmation is not necessary per the rule. Employers always have the opportunity to obtain contrary evidence to present if they choose, and to dispute a claim.
