What law covers you under a work comp injury with a pre existing condition?

In the United States, workers' compensation laws vary by state, but generally, they cover employees who sustain injuries or illnesses related to their work, even if they have pre-existing conditions. Most states follow the "aggravation rule," which allows workers to receive compensation if their work-related activities worsen their pre-existing condition. Additionally, the "major contributing cause" standard may apply, determining if the work-related injury is a significant factor in the exacerbation of the condition. It's essential to consult your state's specific workers' compensation laws for detailed guidance.
