Governor Mike DeWine signed House Bill 606 (H.B. 606) into law on September 14, 2020. The new law, titled “Grant immunity to essential workers who transmit COVID-19,” expanded and clarified school districts’ immunity as they prepare to reopen – or perhaps recently reopened – their school buildings for in-person instruction. This alert (1) provides an overview of H.B. 606 as enacted; (2) discusses how it expands school districts’ pre-existing statutory immunity in the event that students or visitors are exposed to COVID-19 on school grounds; (3) explains why the new law does not affect school districts’ liability for their employees’ exposure to COVID-19; and (4) assesses the practical considerations and key takeaways for school districts.
