Trends in US State Public Health Emergency Laws, 2021-2022

Objectives. To identify and categorize US state legislation introduced between January 1, 2021, and May 20, 2022, that addresses emergency health authority. Methods. We adapted standard policy surveillance methods to collect and code state bills and enacted laws limiting or expanding the emergency public health authority of state and local officials and agencies. Results. State legislators introduced 1531 bills addressing public health authority; 191 of those were enacted in 43 states and the District of Columbia, including 17 expanding and 65 contracting emergency authority, 163 regulating use, and 30 preempting local use of specific measures such as mask mandates. Conclusions. State laws setting the scope and limits of emergency authority are crucial to effective public health response. These laws are changing in ways that threaten to reduce response capacity. Tracking changes in health law infrastructure is important for evaluating changes in health authority and ensuring that stakeholders recognize these changes. Public Health Implications. The COVID-19 pandemic called for quick, decisive action to limit infections, and when the next outbreak hits, new laws limiting health authority will make such action even more difficult.
