From the Document: "Public health surveillance, or ongoing data collection, is an essential part of public health practice. Particularly during a pandemic, timely data are important to understanding the epidemiology of a disease in order to craft policy and guide response decisionmaking. Many aspects of public health surveillance--such as which data are collected and how--are often governed by law and policy at the state and subfederal level, though informed by programs and expertise at the Centers for Disease Control and Prevention (CDC). The Coronavirus Disease 2019 (COVID-19) pandemic has exposed limitations and challenges with U.S. public health surveillance, including those related to the timeliness, completeness, and accuracy of data. This report provides an overview of U.S. public health surveillance, current COVID-19 surveillance and data collection, and selected policy issues that have been highlighted by the pandemic. Appendix B includes a compilation of selected COVID-19 data resources."
