From the GAO [Government Accountability Office] Highlights: "The COVID-19 [coronavirus disease 2019] pandemic has underscored the importance of public health measures aimed at controlling the transmission of communicable diseases. Air travel can play a role in quickly spreading communicable diseases across the world and throughout communities. Given this potential, contact tracing for air passengers is an important measure for protecting public health. GAO was asked to examine CDC [Centers for Disease Control and Prevention]'s process for collecting and managing air passengers' contact information to facilitate contact tracing. This report addresses: (1) the factors that affect CDC's ability to collect this information, (2) recent actions CDC has taken to improve the quality of the information it collects, and (3) how effectively it collects and manages this information. GAO reviewed relevant federal documentation, including regulations, orders, technical guidance, and public comments, as well as available CDC data. GAO also interviewed officials from CDC, U.S. Customs and Border Protection, and the Federal Aviation Administration, and selected representatives from the aviation, travel, and public health industries."
