Air Travel and Communicable Diseases: Status of Research Efforts and Action Still Needed to Develop Federal Preparedness Plan, Statement of Heather Krause, Director, Physical Infrastructure, Testimony Before the Subcommittee on Space and Aeronautics, Committee on Science, Space, and Technology, House of Representatives [open pdf - 279KB]
From the Document: "The transmission of COVID-19 [coronavirus disease 2019] has been greatly aided by air travel. In light of the pandemic and warnings about the risks of air travel, U.S. passenger airline traffic fell by 96 percent in April 2020 as compared to April 2019. COVID-19 is only the latest communicable disease threat to raise public health concerns regarding the spread of contagion through air travel. Ensuring that the United States is prepared to respond to disease threats from air travel, as well as conducting the necessary research to reduce the risks of contagion, are two vital responsibilities of the federal government. This statement provides information on (1) the U.S. aviation system's preparedness to respond to communicable disease threats and (2) FAA's [Federal Aviation Administration] management of its R&D [research & development] portfolio, including the extent to which disease transmission on aircraft and at airports has been the focus of FAA research."
