From the document: "On August 21, 2017, a total solar eclipse was visible in a path across the U.S. from Oregon to South Carolina, from early morning through the afternoon. It was expected that millions would travel to locations across the country to view this rare event. [...] The next solar eclipse is expected to occur on April 8, 2024 and will be visible across Central and North America passing over Mexico, through the U.S. from Texas to Maine, and then through parts of Canada. It [sic] expected to last up to 4 minutes and 27 seconds, which is almost double the duration of the 2017 solar eclipse. To address planning and response concerns and help local emergency healthcare providers plan for these gatherings in 2017, the ASPR TRACIE [Administration for Strategic Preparedness and Response, Technical Resources, Assistance Center, and Information Exchange] team collected fact sheets, checklists, locally developed guidance documents, and news articles on eye safety, injury treatment, and planned mass gatherings in rural and urban areas. This document was updated in September 2022 to include new information and resources pertaining to the upcoming 2024 solar eclipse."
