The Report of Q, United States Army, Fort Detrick, dated September twenty‑eighth, nineteen forty‑eight. This document is notable because it details a contemporaneous investigation of plague epidemics in two regions of Manchuria and provides a systematic anatomical pathology summary of the cases. The text was made publicly accessible through The Black Vault archive, uploaded from the original Fort Detrick collection. The entry appears on archive.org under the title “THE REPORT OF Q” and was released to the public without a specific declassification notice, the archive indicating the file as a digitized version of the original report.
