It infects the lymph nodes in the chest first, rather than the lungs themselves, a condition called hemorrhagic [[mediastinitis]], causing bloody fluid to accumulate in the chest cavity, thereby causing shortness of breath.

Symptoms include high fever, extreme shortness of breath, shock, and rapid death within 48 hours in fatal cases.<ref name=":0">{{Cite book|url = http://www.usamriid.army.mil/education/bluebookpdf/USAMRIID%20BlueBook%207th%20Edition%20-%20Sep%202011.pdf|title = USAMRIID's Medical Management of Biological Casualties Handbook|last = [[USAMRIID]]|date = 2011|isbn = 9780160900150|edition = 7th|publisher = [[US Government Printing Office]]|quote = For the attacks of 2001, CFR was only 45%, while before this time CFRs for IA were >85% (p. 37)|url-status = dead|archive-url = https://web.archive.org/web/20150209044622/http://www.usamriid.army.mil/education/bluebookpdf/USAMRIID%20BlueBook%207th%20Edition%20-%20Sep%202011.pdf|archive-date = 9 February 2015|df = dmy-all}}</ref>
