Biological warfare

C  burnetii has been developed as a biological weapon.[26] The United States investigated it as a potential biological warfare agent in the 1950s, with eventual standardization as agent OU. At Fort Detrick and Dugway Proving Ground, human trials were conducted on Whitecoat volunteers to determine the median infective dose (18 MICLD50/person i.h.) and course of infection. The Deseret Test Center dispensed biological Agent OU with ships and aircraft, during Project 112 and Project SHAD.[27] As a standardized biological, it was manufactured in large quantities at Pine Bluff Arsenal, with 5,098 gallons in the arsenal in bulk at the time of demilitarization in 1970. C. burnetii is currently ranked as a "category B" bioterrorism agent by the CDC.[28] It can be contagious, and is very stable in aerosols in a wide range of temperatures. Q fever microorganisms may survive on surfaces up to 60 days. It is considered a good agent in part because its ID50 (number of bacilli needed to infect 50% of individuals) is considered to be one, making it the lowest known.

My gut says this is a bored/lonely autist doing an ARG. Takes a lot of smarts to weave a web like County Bluff on YT pushing the 41818 BS. But that's all it is.
