There are basically two types of bioterrorism: For causing spectacular damage as quickly as possible, pathogens with a rapid effect are employed, as seen in the 2001 anthrax attacks in the USA. Conversely, if the goal is for the attacks to remain undetected for as long as possible, pathogens with a long latency period are utilized. Conspiracy theories primarily focus on this second form of bioterror, alleging that viruses or bacteria are intentionally released by unscrupulous governments or malevolent elites to either reduce the global population or target specific groups in order to gain control over them. However, experts find these theories speculative and rather implausible.
