Biological warfare involves the use of living organisms or their toxic byproducts, such as pathogens or bacterial toxins, as weapons of mass disruption. This field focuses on the deployment of biological agents designed to incapacitate or kill living targets. Such agents are drawn from diverse sources, including bacteria, viruses, and fungi. From a scientific standpoint, the discussion centers on the characterization of these agents, their transmission mechanisms, and methods for mitigating their impact. Research into countermeasures and detection systems is a critical area of study, aiming to prevent the misuse of biological materials and to develop effective prophylactic and therapeutic interventions against novel or modified threats.
