The purpose of this LSU NCBRT presentation is to review the different types of intentional biological incidents. This intentional use of biological agents as weapons can be a biocrime or an act of biowarfare, bioterrorism, or agroterrorism. To induce social disruption, an offender might select a particular biological agent because of its ability to be highly contagious and debilitating. Intentional incidents may involve a wide area of exposure at one time or exposure at multiple locations.
