ESTABLISHING  KEY  DEFINITIONS

Definitions and terminology need to be emphasized, as there have been multiple terms in the biological space utilized over the years in DoD and medical culture. When most individuals think of biothreats, their thoughts tend to go to infectious diseases (IDs) such as anthrax, plague, and Ebola, or toxins such as botulinum or ricin, which are listed as “bioterrorism agents” or “biowarfare agents.” However, infectious diseases have been artificially separated into “endemic diseases” and “biological warfare agents” over time, for multiple reasons, within DoD and medical culture. This separation is not relevant to the clinician managing a patient, or patients presenting with various non-specific symptoms and signs when an all-hazards approach is needed. This CPG will utilize the definitions from the DoD BPR and the National Biodefense Strategy as a core, with supplementation from current U.S. doctrine, North Atlantic Treaty Organization (NATO) doctrine and other appropriate sources, when doctrinal definitions are not available. 

The following are key definitions to understand:

Biodefense:1,2  Actions to counter biological threats, reduce risks, and prepare for, respond to, and recover from bioincidents.

Biological Hazard (biohazard):1,2  A biological agent or biologically active substance, regardless of origin (e.g., naturally-occurring or bioengineered), that represents an actual or potential danger to humans, animals, plants, or the environment.Terms describing subtypes of potential biohazards:

Biological Incident (bioincident): 1,2

                 OR

                   OR

Biological threat (biothreat):1,2 An entity involved with, or a situation involving, a biohazard that can cause a bioincident.

Biological Select Agents and Toxins (BSAT):17 Biological agents and toxins that have been determined to have the potential to pose a severe threat to public health and safety, to animal and plant health, or to animal or plant products, which must meet specific handling or transportation requirements.Can be endemic, emerging or biowarfare agents.

Endemic diseases:10 The constant presence (with a certain frequency of circulation) of a disease or infectious agent within a given geographic area or population group; may also refer to an expected prevalence of a given disease within such area or group. Examples: Tropical IDs such as malaria and dengue, normal annual respiratory diseases.

High Consequence Infectious Disease (HCID):11,12,13 There is not a standardized definition for HCID amongst different sources at this time. However, per Joint Publications (JP) 4-02, an HCID is a disease that includes any confirmed or suspected infection with a pathogen that meets either of the following criteria:

                OR

Examples: Viral hemorrhagic fevers (Ebola, Lassa, others), Middle East respiratory syndrome (MERS), novel influenza viruses, Nipah virus, pneumonic plague, etc.11,13

Imported diseases:15 Infectious diseases originating in one geographically delineated ecosystem that are carried (by travel or immigration) to another geographically delineated ecosystem by an infected individual, animal, or disease vector.Example: Cholera in Haiti in 2010.

Medical intelligence:12 Produced by National Center for Medical Intelligence (NCMI) and consists of the collection, evaluation, and analysis of information concerning the health threats and medical capabilities of foreign countries and non-state actors that have immediate or potential impact on policies, plans, or operations.

Toxic Industrial Biologicals [TIBs]:16 Biological material that is manufactured, used, transported, or stored by industrial, medical, or commercial processes, which could pose an infectious or toxic threat.Example: Medical waste from a hospital or laboratory facility.

Toxin:6  The poisonous product of a living organism. A toxin can also be synthesized.
