What Are Biological and Toxin Weapons?
Biological weapons are complex systems that disseminate disease-causing organisms or toxins to harm or kill humans, animals or plants. They generally consist of two parts – a weaponized agent and a delivery mechanism. In addition to strategic or tactical military applications, biological weapons can be used for political assassinations, the infection livestock or agricultural produce to cause food shortages and economic loss, the creation of environmental catastrophes, and the introduction of widespread illness, fear and mistrust among the public.
Almost any disease-causing organism (such as bacteria, viruses, fungi, prions or rickettsiae) or toxin (poisons derived from animals, plants or microorganisms, or similar substances produced synthetically) can be used in biological weapons. The agents can be enhanced from their natural state to make them more suitable for mass production, storage, and dissemination as weapons. Historical biological weapons programs have included efforts to produce: aflatoxin; anthrax; botulinum toxin; foot-and-mouth disease; glanders; plague; Q fever; rice blast; ricin; Rocky Mountain spotted fever; smallpox; and tularaemia, among others.
Biological weapon delivery systems can take a variety of forms. Past programmes have constructed missiles, bombs, hand grenades and rockets to deliver biological weapons. A number of programmes also designed spray-tanks to be fitted to aircraft, cars, trucks, and boats. There have also been documented efforts to develop delivery devices for assassinations or sabotage operations, including a variety of sprays, brushes, and injection systems as well as means for contaminating food and clothing.
In addition to concerns that biological weapons could be developed or used by states, recent technological advances increase the likelihood that these weapons could be acquired or produced by non-state actors, including individuals and terrorist organizations.

The 20th century saw the use of biological weapons by individuals and groups committing criminal acts or targeted assassinations, biological warfare conducted by states, and the accidental release of pathogens from laboratories. There were also several false accusations of biological weapons use, highlighting the difficulty in differentiating between naturally-occuring disease, accidents, and deliberate use.
In practice, should a suspicious disease event occur, it would be difficult to determine if it was caused by nature, an accident, sabotage, or an act of biological warfare or terrorism. Consequently, the response to a biological event, whether natural, accidental or deliberate, would involve the coordination of actors from many sectors who together posses the capability to determine the cause and attribute it to a specific source. Likewise, the preparedness for and prevention of such an event should also involve multi-sectoral coordination. For more information about preparing for and responding to disease outbreaks and biological weapons attacks, please see the frequently asked questions published by the World Health Organization.
Because of the wide spectrum of potential biological hazards, efforts to manage the risks should be multi-disciplinary, multi-sectoral, and above all, coordinated. As such, the BWC relies primarily on a network approach based on coordination with international, regional, and nongovernmental organizations and initiatives as well as other nonproliferation regimes in order to address the interconnected nature of biological threats in a holistic manner. Under the framework of the BWC, improved coordination would provide positive externalities for managing disease, whatever the cause. Such an approach ensures that resources are used optimally to provide benefits for many. In this sense, for example, building capacities across sectors to monitor disease would not only strengthen the ability to detect and respond to a biological attack, but it would provide states with the capacity to track and mitigate naturally occurring disease thus vastly improving public health worldwide.
As the Secretary General noted:
"to manage the full spectrum of biological risks, you need a cohesive, coordinated network of activities and resources. Such a network will help to ensure that biological science and technology can be safely and securely developed for the benefit of all.”
