Which biological agent is classified as a potential CBRN threat?

Anthrax is classified as a potential CBRN (Chemical, Biological, Radiological, and Nuclear) threat due to its historical use as a bioweapon and its ability to cause severe illness and high mortality rates in exposed individuals. Anthrax is caused by the bacterium Bacillus anthracis, which forms resilient spores that can remain viable in the environment for long periods. When these spores are inhaled, ingested, or come into contact with broken skin, they can lead to serious health issues that require immediate medical intervention.

The potential for anthrax to be disseminated through aerosols makes it particularly dangerous in a bioterrorism context, as it can affect a large number of people quickly. Moreover, its availability in laboratories and its hardiness in various environments heighten the threat it poses.

While the other biological agents listed also represent significant threats in different contexts, anthrax stands out as a clearly defined potential CBRN threat category due to its established history of use in attacks and its characteristics that allow for ease of dissemination and lethality.
