Deliberate events

    Overview

    Deliberate events (DEs) are malicious act with intentions to cause harm to the target. Traditionally, DEs involve the use of hazardous substances such as chemicals, biological agents, toxins or radio-nuclear materials (CBRN) while emerging threats include disinformation, misuse of digital, cyber means and other new technologies.

    DEs can cause harm in several ways, for example through the intentional release of a harmful material or a dangerous pathogen directly targeting humans and/or animals, or indirectly through contaminating food or water, destroying crops or damaging the environment.

    Addressing DEs involves both health and security dimensions. The health sector’s role is to protect and manage the health and well-being of those at risk of or affected by DEs. The security sector and law enforcement’s role is to identify and control the source of the DE and prevent the situation from worsening (see Strengthening the global health-security interface).

    Preparing for DEs is an integral part of developing and updating national emergency preparedness and response plans. The work of WHO focuses on increasing Member States’ awareness, preparedness and readiness related to DEs and developing the Organization’s capacity to coordinate the international public health response to a DE.

    Preparedness

    Preparing for deliberate events (DEs) is an integral part of developing and updating national emergency preparedness and response plans. WHO advises Member States to 1) strengthen public health surveillance and preparedness activities and to 2) link public health and security authorities to prepare for possible DEs, with an emphasis on:  

    • evaluating and identifying gaps in national preparedness and readiness, as well as national capacities to manage risks posed by deliberate exposure to hazardous materials, disinformation or cyberattacks. This could be done by using the section dedicated to DE (1) of the National Self-Assessment toolkit (NSAT), which provides a baseline measurement of national capacity and capabilities related to DEs. NSAT is typically used in preparation for a Joint External Evaluation (JEE) or as part of a National Action Plan for Health Security (NAPHS);
    • developing training material packages for online (OpenWHO course series) and in-person sessions;
    • identifying and recommending actions to fill gaps in readiness by conducting DE simulation exercises in collaboration with relevant partners;
    • developing national, sub-national or local stockpile systems to provide deployable pharmaceuticals, supplies and equipment to support rapid national response operations; and 
    • putting in place national protocols or formal agreements to work with partners and benefit from international assistance for responses.

    WHO response

    Similar to non-deliberate event response, WHO experts can be deployed at country, regional and global levels to support the DE response upon the request of the affected Member State(s). Specific WHO response activities specific to DEs include:  

    • working with international or national partners and laboratories to characterize the nature, scope, and impact of the DE;
    • offering targeted training to public health and frontline responders;
    • facilitating the identification and acquisition of necessary response materials (such as personal protective equipment or medical countermeasures) and providing medical countermeasures in certain circumstances; and
    • coordinating additional international expert support through WHO Networks including the Global Outbreak and Response Network (GOARN), WHO Collaborating Centres, or the UN Humanitarian Emergency Cluster system. WHO can join the United Nations Secretary-General’s mechanism (UNSGM) in very specific cases.

    The nature and cause of an event may not be clear when the response is initiated and may or may not be conclusively determined over time. WHO does not have mandate to lead or investigate an attribution process, though WHO may collaborate with and support other entities whose role is to determine the identity of the perpetrators of a DE.
