What is the expected ratio of psychological casualties to physically wounded victims following a chem/bio attack?

Following a chemical or biological attack, the psychological impact on survivors can be profound, often resulting in a higher number of psychological casualties compared to physical injuries. The expected ratio of psychological casualties to physically wounded victims is typically greater than 1:1 due to several factors.

Firstly, the nature of chemical and biological agents can elicit extreme fear, anxiety, and panic among the affected population, potentially resulting in post-traumatic stress disorder (PTSD) and other psychological issues. Survivors might not only be affected by physical harm but also by the traumatic experience of the attack itself, leading to a higher prevalence of mental health issues.

Secondly, the psychological consequences can extend beyond those who sustain physical injuries. Individuals who witness the event or are in close proximity may experience significant psychological distress, further contributing to a ratio that exceeds the number of physically injured individuals.

This phenomenon is underscored by historical data and research, which indicate that, in many cases, the prevalence of psychological impact in such scenarios disproportionately affects a larger segment of the population compared to actual physical injuries. Therefore, stating that the ratio of psychological casualties is greater than 1:1 reflects these observed patterns following similar traumatic events.
