What are general indicators of a biological or chemical attack?

The presence of dead or sick animals is a significant indicator of a biological or chemical attack for several reasons. Animals can be highly susceptible to various pathogens and toxins used in such attacks. For instance, certain biological agents, like anthrax or plague, can cause rapid mortality in wildlife or livestock, serving as an early warning sign for affected ecosystems and nearby human populations.

Moreover, the sudden death or illness of animals can indicate the release of hazardous agents into the environment, which could potentially affect human health as well. Monitoring animal health is a crucial part of surveillance in areas where biological or chemical attacks could occur, allowing for timely responses to protect both human and animal populations.

In contrast, while floods and storms, high winds and rain, and power outages and blackouts can be disruptive, they do not specifically point to biological or chemical threats. These conditions may lead to secondary complications or hazards, but they lack the direct link to potential biological or chemical warfare indicators that the health status of animals presents.
