Most biological agents are typically dispersed as what?

Biological agents are most commonly dispersed as aerosols due to their effectiveness in reaching and infiltrating various environments. When released as aerosols, these airborne particles can be easily inhaled, allowing pathogens to access the respiratory system of humans or animals quickly. This method of dispersion maximizes the potential for exposure within a population, making it a preferred mechanism for many harmful biological agents.

While biological agents can also be found in other forms such as liquids, granules, or gases, their use in aerosol form is particularly concerning for public health and safety because of the efficiency with which they can spread and infect hosts. The characteristics of aerosols, such as small particle size and ability to remain suspended in the air for extended periods, contribute significantly to their effectiveness as a delivery method for biological threats.
