Introduction
Bioaerosols exposure and potential impact on human health is a growing concern. Bioaerosols are assemblies of particles of variable biological origin (bacterial, viral, or fungal) suspended in the air and capable of initiating an infectious process in a susceptible host. They usually consist of a mixture of mono-dispersed and aggregate cells, spores, or viruses, carried by other materials, such as respiratory secretions. With rapid desiccation, the resultant smaller aerosols can remain airborne longer, while larger aerosols may initially fall out and then become re-suspended after desiccation.
