Related to biological transmission: vector transmission
biological transmissionIndirect vector-borne transmission of a pathogen, in which it undergoes biological changes within the vector before transmission to a new host. Biological dose measurements are used to identify exposure: the presence of a contaminant or metabolites in specimens—e.g., blood, hair, or urine—confirm exposure, and can be an independent variable in evaluating the relationship between the exposure and any adverse health effects.
