A vector is an animal capable of carrying a disease organism or parasite from one host to another. Vectors are insects, ticks, rats, mice, birds and other animals that transmit disease-producing organisms to humans.
Most vectors are extremely mobile and often cause the greatest hazard or discomfort away from their breeding source. Each has a unique life cycle and most of them occupy different habitats.
The vector problem in Marion County is largely a human associated problem resulting from agricultural endeavors, increasing population, and urbanization. Additional problems will occur as urbanization continues into area of high vector populations and as recreation and conservation areas expand.
