Vector Facts

A vector is any arthropod, insect, rodent or other animal of public health significance capable of harboring or transmitting the causative agents of human disease (e.g. malaria, plague) to humans. Under certain circumstances, insects or other arthropods that cause human discomfort or injury, but not disease, are sometimes referred to as vectors. The vectors that Clackamas County Vector Control District controls are mosquitoes and black flies. This is done by using an Integrated Vector Management (IVM) strategy that includes conducting surveillance, controlling sources and vectors, and public education. The result is a healthier community with a lower risk of disease outbreaks.
