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.
