ABSTRACT
Arthropods play an important, and in some cases a determinant role, in the transmission of some infections. The epidemiology of these infections is closely related to the ecology of the arthropod vector, and hence the most effective measures for the control of these infections often relate to the control of the vector. The arthropod vector introduces a further dimension to the complex host-parasite interrelationship, and for some of these infections, a fourth factor is added when there is a non-vertebrate animal reservoir. Arthropod vectors of importance include various species of flies, mosquitoes, fleas, ticks and mites.
