Vector control or the management of disease-spreading species of mosquitoes is a large concern among. Examples of vector-borne diseases include Dengue fever West Nile Virus Lyme disease and malaria. Choose from 500 different sets of vector borne flashcards on Quizlet.

Vector-borne diseases can be treated and even prevented by interrupting the vector-mediated transmission between the infected host and the susceptible person or animal. Vector transmission is the other strategy used by protozoan parasites which inhabit the blood or internal tissues within its host.
