ResumoThis chapter discusses nine mosquito-borne viral encephalitides in the context of their significance to world public health: Japanese, Murray Valley, eastern equine, western equine, Venezuelan equine, St. Louis, La Crosse, Jamestown Canyon, and Rocio encephalitis. This chapter focuses on those mosquito-borne arboviruses that are neurotropic and that occur with some frequency over large geographic areas that are heavily populated. Two emerging diseases, Jamestown Canyon encephalitis and Rocio encephalitis, are also included because their medical importance is expected to increase as additional investigations are made. The reports cited in the chapter, indicating the marked effects of larval nutrition on vector infection and ability to transmit, clearly demonstrate that physiological stress must ultimately be considered in future vector competence investigations. It is easy to obtain wing-length measurements of adult females collected as field-bred pupae as well as adults obtained in biting collections. These wing-length data provide the basis for dietary manipulation that permits the routine laboratory production of adult females that are of a field-relevant size and physiological condition. Prevention of human encephalitis through vaccination for mosquito-borne neurotropic arboviruses has not been discussed because, with the exception of Japanese encephalitis virus, no widespread use of such a vaccine has been made.
