CRUZ PINEDA, Carlos Alberto  and  CABRERA CARMENATE, María Virginia. Entomological-ecological characterization of positive cases and suspected cases of West Nile virus in Sancti Spiritus province, Cuba. Rev Cubana Med Trop [online]. 2006, vol.58, n.3, pp. 0-0. ISSN 1561-3054.

A descriptive study on Culicidae species present in the habitats of the first positive cases and suspected cases of being affected by West Nile virus in Cuba and the conditions of its main breeding sources was presented. The samplings were taken in a radius of 1 000 meters from the houses of 2 positive cases and 19 suspected cases. Sixteen Culicidae species of which 6 are associated to the virus transmission in North America, mainly Culex quinquefasciatus Say, 1023 and Culex nigripalpus Theobald, 1901.  Among the fundamental risk factors are the inadequate environmental condition of permanent breeding sites (pits, ditches and streams) as well as unprotected water tanks inside the house and in the perimeter of the house.

Keywords : West Nile fever; Culicidae; arbovirosis; Culex quinquefasciatus; Sancti Spiritus; Cuba.
