TROYES R, Lucinda; VILLEGAS B, Zoila  and  TROYES R, Mario. Expansión del Aedes aegypti a localidades rurales de Cajamarca. Rev. perú. med. exp. salud publica [online]. 2006, vol.23, n.3, pp.163-167. ISSN 1726-4634.

Objectives: Determine the presence, magnitude and spread of Aedes aegypti in rural locations of the Jaen and San Ignacio provinces, department of Cajamarca. Materials and methods: Cross-sectional study conducted between April and May 2004 in 21 (100%) rural locations alongside the Jaen-San Ignacio road and on the road itself, up to 90 minutes. Artificial containers from 1460 houses were inspected for larvae and adult mosquitos. Aedic indexes from the container and Breteau indexes were derived. Results: The presence of Aedes aegypti was demonstrated in three rural locations of the province of Jaén and in four locations of the province of San Ignacio. Aedic indexes varied from 1,2 and 16,6%. The containers most frequently infested were tires and discarded items capable of holding water. Conclusions: The spread of A. aegypti is reported in one third of the rural locations of the provinces of Jaen and San Ignacio. This spread warrants further study and needs to be taken into consideration when dengue prevention and control strategies are implemented for the Jaen Health Directorate. Outbreaks of dengue fever, dengue hemorrhagic fever, and even urban yellow fever can be reduced if control measures can more accurately target the breeding areas of the vector.
