Geospatial distribution and detection of dengue virus in Aedes (Stegomyia) aegypti mosquitos in Ciudad Juárez, Chihuahua, Mexico. Salud pública Méx [online]. 2010, vol.52, n.2, pp.127-133.

OBJECTIVE: To determine the distribution of Aedes aegypti in Ciudad Juárez, Mexico and evaluate it as a carrier of the dengue virus. MATERIAL AND METHODS: Mosquitoes were collected using CDC minitraps. Nearest neighbor and K-function were used as geospatial tools. The chi-square test was utilized to evaluate the association between the presence of the vector and sociodemographic variables. Evidence of infection was detected by RT-PCR. RESULTS: A total of 122 female mosquitoes were captured. A tendency in the cluster distribution (R= -1.2995, p= 0.05) of the mosquito was shown up to 4000 m but none of the sociodemographic variables showed significant associations. Seven of the pools tested were positive for DEN-2, ten were positive for DEN- 3, and seven for both serotypes. CONCLUSIONS: This is the first report on the presence of Aedes aegypti mosquitoes infected with dengue in the region, which will enable the promotion of monitoring in order to reduce the probability of occurrence of the disease among the border population.
