Spatio-temporal variability in the transmission of dengue in Buenos Aires City
Cases of dengue detected in Buenos Aires City between 1999 and 2000 confirmed the possibility of epidemic outbreaks. The activity of its vector Aedes aegypi was monitored to study the spatial and temporal risk of dengue transmission. Adult oviposition activity of Aedes aegypti showed an heterogeneou...
