Answer

In the Americas, dengue epidemics were rare post war because Aedes mosquitoes had been eradicated from most of the region through coordinated vector-control efforts. Systematic spraying was halted in the early 1970s because of environmental concerns. By the 1990s, A aegypti mosquitoes repopulated most of the countries in which they had been eliminated.
