Dengue is a mosquito-borne viral infection, contracted through a bite of Aedes aegypti and Aedes albopictus mosquitoes carrying the dengue virus. These mosquitoes can lay eggs in spaces or containers that can hold stagnant water – bottle caps, dish dryers, gutters, trash cans, old rubber tires, and even plant axils with stagnant water can be nests for dengue-infected mosquitoes.
