areas‚ rather than rural‚ unpopulated regions. The dengue virus is passed to humans exclusively by the bite of mosquito in search of a blood meal. This mode of transmission makes the dengue virus an arbovirus (that is‚ one that is transmitted by an arthropod). Studies have demonstrated that some species of monkey can harbor the virus. Thus‚ monkeys may serve as a reservoir of the virus. Mosquitoes who bite the monkey may acquire the virus and subsequently transfer the virus to humans. The disease has

and valves‚ which are overlapping layers of tissue‚ prevent the blood from changing direction. The Praying Mantis‚ an insect classified as an invertebrate‚ has an open circulatory system.
