The video aims to contribute to a better understanding of the dispersal of two species of mosquitoes across the continents and their role as transmitters of viruses, giving a special focus on dengue, which in recent years has caused several epidemics in many tropical countries.
These species are Aedes aegypti, vector for dengue and urban yellow fever, and Aedes albopictus, which, besides dengue, transmits the arbovirus of the Japonese Encephalitis.
Mosquitoes of the first species come from the African continent; mosquitoes of the Aedes albopictus, also known as Asian tiger mosquito, are natives of Asia and Oceania.
In the past, with colonization, and more recently, globalization, mosquitoes and pathogens have been more easily disseminated, causing deaths and, therefore, modifying the sanitary conditions and habits of the populations in countries of tropical and subtropical climates.
With global warming, their territories tend to expand, representing a threat for the public health of other populations, especially in areas of great urban concentrations, particularly in areas of disordered human occupation. This is why it’s important to know these species to contribute to fight their proliferation.
The documentary is composed of real and virtual images of mosquitoes, showing the continent of origin, their distribution throughout the world, their morphological characteristics, their eating habits, their feeding mechanisms, their breeding and the environment they live in.
