Where are Aedes found?
Aedes is a genus of mosquitoes originally found in tropical and subtropical zones, but now found on all continents except Antarctica.
What are Aedes mosquitoes attracted to?
Among the odors tested, 3-methyl-1-butanol, 6-methyl-5-hepten-2-one, hexanoic acid, 1-octen-3-ol, lactic acid and ammonia have been shown to attract Aedes female mosquitoes with fresh and/or incubated sweat or with incubated sweat liquid [2, 6, 8, 13, 15,16,17,18,19,20].
Can Aedes cause death?
Dengue is spread by several species of female mosquitoes of the Aedes genus, principally Aedes aegypti. The virus has five serotypes; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others….

How does Aedes aegypti contribute to the spread of disease?
The spread of Aedes mosquitoes, especially A. aegypti and A. albopictus, which are native to Africa and Asia, is suspected of facilitating the uptake and transmission of pathogens by endemic Aedes species. Infected humans may also play a role.
How many species of Aedes mosquitoes are there?
Aedes, genus of more than 950 species of mosquitoes (order Diptera), some members of which are serious biting nuisances and vectors of disease, sometimes transmitting potentially deadly pathogens (disease-causing organisms) to humans and other animals.

On Madeira Island, Ae. aegypti is active throughout the year, with a peak in abundance from August to October [26]. Aedes aegypti prefer mammalian hosts [27] and will preferentially feed on humans, even in the presence of alternative hosts [28].
Where are there outbreaks of Aedes albopictus virus?
Local outbreaks have also been reported in parts of Hawaii, Florida, and Texas. People get infected with a virus (like Zika, dengue, or chikungunya).
