Mosquito-borne disease
Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by mosquitoes. They can transmit disease without being affected themselves. Nearly 700 million people get a mosquito-borne illness each year resulting in over one million deaths.
Aedes vexans
"A. vexans" is a known vector of "Dirofilaria immitis" (dog heartworm), myxomatosis (a deadly rabbit viral disease), and Tahyna virus, a seldom-diagnosed "Bunyaviridae" virus, which affects humans in Europe, causing a fever which disappears after 2 days, but afterward can cause encephalitis or meningitis. "A. vexans" is the most common mosquito in Europe, often comprising more than 80% the European mosquito community. Its abundance depends upon availability of floodwater pools. In summer, up to 8,000 mosquitoes can be collected per trap per night. "A. vexans" exhibited significantly higher transmission rates of Zika virus than "A. aegypti", and its wide geographic distribution, periodic extreme abundance, and aggressive human biting behavior increase its potential to serve as a Zika virus vector in northern latitudes outside the range of the primary vectors "A. aegypti" and "A. albopictus".
