Media and scientific attention has recently been focused on the spread of a Virus know as Zika. The virus is spread by the Aedes Aegypti, a mosquito that inhabits tropical, subtropical, and temperate regions. The Aedes Aegypti’s origin is in West Africa, and its trans-Atlantic spread has occurred from the 17th century to the modern day by stowing away on ships. Aedes Aegypti is strongly adapted to live among large human populations, surviving and proliferating through any body of water no matter how big or small. Researchers have found that Aedes Aegypti prospers in dark and wet cargo holds of ships, undoubtedly contributing to its spread throughout the tropical and sub-tropical regions in the last four hundred years (Guagliardo et al, 1). Initially, Aedes Aegypti was know to spread Yellow Fever, and because of this was subject to an eradication program in order to cut down on the spread of the disease (Levine, 1). Today Aedes Aegypti has recolonized much of the area it initially inhabited, ranging from the southern United States and throughout Central and South America. With its return came new viruses including Zika, Dengue, and Chikungunya (CDC, 5). After the mosquito feeds it will lay eggs in any body of water, often spreading the eggs over a large area, this process can take place five or more times throughout a female’s two-week lifecycle. Eggs develop and hatch over the course of two days in tropical environments, but have the ability to survive for months (Kaufman,…
