Mosquitoes and the West Nile Virus
The mosquito may seem akin a fairly benignant insect; however, it can be extremely deadly when it is a carrier of the westward Nile virus (WNV). The West Nile Virus is a deadly microscopic organism that has recently pervade byout the world. This virus is unique in that it can vitiate duple species. The West Nile virus is not only able to infect humans, but animals like domestic fowls and horses. It is channeliseted throughout the different species through mosquito bites. Mosquitoes that are infected with the illness bite organisms, which then transmit the sickness to them. The West Nile virus can have major negative impacts on the biodiversity of ecosystems and on the well being of society.\nThe West Nile virus was start notice in the African area of Uganda in 1937. Since the 1950s it has pass out throughout Africa, Europe, Australia, and the Middle East. In 1999 scientists discovered the virus for the first time in the westerly hemisphere when it killed hundreds of birds in the nor-east United States. The disease has since spread to horses and humans. The Culex tarsalis mosquito is the most rough-cut carrier of the disease. It causes flu-like symptoms, especially febrility and headaches. These symptoms usually appear at heart 3 to 15 days of contracting the disease. Since 1999, 23,000 Americans have contract the disease and 962 have flush itd; 3 to 15 percent of quite a little who contract the virus die from it.\nThe West Nile virus to begin with affects birds, especially inexorable jays and crows. The dec in creation of these birds has had ascetic effects on the biodiversity of ecosystems. near all crows that contract the disease die because of it. The crow population has decreased by 45% since 1999. In the case of the moody jay its foremost role in ecosystems is to alert different bird species when a predator such as a huckster or an eagle is approaching. This helps otherwise bird species such as sparrows and warblers esc ape predators. With the decline of blue jays ...
