Mosquitoes and the West Nile Virus

The mosquito may seem like a fairly harmless raspberry louse; however, it send packing be exceedingly deucedly when it is a toter of the western hemisphere Nile Virus (WNV). The due west Nile Virus is a deadly microscopic organism that has deep spread end-to-end the world. This computer virus is unique in that it potbelly infect multiple species. The westmost Nile virus is not plainly able to infect humans, scarcely animals like birds and horses. It is transmitted throughout the different species through mosquito seize with teeths. Mosquitoes that are infected with the sickness bite organisms, which then transmit the infirmity to them. The West Nile virus can have major ban impacts on the biodiversity of ecosystems and on the hale being of society.\nThe West Nile virus was first notice in the African country of Uganda in 1937. Since the 1950s it has spread throughout Africa, Europe, Australia, and the Middle East. In 1999 scientists discovered the virus for the first prison term in the Western hemisphere when it killed hundreds of birds in the northeast linked States. The disease has since spread to horses and humans. The genus Culex tarsalis mosquito is the most common holder of the disease. It causes flu-like symptoms, especi everyy fever and headaches. These symptoms ordinarily appear within 3 to 15 days of bosom the disease. Since 1999, 23,000 Americans have contracted the disease and 962 have frighten offd; 3 to 15 percent of people who contract the virus die from it.\nThe West Nile virus primarily affects birds, especially blue jays and crows. The decline in population of these birds has had severe personal effects on the biodiversity of ecosystems. Almost all crows that contract the disease die because of it. The crow population has lessen by 45% since 1999. In the case of the blue jay its best role in ecosystems is to spanking different bird species when a predator such as a hawk or an eagle is approaching. This helps ot her bird species such as sparrows and warblers dodge predators. With the decline of blue jays ...
