Close-up of mosquitos in petri dish\u003cbr/\u003eHealth authorities in the U-S are being forced to take seriously the spread of the West Nile virus - with news of the first reported death this year and new cases being reported in a growing number of states.\u003cbr/\u003eA 71-year-old Atlanta woman, Blanch Hill, died on August 11, the first human death in the United States this year attributed to West Nile, which has been blamed for nine deaths in New York and New Jersey since 1999.\u003cbr/\u003eA day before Hill died in Atlanta, New York City recorded its first human case of West Nile this year in a 73-year-old woman.\u003cbr/\u003eMeanwhile in Canada, a dead blue jay bird found in Ontario has initially tested positive for the West Nile virus.\u003cbr/\u003eCanadian health officials say that the disease may have spread north to the Toronto area, but final results are not due for another two weeks.\u003cbr/\u003eThe virus was first spotted in the Western Hemisphere in 1999, when 59 people were hospitalised and seven died.\u003cbr/\u003eNow just two years later it is found along the eastern seaboard of the United States and appears to be spreading at an alarming pace.\u003cbr/\u003eThe mosquito-borne virus caught scientists and medical authorities by surprise, initially causing panic.\u003cbr/\u003eAlthough deadly to the elderly, the young, or those with impaired immune systems, symptoms of the West Nile Virus represent more of a nuisance than anything else to most healthy people.\u003cbr/\u003eBut scientists are warning that the chances of another exotic virus moving to the United States are quite high, and the next one could be much more devastating.\u003cbr/\u003eScott Shone is a mosquito hunter. He is chasing members of the 14 mosquito species that are known to possibly carry West Nile Virus.\u003cbr/\u003eMosquitos can carry the virus from birds to humans and other animals.\u003cbr/\u003eHe is hunting his quarry in the epicentre of the 2001 outbreak of the virus - the Maryland city of Baltimore.\u003cbr/\u003eMaryland leads the nation in the number of dead birds testing positive for the virus this year, with more than eighty birds testing positive in north-east Baltimore alone.\u003cbr/\u003eThis could explain the mysterious disappearance of a large crow population in the neighbourhood of Clifton Park, Baltimore.\u003cbr/\u003eShone's searches range from parkland to residential back yards.\u003cbr/\u003eWith his mosquito traps he can catch the mosquitos that carry the West Nile Virus and track the movement of the virus.\u003cbr/\u003eAfter being collected from the traps, the mosquitos are sent to a Department of Agriculture laboratory in Annapolis for sorting.\u003cbr/\u003eWorking with other states and the Federal government, these researchers are looking at densely-populated areas to determine the relative population size of the mosquitos and their species type.\u003cbr/\u003eMaryland's Chief Mosquito Control Officer, Cy Lesser, agrees that his team was caught by surprise when they discovered in May that the virus had wintered in the area, forcing them to intensify their detection efforts. \u003cbr/\u003eAfter being sorted into species, the trapped mosquitos are sent to Maryland's State Health Laboratories where they are further analysed to see if they are carrying West Nile Virus or other viruses that could harm humans.\u003cbr/\u003eThe labs test both mosquitos and dead birds for the presence of the virus.\u003cbr/\u003eThe researchers take a portion of the brain from the bird, or in the case of the mosquitos the whole body, and use a special process to extract any genetic material present from viruses.\u003cbr/\u003eThis is then run through an electronic scanning device to test for type.\u003cbr/\u003eLast year, 21 human West Nile cases were reported, two of them fatal, according to the U-S Centre for Disease Control and Prevention. \u003cbr/\u003eBut Dr Myers of the Maryland Department of Health believes that the spread of West Nile Virus to North America is a timely reminder for the government to raise their awareness of possible new viruses, especially with the emerging threat of biological terrorism.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv
