Excerpted from July 21, 2003 ProMED-mail posting (Id: 20030721.1782): Date: Fri 18 Jul 2003 Source: Radio Canada, nouvelles (trans. from French and edited by ProMED Moderator MPP) http://radio-canada.ca/nouvelles/Index/nouvelles/200307/18/005-nil-nouveau-brunswick.shtml FIRST DETECTION OF WNV IN NEW BRUNSWICK, CANADA Results of analyses conducted in New Brunswick have confirmed the presence of WNV in the Province, according to the Chief Medical Officer for Public Health, Dr. Wayne MacDonald in Fredericton. The carcass of an infected bird, a crow, was found in New Maryland in the periphery of Fredericton [approximately the 67th meridian]. The Ministry of Health and Welfare of the province declared they will intensify surveillance activities in a 50-km sector around New Maryland, but they do not have sufficient supplies of insecticide at the current moment. The Ministry of Health and Welfare require the population to report the presence of carcasses of crows, corbels, Canadian titmouses, and bluejays through a toll-free line for WNV in the province. "Now that we know that WNV is present in the province, it is all the more important that residents take necessary precautions to avoid mosquito bites" said Dr. Wayne MacDonald in an official statement. The risk of suffering disease caused by WNV is relatively low and the risks of serious consequences from disease are even lower, affirmed the doctor, emphasizing that it was important to avoid mosquito bites. [WNV-L Moderator's Note: In 2002 WNV was detected in 5 Canadian provinces (Manitoba, Nova Scotia, Ontario, Quebec, Saskatchewan), as well as in an "imported" human case in Alberta that was likely acquired while travelling in the US. While it had not previously been detected in New Brunswick, it has been detected further east, at sites in Nova Scotia close to the 65th meridian.
