For the second time in two months a mosquito sample from Birch Grove Park in Northfield has tested positive for West Nile virus, according to the Atlantic County Division of Public Health.
Birch Grove Park was one of three sites where samples tested positive for the virus in 2011 and again in July of this year, the first positive sample of the 2012 season. Since then another positive sample and an infected bird were collected in Galloway.
According to the Centers for Disease Control every state has reported West Nile virus in mosquitoes, birds or humans this year with the exception of Alaska and Hawaii. The 2,636 cases reported thus far in 2012 is the highest number of West Nile virus disease cases reported to CDC through the second week in September since 2003. Two thirds of the cases have been reported from six states (Texas, Louisiana, South Dakota, Mississippi, Michigan, and Oklahoma) and 40 percent of all cases have been reported from Texas.
