Two human West Nile cases in Grand Forks County
GRAND FORKS, N.D. — There are now two human cases of West Nile virus in Grand Forks County, the state Department of Health said Wednesday.
This brings the state total to eight, with one case each in Barnes, Cass, Grant and Stutsman counties and two in Richland County. On Tuesday, the state reported for the first time this year a human case in Grand Forks County.
West Nile virus can cause illness in about one in five people it infects. In 1 percent of those infected, it can affect the brain and cause death. The culex tarsalis mosquito is the primary transmitter. Grand Forks County has increased its spraying since the first West Nile virus case, a dead bird, appeared about three weeks ago.
