Most of the new human cases are spread throughout the state though Burleigh, Cass and Richland counties did have the most positive with seven, 13 and 9 respectively.
Grand Forks County had three human West Nile virus cases before the increase and has not reported any new cases, although 10 mosquito pools have tested positive for the virus. However, Ramsey County, the other county in the region with West Nile virus cases, reported no cases as of Aug. 31 and now has two.
Minnesota reported 49 human cases and 13 infected blood donors who had no symptoms.
In the northwest region, Polk County reported four cases, Marshall County one and Roseau County one. The Roseau case is the only new one since Sept. 3.
