A pool of mosquitoes collected recently from Grand Forks has been identified as having West Nile virus.

Todd Hanson, Mosquito Control Supervisor for the City of Grand Forks, says the North Dakota Department of Health recently notified them of a human case of West Nile.

The cities of Grand Forks and East Grand Forks urge citizens to take extra precautions to avoid being bitten by mosquitoes.

Hanson tells WZFG that his department operates as if the virus is always present and therefore will not be making major changes to the daily operations of mosquito control.

The mosquito most common for transmitting West Nile virus is the Culex tarsalis. Hanson says the mosquito is most active just before sundown and throughout the night into the early morning hours.
