The Minnesota Department of Health says a Dakota County resident is the first human West Nile case in the state, but the person may have contracted the disease while traveling.

In North Dakota, the first human case of West Nile Virus has been identified in Grand Forks County. Health officials urge residents to take precautions to avoid being bitten by mosquitoes. Human cases of W-N-V tend to peak in August as populations of the Culex tarsalis mosquito become more prevalent. Statewide five cases have now been confirmed.Health officials did not specify where in Grand Forks County the case was identified. In the city of Grand Forks health teams have sprayed six times this summer season for mosquitoes.

In 2016 the city launched 22 ground attacks. Trap counts have been on the low side with the highest occurring August 1st when the reading hit 14. In 2005 the daily trap count reached 438.

Many people infected with W-N-V never develop symptoms. Some may experience symptoms ranging from fever…headache…body aches…and rash. In some cases the mosquito-borne illness can be fatal.
