North Dakota has its first confirmed human case of West Nile virus this year.

The state Department of Health on Friday said the case involves a Grand Forks County woman in her 30s. The patient was not hospitalized because of the illness.

The department last year counted 23 people who tested positive for the mosquito-borne virus. Of those, eight were hospitalized and one died.

State epidemiologist Laura Cronquist is encouraging people to wear mosquito repellent when outdoors during the evening between dusk and dawn.

The virus symptoms include fever, headache, body aches and rash. The department says that most people infected with the virus develop the less severe form of the disease or experience no symptoms at all.
