Grand Forks County reported its first human case of West Nile virus Thursday.
Until now, the mosquito-transmitted virus had only been detected in insects and birds.
Grand Forks Public Health officials announced the virus had been found in the area earlier this summer.
West Nile is most common during mosquito season -- throughout the summer and fall -- and people usually are infected after bitten. The Centers for Disease Control and Prevention reported only one of five infected people typically will show symptoms, those usually just being a fever. The CDC further reported just one of about 150 cases will end in death.
As of Wednesday, the state Department of Health reported it has identified 38 North Dakotans this summer with West Nile virus and no fatalities.
Of the 62 patients in North Dakota last year, the health department reported two deaths.
Everyone is susceptible to West Nile, but a Thursday news release from the city of Grand Forks said the disease more severely affects people with compromised health and residents older than 50.
The city advised residents to avoid the disease by avoiding mosquito bites. Additionally, the release said residents should eliminate any access to standing water, wear sleeves whenever possible, stay inside when mosquitoes are most active during sunrise and sunset, and use insect repellent with DEET.
