A human case of West Nile virus has been reported in Nebraska.
Health officials there say a man in his 50's tested positive for the virus, which is transmitted by the bite of an infected mosquito.
The county involved received notice of the test results earlier this week.
There have been two other confirmed human cases of West Nile virus in Nebraska this year - in Hamilton and Butler counties.
State health officials say West Nile activity is increasing statewide.
People should use mosquito repellent, wear long sleeves and take other precautions when outside.
West Nile virus has flu-like symptoms.
Symptoms of the more serious West Nile encephalitis include inflammation of the brain and paralysis.
The disease can be fatal.
