KREX News Room
MESA COUNTY, Colo.- The Mesa County Health Department is reporting Friday the first human case of West Nile Virus in an adult Mesa County resident this year.
Symptoms of the virus appear generally five to seven days after a person is infected.
Mesa County began seeing mosquitoes testing positive in early June, a month soon than expected. In mid-July, 50-percent of the mosquito samples collected in Mesa County tested positive for the virus.
This past week, mosquito tests have shown no Culex mosquitoes testing positive for West Nile Virus, though rainy and windy weather can affect results.
Of people infected with the virus, 80 percent show no symptoms. Though symptoms can include headaches, fever, body aches, nausea, a rash and swollen lymph nodes. Severe illness such as meningitis and encephalitis can occur.
