Mesa County confirms West Nile case
July 30, 2014
The Mesa County Health Department on Monday reported lab confirmation of this year's first West Nile virus in a resident of Mesa County.
The incubation period for West Nile Virus is about five to seven days, which means it usually takes that long for symptoms to appear after a person is infected.
Colorado on Monday had five human cases of West Nile Virus, including Mesa County's, and no deaths.
The Mesa County Health Department urges residents to use protective measures against West Nile Virus:
• Use insect repellent that contains DEET, picaridin or oil of lemon eucalyptus.
• Dress in long sleeves and pants when in areas where mosquitoes are active.
• Drain standing water on property.
• Avoid being outdoors at dusk and dawn; this is when mosquitoes are most active.
Of people infected with West Nile virus, 80 percent show no symptoms. Symptoms can include headache, fever, body aches, nausea, a rash and swollen lymph nodes. Severe illness such as meningitis and encephalitis can occur.
