Mead Resident is First Human West Nile Virus Case of Mosquito Season

Weld County, CO – An adult resident from the town of Mead is in the hospital for neuro-invasive West Nile Virus—the most serious form of the illness. The Mead resident became ill on July 27 and was hospitalized the next day. Tests results confirmed West Nile Virus (WNV) yesterday. This marks the first human case of WNV in Colorado and Weld County for the 2018 mosquito season.

“The recent wet and increasing hot weather has created the perfect conditions for the Culex mosquito that carries West Nile Virus,” said Mark E. Wallace, MD, MPH, Executive Director of the Weld County Health Department. “It’s extremely important to avoid getting bit by mosquitoes.” Many municipalities have established mosquito control programs, but “the public needs to be vigilant, because this illness has a permanent summer presence in our state,” said Wallace.

West Nile Virus symptoms can appear 3 to 14 days after an infection. Initial symptoms can include fever, headache, nausea and vomiting, muscle aches and weakness and rash, but most infected people don’t exhibit any symptoms. If a person develops symptoms, he or she should see a healthcare professional immediately.

There are no medications to treat or vaccines to prevent WNV infection. Less than one percent of infected people develop a serious, sometimes fatal, neuro-invasive illness.

Health officials recommend following the four “D’s” to prevent mosquito bites:

DRAIN standing water around your house weekly. Remember to drain water from tires, cans, flowerpots, clogged rain gutters, rain barrels, toys and puddles.
DUSK and DAWN are when mosquitoes are most active. Limit outdoor activities and take precautions to prevent mosquito bites during these times.
DEET is an effective ingredient to look for in insect repellents. Other repellents containing picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol are also effective against mosquitoes. Always follow label instructions carefully.
DRESS in long sleeves and pants in areas where mosquitoes are active.
