Officials from the Adams County Health Department (ACHD) confirmed the first two human cases of West Nile virus (WNV), which were likely contracted from infected mosquitoes in late June. ACHD has begun routine seasonal testing of mosquitoes in Adams County for WNV. Although ACHD has not found the virus in mosquitoes in Adams County so far this year, neighboring counties have reported positive mosquitoes.
Dr. Kelly Weidenbach, Executive Director of the Adams County Health Department, encourages residents to safeguard themselves from WNV.
“The virus is transmitted through mosquito bites,” Weidenbach said. “To protect against it, we suggest using effective insect repellents, wearing protective clothing to minimize exposed skin, or opt to stay indoors during peak mosquito activity.”
Most people infected with West Nile virus don’t have symptoms. About 20% of infected people will have flu-like symptoms, and fewer than 1% develop a serious, potentially deadly illness. People aged 60 years and older and those with certain medical conditions are at greater risk of serious illness. See a health care provider if you develop severe headaches or begin experiencing confusion.
To protect yourself:
- Use insect repellents when you go outdoors. Repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus, or para-menthane-diol products provide the best protection. For more information about insect repellents, visit the EPA’s information webpage. Always follow label instructions.
- Limit outdoor activities at dusk and dawn, when mosquitoes are most active.
- Wear long pants, long-sleeved shirts, and socks in areas where mosquitoes are active. Spray clothes with insect repellent for extra protection.
To mosquito-proof your home:
- Empty water from tires, cans, flowerpots, clogged gutters, rain barrels, birdbaths, toys, and puddles at least once every week.
- Install or repair screens on windows and doors.
To assist Adams County residents, ACHD is distributing free insect repellent wipes containing picaridin at its Westminster clinic (1401 W. 122nd Ave., #200, Westminster), and at various other community outreach events throughout the summer or until supplies last.
