West Nile Virus: Remember '4 Ds,' Says Broomfield Health Dept.

BROOMFIELD, CO – Mosquitos are out in the summer weather, just like humans. To that end, the Broomfield Health Department urges residents to remember the "Four Ds" during West Nile virus season:

• Drain standing water around the house since that's where mosquitoes breed. Be sure to empty old tires, cans, flowerpots, clogged rain gutters, rain barrels, wading pools, and other toys where puddles can occur.
• Dusk and Dawn are when mosquitoes that carry the virus are most active, so limit outdoor activities or take precautions to prevent mosquito bites.
• DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide the best protection. Follow label instructions.
• Dress in long sleeves and pants to keep mosquitoes from biting. Spray clothes with insect repellent for extra protection.

So far, no human cases of West Nile virus have turned up in Colorado in 2018. Broomfield did not report any cases of West Nile last year, although the Colorado Department of Public Health and Environment reported 68 cases statewide. In 2003, Colorado reported its largest number of West Nile victims, with 2,947 cases.

"Protecting yourself from mosquito bites is the number one way to avoid mosquito-borne illness," said Jason Vahling, Broomfield's public health director in a statement. "Use an effective insect repellent, wear protective clothing or stay indoors when mosquitoes are active, and mosquito-proof your home."

Broomfield's Mosquito Control Programis contracted through Vector Disease Control International. The company regularly monitors mosquito populations and West Nile virus activity to determine if, when, and where interventions are needed, the city health department said in a statement.

About West Nile virus:

Most people who are infected with West Nile virus don't have symptoms. About 20 percent have flu-like symptoms, and fewer than one percent develop a serious, potentially deadly illness. People over age 60 and those with certain medical conditions are at greater risk of serious illness. See a health care provider if you develop severe headaches or confusion after being bitten by mosquitoes.
