West Nile virus prevention
Health officials have recommended that residents practice the "Four D's" in order to reduce the risk of being bitten and infected by Culex mosquitoes carrying the West Nile virus:
Apply an effective mosquito repellant, such as Deet, to exposed skin and clothing.
Drain any standing water that can provide breeding places for mosquito. Use mosquito larvicides in areas of standing water that cannot be drained. Avoid over-watering lawns, since mosquitoes can breed in very small amounts of water.
From Dusk to Dawn,avoid being outside. That's when mosquitoes are most active.
Dress in long sleeves, pants and a hat in areas where mosquitoes are active.
Boulder County and Weld County health officials are reporting new human cases of West Nile virus.
Boulder County Public Health's weekly zoonotic disease report has listed two new cases as of Aug. 23, a meningitis case from Longmont and a person from Lafayette with fever symptoms.
Boulder County now has confirmed a total of four human cases. None of those people currently is hospitalized.
Weld County's Department of Public Health and Environment reported Tuesday that seven Weld County residents have now been confirmed to have been infected by the West Nile virus this summer, including a 63-year-old man hospitalized with a neuroinvasive infection — with the infection having gotten into the brain or spinal cord.
Details were not immediately available about where in Weld County those seven individuals live. Weld health officials said two possible additional cases of the virus in that county are also being investigated.
Cheryl Darnell, lab manager for the Weld Health Department, said that while there's been an overall decline in West Nile virus activity over the past two weeks, "the vector index is still high and people continue to become sick with the virus."
The vector index is a formula used to determine the risk for human infection, based on tests of trapped mosquitoes.
