West Nile virus still circulating in Larimer County: protect yourself against mosquito bites

Though it may seem like autumn has arrived along with cool nights, the Larimer County Department of Health and Environment reminds you that West Nile season is still very much with us.

Since July 1, a total of eight cases of West Nile virus infection have been confirmed in Larimer County. Out of those eight, six had West Nile fever, and one was discovered to have West Nile infection when being screened to donate blood. The eighth person was hospitalized with West Nile encephalitis, but is now recovering at home.

“This should remind all of us that West Nile Virus is still a threat and that it can make even a healthy person very sick, ” said Dr. Adrienne LeBailly, director of the Health Department. “ It’s wise to continue to use an effective mosquito repellent throughout this holiday weekend and until the first frost. ”

In 2009, there were a total of 25 confirmed cases of West Nile illness in Larimer County. Sixteen of the 25 were reported after September 1.
