The Mesa County Health Department has elevated the risk of West Nile Virus in more locations in the county. Another four mosquito pools have tested positive for the virus. The pools that tested positive are in Loma, Mack, the Redlands near South Camp and South Broadway, at 12th Street and Horizon Drive and near 24 1/2 and H Roads.
After detecting the new pools health officials say the risk of infection is being raised to moderate. So far in Mesa County there have been three human cases of West Nile illness and one positive test on a horse.
The health officials at the statewide level are reporting 18 human cases, but that number is expected to rise.
West Nile is spread through mosquito bites. Officials advise residents to use insect repellant that contains Deet and eliminate standing water on their properties.
