Two new human cases of West Nile Virus confirmed in Larimer County

LARIMER COUNTY, Colo. - Two new human cases of West Nile Virus have been confirmed in Larimer County, according to the Colorado Health Department.

That brings the total number of human cases Colorado this year to three. No deaths have been linked to the virus this season.

Some counties are stepping up efforts to prevent more cases.

Crews will be spraying for mosquitoes in six neighborhoods of Erie Wednesday night, including historic downtown and Vista Point Trail.

In Lafayette, there was concern about Waneka Lake.  Crews have been spraying for mosquitoes because tests showed the insects were carrying the virus. But tests done Sunday came back negative and the mosquito count is dropping.

Jefferson County also is seeing more mosquitoes testing positive for West Nile.

Golden says it is treating pools of standing water with larvacide.
