FORT COLLINS, Colo. -- Mosquitoes trapped in the northeast and southeast sections of Fort Collins tested positive for West Nile virus, the first such cases this season, the city said Tuesday.

The measure of infected mosquitoes is 0.03 in the city, and it must be 0.75 in any of the four zones plus two confirmed human cases before the city will consider adjusting the vector index.

Larimer County has a lower threshold and might initiate an application earlier bases on the recommendation of the director of the Health and Environment Department.

Symptoms of West Nile range from none to very serious. The city is encouraging residents to drain any standing water; wear lightweight, long-sleeved shirts and long pants while outside; apply insect repellent to exposed skin; and limit time outdoors at dawn and dusk.
