Colorado health officials say the West Nile virus could be back again for another year.
State epidemiologist John Pape (PA'-pee) says the extent of this year's outbreak will vary depending on local moisture and temperatures.
The mosquito-borne disease peaked in Colorado in 2003, with two-thousand-947 cases statewide. Most of those cases were along the Front Range but last year it moved west, with 127 of the 292 statewide cases reported in Mesa County.
West Nile can inflict paralysis, brain damage or death, but 80 percent of those who catch it will show no symptoms.
