California's historic drought is partly to blame for the recent rise in West Nile virus infections, public health officials say. There have been 311 cases reported so far, double the number of the same time last year, and the most of any state in the country.
West Nile virus is spread by mosquitoes. They contract the virus when they feed on infected birds, then spread it to the birds they bite next. A shortage of water can accelerate this cycle.
On the Almanac last week, P Kaech reported seeing snow on the top of Mt. Baldy near Crested Butte, and Andrea Lecos noticed that monsoon rains have brought up mosquitoes and other insects. Humans may hate the bugs, but birds are feasting on them.
2012 was a bad year for West Nile Virus in Western Colorado. Mesa, Montrose and Delta Counties accounted for nearly half the confirmed cases in the state. In Delta County, the 22 cases included the death of an 82-year-old man from Orchard City.
Last week, the Delta County Health department reported three additional cases of West Nile Virus among residents. That brings the total number of confirmed and suspect human cases of the virus in the county to 20–most of which have resulted in uncomplicated fever. Most of the reported cases have been in the Delta and North Fork areas, and on Saturday, the town of Hotchkiss sprayed to kill adult mosquitoes. For KVNF and the iSeeChange project, Julia Kumari Drapkin takes a closer look at why mosquitoes and West Nile Virus are thriving in a DROUGHT year and whether community efforts to spray late in the season will pay off.
