Back in 2002 and 2003, West Nile virus, a malady carried by mosquitoes, swept through the United States, claiming nearly 3,000 cases and some 260 deaths.
Now, statistics from 2009 show the virus, which can cause symptoms from fever to paralysis and coma, has clearly waned. Federal health officials say there were just 33 related deaths last year, notes The Associated Press.

Still, the virus, is active. Two cases have been logged in Colorado so far this year, including a 39-year-old woman from the small northern Colorado town of LaPorte who became ill in early June. The woman is still recovering at home, reports the Loveland Reporter-Herald, which points out that the Culex variety of mosquitoes, which transmit the disease, typically begin popping up in July.
Last year, 103 cases and three deaths were attributed to West Nile virus in Colorado.
