West Nile Virus is a mosquito-borne disease that was first seen in North America in 1999. The most serious manifestation of West Nile Virus infection is fatal encephalitis (inflammation of the brain) in humans and horses, as well as mortality in certain domestic and wild birds. Cases of West Nile Virus in New Mexico have occurred every year since 2003, though decreasing numbers of cases have been reported, from 209 in 2003, 88 in 2004, 33 in 2005 and 8 human cases in 2006. The number of cases increased to 60 in 2007, then fell again to 8 in 2008. West Nile Virus infection in humans occurs seasonally, with the peak of cases in late summer and early fall.
