Unpredictable and Difficult to Control ? The Adolescence of West Nile Virus
Lyle R. Petersen, M.D., M.P.H., and Marc Fischer, M.D., M.P.H.

Disturbingly unpredictable, disagreeable, and difficult to control ? West Nile virus, first identified in the United States in 1999, has entered adolescence. In this year's tally, 3142 cases of West Nile virus disease in humans in 45 states had been reported to the Centers for Disease Control and Prevention as of September 18, 2012, including 1630 cases of resulting neuroinvasive disease (meningitis, encephalitis, acute flaccid paralysis) and 134 deaths. Almost 40% (1225) of all cases were reported in Texas, mostly in Dallas and surrounding counties (see maps Incidence of West Nile Virus Neuroinvasive Disease.). To judge from past reporting trends, these figures suggest that this year's West Nile virus outbreak will be among the largest ever recorded.
