West Nile virus (WNV) is the leading cause of arboviral encephalitis in the United States. Originally discovered in Africa in 1937, WNV was first detected in the western hemisphere in 1999 in New York City. Since then, WNV has caused seasonal epidemics of febrile illness and severe neurologic disease in the United States. This report summarizes provisional WNV surveillance data for 2006 reported to CDC as of April 3, 2007. During 2006, WNV transmission to humans or animals expanded into 52 counties that had not previously reported transmission and recurred in 1,350 counties where transmission had been reported in previous years. In addition, 1,491 cases of WNV neuroinvasive disease (WNND) were reported in the United States during this period, amounting to a 14% increase from 2005 and the largest number reported since 2003. On the basis of extrapolations from past serosurveys, an estimated 41,750 cases of non-neuroinvasive WNV disease occurred in 2006; of these cases, 2,770 were reported. These findings highlight the need for ongoing surveillance, mosquito control, promotion of personal protection from mosquito bites, and research into additional prevention strategies.
