CDC reports more than 400 West Nile Virus cases last week
As of October 2, 2012, 48 states have reported West Nile virus infections in people, birds, or mosquitoes. A total of 3,969 cases of West Nile virus disease in people, including 163 deaths, have been reported to the Centers for Disease Control and Prevention (CDC).
This is up 424 cases and 16 deaths from one week ago.
Of these, 2,010 (51%) were classified as neuroinvasive disease (such as meningitis or encephalitis) and 1,959 (49%) were classified as non-neuroinvasive disease.
The CDC says the 3,969 cases reported thus far in 2012 is the highest number of West Nile virus disease cases reported to CDC through the first week in October since 2003. Almost 70 percent of the cases have been reported from eight states (Texas, California, Louisiana, Mississippi, South Dakota, Michigan, Oklahoma, and Illinois) and a third of all cases have been reported from Texas.
