The city of McMinnville plans to step up its mosquito spraying efforts due to a warning from the Centers for Disease Control about the West Nile virus.According to the CDC, 1,118 cases of the West Nile virus have been reported thus far in 2012, which is the highest number of reported cases through the third week in August since West Nile virus was first detected in the United States in 1999.This year, 47 states have reported West Nile virus infections in people, birds, or mosquitoes. Of the 1,118 cases in people, 41 deaths have been reported to CDC. Of the cases, 629 (56 percent) were classified as neuroinvasive disease (such as meningitis or encephalitis) and 489 (44 percent) were classified as non-neuroinvasive disease.Approximately 75 percent of the cases have been reported from five states (Texas, Mississippi, Louisiana, South Dakota, and Oklahoma) and almost half of all cases have been reported from Texas.Despite the fact Tennessee is not high on the list of reported case, the alarming numbers have prompted McMinnville Mayor Norman Rone to ask McMinnville Public Works Department to step up its spraying for mosquitos.“Those numbers are very concerning to me,” said Rone. “We need to be pro-active in this situation.
