The number of West Nile infections this year is nearly double the amount from this time last year, but fewer people have died
SO FAR THIS year, 2,923 people have been infected with the virus and 54 have died. Last year at this time, there were 1,641 human cases and 72 deaths, the Centers for Disease Control and Prevention said.
“We are still experiencing the upside of the epidemic curve,” said Dr. Julie Gerberding, CDC director.
Late August through September is considered the peak season for the virus, which is spread by mosquitoes. By the end of 2002, 4,156 people were infected and 284 died in the largest West Nile outbreak in the Western Hemisphere.
Gerberding said the higher number of infections this year may be the result of improved testing methods and earlier testing. She did not explain the lower death rate, but health officials have said this year’s reported cases tend to be less severe, in part because people with milder symptoms are more likely to be tested.
Colorado has been the hardest hit this summer, with 973 human cases. Thirteen of the country’s deaths were in Colorado, followed by 10 in Nebraska.
