In the News: West Nile Virus update
What’s On Your Mind?: 

According to Dr. Lyle Petersen, Director of CDC’s Division of Vector-Borne Infectious Diseases: "As of September 4, 2012, 48 states have reported West Nile virus infections in people, birds, or mosquitoes. The only states not reporting West Nile activity are Alaska and Hawaii. Forty-four states have reported at least one human case. A total of 1,993 cases of West Nile virus disease in people, including 87 deaths, have been reported to CDC. Of these, 1,069 (54 percent) were classified as neuroinvasive disease (such as meningitis or encephalitis) and 924 (46 percent) were classified as non-neuroinvasive disease. This week numbers represent about a 25 percent increase over last week.
The 1,993 cases reported thus far in 2012 is the highest number of West Nile virus disease cases reported to CDC through the first week in September since West Nile virus was first detected in the United States in 1999.
As was true last week, over 70 percent of the cases have been reported from the following six states: Texas, South Dakota, Mississippi, Oklahoma, Michigan, and Louisiana. And nearly 45 percent of all cases have been reported from Texas."

CDC expect the West Nile virus transmission to continue until October in most regions of the country. CDC provided the following health promotion guidelines:

> Wear insect repellents when you go outdoors.
> Wear long sleeves and pants during dawn and dusk.
> Install or repair screens on windows and doors.
> Use air conditioning, if possible.
> Empty standing water from items outside your home such as gutters, flowerpots, buckets, kiddie pools, and birdbaths.
> Support your local community mosquito control programs.
