(KCEN) -- There are now cases of the West Nile Virus in every one of the lower 48 states.
Many are calling it the worst West Nile outbreak ever recorded.
The spraying continued this weekend from Texas to Georgia and up to New York.
Now the Centers for Disease Control is worrying about what's lingering in all the standing water along the Gulf after Isaac.
The CDC is offering help to states hit the hardest by flooding.
Nearly 1,600 infections have been reported and 66 people have died.
"It's a late summer disease, so the fact that we've got so many cases this early and it's so widespread really does not bode well," says Joe Conlon of the American Mosquito Control Association.
Experts recommend the four D's; dressing in long sleeves and pants, staying indoors at dusk and dawn, using Deet bug repellent, and draining pools or puddles of warm water.
There is no vaccine for West Nile but there are increased calls to speed up development.
