It was found in a remote, low-lying area of the county which is known for having standing water.

There’s good news on the mosquito front.

Delaware has not seen any sign of Eastern Equine Encephalitis so far this year.

And evidence of West Nile Virus has been light in the First State.

Meanwhile, on the Maryland Eastern Shore and Virginia there has been no sign of Eastern Equine Encephalitis while all the cases of West Nile Virus have been on the Western Shore.

State officials say the drier-than-normal conditions have been the key reason but they note that the mosquito season begins in earnest starting mid-August and ending in early October.
