The West Nile Virus has returned to Delaware.
Tests this week confirmed its presence when four birds turned up positive for the virus in July.
Three tested positive in New Castle County and one in Kent County according to the US Interior Department.
US officials also found that in Maryland the virus was confirmed in mosquitos last month in Montgomery County.
The Interior Department said that no mosquitos turned up positive in either Virginia or Delaware for the West Nile virus.
The Salisbury Daily Times reports that this season there haven’t been any birds to test positive in Virginia and Maryland.
